Initial design

[simonw]

This is a debugging tool. I want to make it easy to start iterating on things like webhooks or OAuth flows by configuring quick endpoints that return configured mock data and log the incoming request.

I got Claude 3.5 Sonnet to write most of the initial code:

I want a Django app I can use to help create HTTP debugging endpoints. It should let me configure a new path e.g. /webhooks/receive/ that the Django 404 handler then hooks into - if one is configured it can be told which HTTP status code, headers and content to return.

ALL traffic to those endpoints is logged to a Django table - full details of incoming request headers, method and body. Those can be browsed read-only in the Django admin (and deleted)

make it so I don't have to put it in the urlpatterns because it hooks ito Django's 404 handling mechanism instead

Suggestions for how this could handle request bodies that don't cleanly decode to utf-8

don't use a binary field, use a text field but still store base64 data in it if necessary and have a is_base64 boolean column that gets set to true if that happens

To get it to work correctly with DEBUG=True turned on I modified the middleware to work like this instead:

class DebugMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        response = self.get_response(request)
        if response.status_code == 404:
            path = request.path.lstrip("/")
            debug_response = debug_view(request, path)
            if debug_response:
                return debug_response
        return response
