Description: Selenium Wire
        =============
        
        Selenium Wire extends Selenium's Python bindings to give you access to the underlying requests made by the browser. You author your code in the same way as you do with Selenium, but you get extra APIs for inspecting requests and responses and making changes to them on the fly.

        Installation
        ~~~~~~~~~~~~
        
        Install using pip:
        
        .. code:: bash
        
            pip install selenium-wire
        
        If you get an error about not being able to build cryptography, you may be running an old version of pip. Try upgrading pip with ``python -m pip install --upgrade pip``, and then re-run the above command.
        
        Browser Setup
        -------------
        
        No specific configuration should be necessary except to ensure that you have downloaded the `ChromeDriver`_ and `GeckoDriver`_ for Chrome and Firefox to be remotely controlled - the same as if you were using Selenium directly. Once downloaded, these executables should be placed somewhere on your PATH.
        
        .. _`ChromeDriver`: https://sites.google.com/a/chromium.org/chromedriver/
        
        .. _`GeckoDriver`: https://github.com/mozilla/geckodriver/
        
        OpenSSL
        -------
        
        Selenium Wire requires OpenSSL for decrypting HTTPS requests. This is normally already installed on most systems, but if it's not you can install it with:
        
        **Linux**
        
        .. code:: bash
        
            # For apt based Linux systems
            sudo apt install openssl
        
            # For RPM based Linux systems
            sudo yum install openssl
        
            # For Linux alpine
            sudo apk add openssl
        
        **MacOS**
        
        .. code:: bash
        
            brew install openssl
        
        **Windows**
        
        No installation is required.
        
        Creating the Webdriver
        ~~~~~~~~~~~~~~~~~~~~~~
        
        Ensure that you import ``webdriver`` from the ``seleniumwire`` package:
        
        .. code:: python
        
            from seleniumwire import webdriver
        
        For sub-packages of ``webdriver``, you should continue to import these directly from ``selenium``. For example, to import ``WebDriverWait``:
        
        .. code:: python
        
            # Sub-packages of webdriver must still be imported from `selenium` itself
            from selenium.webdriver.support.ui import WebDriverWait
        
        **Chrome and Firefox**
        
        For Chrome and Firefox, you don't need to do anything special. Just instantiate the webdriver as you would normally with ``webdriver.Chrome()`` or ``webdriver.Firefox()`` passing in any `desired capabilities`_ and browser specific options for `Chrome`_ or `Firefox`_ , such as the executable path, headless mode etc. Selenium Wire also has it's `own options`_ that can be passed in the ``seleniumwire_options`` attribute.
        
        .. _`own options`: #all-options
        .. _`desired capabilities`: https://selenium-python.readthedocs.io/api.html#desired-capabilities
        .. _`Chrome`: https://selenium-python.readthedocs.io/api.html#module-selenium.webdriver.chrome.options
        .. _`Firefox`: https://selenium-python.readthedocs.io/api.html#module-selenium.webdriver.firefox.options
        
        **Remote**
        
        Selenium Wire has limited support for using the remote webdriver client. When you create an instance of the remote webdriver, you need to specify the hostname or IP address of the machine (or container) running Selenium Wire. This allows the remote instance to communicate back to Selenium Wire with its requests and responses.
        
        .. code:: python
        
            options = {
                'addr': 'hostname_or_ip'  # Address of the machine running Selenium Wire
            }
            driver = webdriver.Remote(
                command_executor='http://www.example.com',
                seleniumwire_options=options
            )
        
        If the machine running the browser needs to use a different address to talk to the machine running Selenium Wire, you need to configure the browser manually. `This issue <https://github.com/wkeeling/selenium-wire/issues/220>`_ goes into more detail.
        
        Accessing Requests
        ~~~~~~~~~~~~~~~~~~
        
        Selenium Wire captures all HTTP/HTTPS traffic made by the browser [1]_.
        
        ``driver.requests``
            The list of captured requests in chronological order.
        
        ``driver.last_request``
            Convenience attribute for retrieving the most recently captured request. This is more efficient than using ``driver.requests[-1]``.
        
        ``driver.wait_for_request(pat, timeout=10)``
            This method will wait until it sees a request matching a pattern. The ``pat`` attribute will be matched within the request URL. ``pat`` can be a simple sub-string or a regex. Note that ``driver.wait_for_request()`` doesn't *make* a request, it just *waits* for a previous request made by some other action - and it will return the first request it finds. Also note that since ``pat`` can be a regex, you must escape special characters such as question marks with a slash. A ``TimeoutException`` is raised if no match is found within the timeout period.
        
            For example, to wait for an AJAX request to return after a button is clicked:
        
            .. code:: python
        
                # Click a button that triggers a background request to https://server/api/products/12345/
                button_element.click()
        
                # Wait for the request/response to complete
                request = driver.wait_for_request('/api/products/12345/')
        
        ``driver.har``
            A JSON formatted HAR archive of HTTP transactions that have taken place. HAR capture is turned off by default, and you must set the ``enable_har`` `option`_ to ``True`` before using ``driver.har``.
        
        ``driver.iter_requests()``
            Returns an iterator over captured requests. Useful when dealing with a large number of requests.
        
        ``driver.request_interceptor``
            Used to set a request interceptor.
        
        ``driver.response_interceptor``
            Used to set a response interceptor. See `Intercepting Requests and Responses`_.
        
        **Clearing Requests**
        
        To clear previously captured requests and HAR entries, use ``del``:
        
        .. code:: python
        
            del driver.requests
        
        .. [1] Selenium Wire ignores OPTIONS requests by default, as these are typically uninteresting and just add overhead. If you want to capture OPTIONS requests, you need to set the ``ignore_http_methods`` `option`_ to ``[]``.
        
        .. _`option`: #all-options
        
        Request Objects
        ~~~~~~~~~~~~~~~
        
        Request objects have the following attributes.
        
        ``body``
            The request body as ``bytes``. If the request has no body the value of ``body`` will be empty, i.e. ``b''``.
        
        ``cert``
            Information about the server SSL certificate in dictionary format. Empty for non-HTTPS requests.
        
        ``date``
            The datetime the request was made.
        
        ``headers``
            A dictionary-like object of request headers. Headers are case-insensitive and duplicates are permitted. Asking for ``request.headers['user-agent']`` will return the value of the ``User-Agent`` header. If you wish to replace a header, make sure you delete the existing header first with ``del request.headers['header-name']``, otherwise you'll create a duplicate.
        
        ``method``
            The HTTP method, e.g. ``GET`` or ``POST`` etc.
        
        ``params``
            A dictionary of request parameters. If a parameter with the same name appears more than once in the request, it's value in the dictionary will be a list.
        
        ``path``
            The request path, e.g. ``/some/path/index.html``
        
        ``querystring``
            The query string, e.g. ``foo=bar&spam=eggs``
        
        ``response``
           The response associated with the request. This will be ``None`` if the request has no response.
        
        ``url``
            The request URL, e.g. ``https://server/some/path/index.html?foo=bar&spam=eggs``
        
        ``ws_messages``
            Where the request is a websocket handshake request (normally with a URL starting ``wss://``), then ``ws_messages`` will contain a list of any websocket messages sent and received. See `WebSocketMessage Objects`_.
        
        Request objects have the following methods.
        
        ``abort(error_code=403)``
            Trigger immediate termination of the request with the supplied error code. For use within request interceptors. See `Example: Block a request`_.
        
        ``create_response(status_code, headers=(), body=b'')``
            Create a response and return it without sending any data to the remote server. For use within request interceptors. See `Example: Mock a response`_.
        
        WebSocketMessage Objects
        ------------------------
        
        These objects represent websocket messages sent between the browser and server and vice versa. They are held in a list by ``request.ws_messages`` on websocket handshake requests. They have the following attributes.
        
        ``content``
            The message content which may be either ``str`` or ``bytes``.
        
        ``date``
            The datetime of the message.
        
        ``from_client``
            ``True`` when the message was sent by the client and ``False`` when sent by the server.
        
        Response Objects
        ~~~~~~~~~~~~~~~~
        
        Response objects have the following attributes.
        
        ``body``
            The response body as ``bytes``. If the response has no body the value of ``body`` will be empty, i.e. ``b''``.
        
        ``date``
            The datetime the response was received.
        
        ``headers``
             A dictionary-like object of response headers. Headers are case-insensitive and duplicates are permitted. Asking for ``response.headers['content-length']`` will return the value of the ``Content-Length`` header. If you wish to replace a header, make sure you delete the existing header first with ``del response.headers['header-name']``, otherwise you'll create a duplicate.
        
        ``reason``
            The reason phrase, e.g. ``OK`` or ``Not Found`` etc.
        
        ``status_code``
            The status code of the response, e.g. ``200`` or ``404`` etc.
        
        
        Intercepting Requests and Responses
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
        
        Selenium Wire allows you to modify requests and responses on the fly using interceptors. An interceptor is a function that gets invoked with requests and responses as they pass through Selenium Wire. Within an interceptor you can modify the request and response as you see fit.
        
        You set your interceptor functions using the ``driver.request_interceptor`` and ``driver.response_interceptor`` attributes before you start using the driver. A request interceptor should accept a single argument for the request. A response interceptor should accept two arguments, one for the originating request and one for the response.
        
        Example: Add a request header
        -----------------------------
        
        .. code:: python
        
            def interceptor(request):
                request.headers['New-Header'] = 'Some Value'
        
            driver.request_interceptor = interceptor
            driver.get(...)
        
            # All requests will now contain New-Header
        
        How can I check that a header has been set correctly? You can print the headers from captured requests after the page has loaded (using ``driver.requests``), or alternatively point the webdriver at https://httpbin.org/headers which will echo the request headers back to the browser so you can view them.
        
        Example: Replace an existing request header
        -------------------------------------------
        
        Duplicate header names are permitted in an HTTP request, so before setting the replacement header you must first delete the existing header using ``del`` like in the following example, otherwise two headers with the same name will exist (``request.headers`` is a special dictionary-like object that allows duplicates).
        
        .. code:: python
        
            def interceptor(request):
                del request.headers['Referer']  # Remember to delete the header first
                request.headers['Referer'] = 'some_referer'  # Spoof the referer
        
            driver.request_interceptor = interceptor
            driver.get(...)
        
            # All requests will now use 'some_referer' for the referer
        
        Example: Add a response header
        ------------------------------
        
        .. code:: python
        
            def interceptor(request, response):  # A response interceptor takes two args
                if request.url == 'https://server.com/some/path':
                    response.headers['New-Header'] = 'Some Value'
        
            driver.response_interceptor = interceptor
            driver.get(...)
        
            # Responses from https://server.com/some/path will now contain New-Header
        
        Example: Add a request parameter
        --------------------------------
        
        Request parameters work differently to headers in that they are calculated when they are set on the request. That means that you first have to read them, then update them, and then write them back - like in the following example. Parameters are held in a regular dictionary, so parameters with the same name will be overwritten.
        
        .. code:: python
        
            def interceptor(request):
                params = request.params
                params['foo'] = 'bar'
                request.params = params
        
            driver.request_interceptor = interceptor
            driver.get(...)
        
            # foo=bar will be added to all requests
        
        Example: Update JSON in a POST request body
        -----------------------------------------------
        
        .. code:: python
        
            import json
        
            def interceptor(request):
                if request.method == 'POST' and request.headers['Content-Type'] == 'application/json':
                    # The body is in bytes so convert to a string
                    body = request.body.decode('utf-8')
                    # Load the JSON
                    data = json.loads(body)
                    # Add a new property
                    data['foo'] = 'bar'
                    # Set the JSON back on the request
                    request.body = json.dumps(data).encode('utf-8')
                    # Update the content length
                    del request.headers['Content-Length']
                    request.headers['Content-Length'] = str(len(request.body))
        
            driver.request_interceptor = interceptor
            driver.get(...)
        
        Example: Block a request
        ------------------------
        
        You can use ``request.abort()`` to block a request and send an immediate response back to the browser. An optional error code can be supplied. The default is 403 (forbidden).
        
        .. code:: python
        
            def interceptor(request):
                # Block PNG, JPEG and GIF images
                if request.path.endswith(('.png', '.jpg', '.gif')):
                    request.abort()
        
            driver.request_interceptor = interceptor
            driver.get(...)
        
            # Requests for PNG, JPEG and GIF images will result in a 403 Forbidden
        
        Example: Mock a response
        ------------------------
        
        You can use ``request.create_response()`` to send a custom reply back to the browser. No data will be sent to the remote server.
        
        .. code:: python
        
            def interceptor(request):
                if request.url == 'https://server.com/some/path':
                    request.create_response(
                        status_code=200,
                        headers={'Content-Type': 'text/html'},  # Optional headers dictionary
                        body='<html>Hello World!</html>'  # Optional body
                    )
        
            driver.request_interceptor = interceptor
            driver.get(...)
        
            # Requests to https://server.com/some/path will have their responses mocked
        
        *Have any other examples you think could be useful? Feel free to submit a PR.*
        
        Unset an interceptor
        --------------------
        
        To unset an interceptor, use ``del``:
        
        .. code:: python
        
            del driver.request_interceptor
            del driver.response_interceptor
        
        Limiting Request Capture
        ~~~~~~~~~~~~~~~~~~~~~~~~
        
        Selenium Wire works by redirecting browser traffic through an internal proxy server it spins up in the background. As requests flow through the proxy they are intercepted and captured. Capturing requests can slow things down a little, but there are a few things you can do to restrict what gets captured.
        
        ``driver.scopes``
            This accepts a list of regular expressions that will match the URLs to be captured. It should be set on the driver before making any requests. When empty (the default) all URLs are captured.
        
            .. code:: python
        
                driver.scopes = [
                    '.*stackoverflow.*',
                    '.*github.*'
                ]
        
                driver.get(...)  # Start making requests
        
                # Only request URLs containing "stackoverflow" or "github" will now be captured
        
            Note that even if a request is out of scope and not captured, it will still travel through Selenium Wire.
        
        ``seleniumwire_options.disable_capture``
            Use this option to switch off request capture. Requests will still pass through Selenium Wire and through any upstream proxy you have configured, but they won't be stored.
        
            .. code:: python
        
                options = {
                    'disable_capture': True  # Don't store any requests
                }
                driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``seleniumwire_options.exclude_hosts``
            Use this option to bypass Selenium Wire entirely. Any requests made to addresses listed here will go direct from the browser to the server without involving Selenium Wire. Note that if you've configured an upstream proxy then these requests will also bypass that proxy.
        
            .. code:: python
        
                options = {
                    'exclude_hosts': ['host1.com', 'host2.com']  # Bypass Selenium Wire for these hosts
                }
                driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``request.abort()``
            You can abort a request early by using ``request.abort()`` from within a `request interceptor`_. This will send an immediate response back to the client without the request travelling any further. You can use this mechanism to block certain types of requests (e.g. images) to improve page load performance.
        
            .. code:: python
        
                def interceptor(request):
                    # Block PNG, JPEG and GIF images
                    if request.path.endswith(('.png', '.jpg', '.gif')):
                        request.abort()
        
                driver.request_interceptor = interceptor
        
                driver.get(...)  # Start making requests
        
        .. _`request interceptor`: #intercepting-requests-and-responses
        
        Proxies
        ~~~~~~~
        
        If the site you are accessing sits behind a proxy server you can tell Selenium Wire about that proxy server in the options you pass to the webdriver.
        
        The configuration takes the following format:
        
        .. code:: python
        
            options = {
                'proxy': {
                    'http': 'http://192.168.10.100:8888',
                    'https': 'https://192.168.10.100:8888',
                    'no_proxy': 'localhost,127.0.0.1'
                }
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        To use HTTP Basic Auth with your proxy, specify the username and password in the URL:
        
        .. code:: python
        
            options = {
                'proxy': {
                    'https': 'https://user:pass@192.168.10.100:8888',
                }
            }
        
        For authentication other than Basic, you can supply the full value for the ``Proxy-Authorization`` header using the ``custom_authorization`` option. For example, if your proxy used the Bearer scheme:
        
        .. code:: python
        
            options = {
                'proxy': {
                    'https': 'https://192.168.10.100:8888',  # No username or password used
                    'custom_authorization': 'Bearer mytoken123'  # Custom Proxy-Authorization header value
                }
            }
        
        Note that the ``custom_authorization`` option is only supported by the `default backend`_. More info on the ``Proxy-Authorization`` header can be found `here <https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Proxy-Authorization>`__.
        
        .. _`default backend`: #backends
        
        The proxy configuration can also be loaded through environment variables called ``HTTP_PROXY``, ``HTTPS_PROXY`` and ``NO_PROXY``:
        
        .. code:: bash
        
            $ export HTTP_PROXY="http://192.168.10.100:8888"
            $ export HTTPS_PROXY="https://192.168.10.100:8888"
            $ export NO_PROXY="localhost,127.0.0.1"
        
        SOCKS
        -----
        
        Using a SOCKS proxy is the same as using an HTTP based one, but with the scheme set to ``socks5``:
        
        .. code:: python
        
            options = {
                'proxy': {
                    'http': 'socks5://user:pass@192.168.10.100:8888',
                    'https': 'socks5://user:pass@192.168.10.100:8888',
                    'no_proxy': 'localhost,127.0.0.1'
                }
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        You can leave out the ``user`` and ``pass`` if your proxy doesn't require authentication.
        
        As well as ``socks5``, the schemes ``socks4`` and ``socks5h`` are supported. Use ``socks5h`` when you want DNS resolution to happen on the proxy server rather than on the client.
        
        **Using Selenium Wire with Tor**
        
        See `this example <https://gist.github.com/woswos/38b921f0b82de009c12c6494db3f50c5>`_ if you want to run Selenium Wire with Tor.
        
        Bot Detection
        ~~~~~~~~~~~~~
        
        Selenium Wire will automatically integrate itself with `undetected-chromedriver`_ if it finds it in your environment. This library will transparently modify ChromeDriver to prevent it from triggering anti-bot measures on websites.
        
        .. _`undetected-chromedriver`: https://github.com/ultrafunkamsterdam/undetected-chromedriver
        
        If you wish to take advantage of this, make sure you have undetected-chromedriver installed:
        
        .. code:: bash
        
            pip install undetected-chromedriver
        
        Then just use ``webdriver.Chrome()`` as you would normally, making sure that you import it from the ``seleniumwire`` package. If you use ``ChromeOptions`` this should also be imported from the ``seleniumwire`` package:
        
        .. code:: python
        
            from seleniumwire import webdriver
        
            chrome_options = webdriver.ChromeOptions()
            sw_options = {...}
        
            driver = webdriver.Chrome(  # Optimized for bot detection
                options=chrome_options,
                seleniumwire_options=sw_options
            )
        
        The first time you run the webdriver it will download and patch the ChromeDriver binary in the background.
        
        You can check that undetected_chromedriver is being used by looking for the log messages it generates. You just need to ensure that you've activated logging at the top of your script or program first - for example:
        
        .. code:: python
        
            import logging
            logging.basicConfig(level=logging.INFO)
            logging.getLogger('undetected_chromedriver').level = logging.INFO
        
            from seleniumwire import webdriver
        
            ... code ...
        
        You should see messages similar to:
        
        .. code:: bash
        
            INFO:undetected_chromedriver:Selenium patched. Safe to import Chrome / ChromeOptions
            INFO:undetected_chromedriver:starting undetected_chromedriver.Chrome((), ...
        
        Note that this functionality is currently experimental.
        
        Backends
        ~~~~~~~~
        
        Selenium Wire allows you to change the backend component that performs request capture. Currently two backends are supported: the backend that ships with Selenium Wire (the default) and the mitmproxy backend.
        
        The default backend is adequate for most purposes. However, in certain cases you may find you get better performance with the mitmproxy backend.
        
        The mitmproxy backend relies upon the powerful open source `mitmproxy proxy server`_ being installed in your environment.
        
        .. _`mitmproxy proxy server`: https://mitmproxy.org/
        
        To switch to the mitmproxy backend, first install the mitmproxy package:
        
        .. code:: bash
        
            pip install mitmproxy
        
        Once installed, set the ``backend`` option in Selenium Wire's options to ``mitmproxy``:
        
        .. code:: python
        
            options = {
                'backend': 'mitmproxy'
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        You can pass `mitmproxy specific options`_ to the mitmproxy backend by prefixing them with **mitm_**. For example, to change the location of the mitmproxy configuration directory which lives in your home folder by default:
        
        .. _`mitmproxy specific options`: https://docs.mitmproxy.org/stable/concepts-options/#available-options
        
        .. code:: python
        
            options = {
                'backend': 'mitmproxy',
                'mitm_confdir': '/tmp/.mitmproxy'  # Switch the location to /tmp
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        Mitmproxy includes options that can help with performance such as ``mitm_stream_large_bodies``. Setting this to a low value (e.g. '1k') has been shown to improve performance, in conjunction with the use of ``driver.scopes``.
        
        *Note that the mitmproxy backend won't work with upstream SOCKS proxies.*
        
        Certificates
        ~~~~~~~~~~~~
        
        Selenium Wire uses it's own CA certificate to decrypt HTTPS traffic. It is not normally necessary for the browser to trust this certificate because Selenium Wire tells the browser to add it as an exception. This will allow the browser to function normally, but it will display a "Not Secure" message in the address bar. If you wish to get rid of this message you can install the CA certificate manually.
        
        For the default backend, you can download the CA certificate `here <https://github.com/wkeeling/selenium-wire/raw/master/seleniumwire/ca.crt>`__. Once downloaded, navigate to "Certificates" in your browser settings and import the certificate in the "Authorities" section.
        
        If you are using the mitmproxy backend, you can follow `these instructions <https://docs.mitmproxy.org/stable/concepts-certificates/#installing-the-mitmproxy-ca-certificate-manually>`_ to install the CA certificate.
        
        All Options
        ~~~~~~~~~~~
        
        A summary of all options that can be passed to Selenium Wire via the ``seleniumwire_options`` webdriver attribute.
        
        ``addr``
            The IP address or hostname of the machine running Selenium Wire. This defaults to 127.0.0.1. You may want to change this to the public IP of the machine (or container) if you're using the `remote webdriver`_.
        
        .. code:: python
        
            options = {
                'addr': '192.168.0.10'  # Use the public IP of the machine
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        .. _`remote webdriver`: #creating-the-webdriver
        
        ``auto_config``
            Whether Selenium Wire should auto-configure the browser for request capture. ``True`` by default.
        
        ``backend``
            The backend component that Selenium Wire will use to capture requests. The currently supported values are ``default`` (same as not specifying) or ``mitmproxy``.
        
        .. code:: python
        
            options = {
                'backend': 'mitmproxy'  # Use the mitmproxy backend (see limitations above)
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``disable_capture``
            Disable request capture. When ``True`` nothing gets stored.
        
        .. code:: python
        
            options = {
                'disable_capture': True  # Don't store any requests.
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``disable_encoding``
            Ask the server to send back un-compressed data. When ``True`` this sets the ``Accept-Encoding`` header to ``identity`` for all outbound requests. Note that it won't always work - sometimes the server may ignore it. The default is ``False``.
        
        .. code:: python
        
            options = {
                'disable_encoding': True  # Ask the server not to compress the response
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``enable_har``
            When ``True`` a HAR archive of HTTP transactions will be kept which can be retrieved with ``driver.har``. ``False`` by default.
        
        .. code:: python
        
            options = {
                'enable_har': True  # Capture HAR data, retrieve with driver.har
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``exclude_hosts``
            A list of addresses for which Selenium Wire should be bypassed entirely. Note that if you have configured an upstream proxy then requests to excluded hosts will also bypass that proxy.
        
        .. code:: python
        
            options = {
                'exclude_hosts': ['google-analytics.com']  # Bypass these hosts
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``ignore_http_methods``
            A list of HTTP methods (specified as uppercase strings) that should be ignored by Selenium Wire and not captured. The default is ``['OPTIONS']`` which ignores all OPTIONS requests. To capture all request methods, set ``ignore_http_methods`` to an empty list:
        
        .. code:: python
        
            options = {
                'ignore_http_methods': []  # Capture all requests, including OPTIONS requests
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``port``
            The port number that Selenium Wire's backend listens on. You don't normally need to specify a port as a random port number is chosen automatically.
        
        .. code:: python
        
            options = {
                'port': 9999  # Tell the backend to listen on port 9999 (not normally necessary to set this)
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``proxy``
            The upstream proxy server configuration (if you're using a proxy).
        
        .. code:: python
        
            options = {
                'proxy': {
                    'http': 'http://user:pass@192.168.10.100:8888',
                    'https': 'https://user:pass@192.168.10.100:8889',
                    'no_proxy': 'localhost,127.0.0.1'
                }
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``request_storage_base_dir``
            Captured requests and responses are stored in the current user's home folder by default. You might want to change this if you're running in an environment where you don't have access to the user's home folder.

            options = {

            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``suppress_connection_errors``
            Whether to suppress connection related tracebacks. The default is ``True`` so that harmless errors that commonly occur at browser shutdown do not alarm users. When suppressed, the connection error message is logged at DEBUG level without a traceback. Set to ``False`` to allow exception propagation and see full tracebacks.
            *Applies to the default backend only.*
        
        .. code:: python
        
            options = {
                'suppress_connection_errors': False  # Show full tracebacks for any connection errors
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
        
        ``verify_ssl``
            Whether SSL certificates should be verified. The default is ``False`` which prevents errors with self-signed certificates.
        
        .. code:: python
        
            options = {
                'verify_ssl': True  # Verify SSL certificates but beware of errors with self-signed certificates
            }
            driver = webdriver.Chrome(seleniumwire_options=options)
