Raisable HTTP Exceptions

## Install

Simply install the package from [PyPI](https://pypi.org/project/http-exceptions/).

```sh
$ pip install -U http-exceptions
```

And that is it, you are ready to raise HTTP Exceptions.

## What is it good for?

1. Saves writing boilerplate code:

   Converts this:

   ```py
   # e.g. app/internal.py
   def some_function() -> None:
       raise SomeError()

   # e.g. app/api.py
   def api(request: Request) -> Response:
       try:
           response = some_function()
       except SomeError:
           response = Response(status_code=403)
       return response
   ```

   into this:

   ```py
   # e.g. app/internal.py
   from http_exceptions import ForbiddenException

   def some_function() -> None:
       raise ForbiddenException()

   # e.g. app/api.py
   def api(request: Request) -> None:
       return some_function()
   ```

2. Dynamic exception raising:

   ```py
   from http_exceptions import HTTPException

   def raise_from_status(response: Response) -> None:
       if 400 <= response.status < 600:
           raise HTTPException.from_status_code(status_code=response.status_code)(message=response.text)
   ```

   ```py
   >>> response = Response(status_code=403)
   >>> raise_from_status(response=response)  # ForbiddenException raised
   ```

## What else?

### `HTTPException`

Base class that provides all the exceptions to be raised.

### `HTTPExceptions.from_status_code(status_code=status_code)`

Returns the relevant Exception corresponding to `status_code`

e.g. `HTTPExceptions.from_status_code(status_code=431)` -> `RequestHeaderFieldsTooLargeException`

### `ClientException`

Subclass of `HTTPException` serving as a base class for exceptions with statuses in the [400, 499] range.

```py
from http_exceptions import ClientException, RequestHeaderFieldsTooLargeException

try:
    raise RequestHeaderFieldsTooLargeException  # 431 - Client exception
except ClientException:
    # exception is caught here
    pass
```

### `ServerException`

Subclass of `HTTPException` serving as a base class for exceptions with statuses in the [500, 599] range.

```py
from http_exceptions import HTTPVersionNotSupportedException, ServerException

try:
    raise HTTPVersionNotSupportedException  # 505 - Server exception
except ServerException:
    # exception is caught here
    pass
```
