How do I manage a proxy server from within another Python app?

[JJTech0130]

I would really like to be able to start, configure, and manage an HTTP proxy from within my Python application (built with Quart).

I don't think I can get what I want done with the DumpManager API, as it was giving me trouble and not giving me control over its execution (for example, it had trouble when the event loop changed out from under it due to Quart hot-reloading).

Instead, I'm trying to directly use the mitmproxy.proxy API, as exemplified by the test in mitmproxy.proxy.server. However, that only shows a "reverse" proxy, and I'm looking for a "normal" HTTP proxy and can't find any documentation on that.

Are there any existing projects that implement this, or other places I could look for help? If not, what exactly do I need to setup to make this work: I assume I need to change the layers in layer_stack, but I'm not sure what layers I would need.

I thing Addons are the solution, with addons you can include mitmproxy as a normal python library

The problem with Addons is that means that my app is driven by mitmproxy, right? As in, I would have to start mitmdump or another tool and it would happen to load my app.
Instead, I want my app to be the primary thing (it can do a lot of its function w/o mitmproxy and be able to start mitmproxy inside it when it wants to.

You can spawn a mitmdump process from your app and use some form of IPC to communicate with an addon.

[JJTech0130]

Sure, but it would be a lot easier if I could just call whatever underlying API directly, considering my app is already in Python

[Prinzhorn]

Sure, but that's not a use-case we currently support.
