How to dynamically update the proxy address of an object after it is created, and whether there is a similar method in HTTPX like using "session.proxies.update"?

[RavenCri]

Please tell me how to do it. Thank you very much. I need the help of the community.

import requests
session = requests.Session()
proxies = {
    "http": "http://old-proxy-ip:port",
    "https": "http://old-proxy-ip:port",
}
session.proxies.update(proxies)
new_proxies = {
    "http": "http://new-proxy-ip:port",
    "https": "http://new-proxy-ip:port",
}
session.proxies.update(new_proxies)

We don't support that usage. Proxy setup is done when you instantiate the Client.
If you need a different set of proxies, then instantiate a new Client.

I'd suggest for that use-case, a wrapper around a pool of clients.

Actually, let me revise that. A neat way to handle this would be a custom transport that rotates between different proxies. You'd then pass that transport to a single client instance.

I'd be happy to help provide guidance for someone working on this.

This would actually be a really neat project for someone to take on and share.

I guess so, but that would require me to create something that should've been implemented already. Requests does this.

If you want to understand fully why we have a different design decision here, and the implications, then you'd want to start by reviewing our Transport API vs. requests adapters, and try implementing the change to see what effect that has on lower layers of the API.

Hmm, interesting.
I'll see what magic I can do with a custom Transport.
It'd be amazing if you could pass a small example, since I'm very new to this libary lol

If I manage to write something working, I'll publish it (the project it'll be included in is open source anyways)

Hi there, have you finished yet?

No, sorry. I dropped HTTPX in favor of python3-requests as it was just easier to use,

Sorry!

Open a new client is not a good idea in some situation. Create a new client will cost about 50 ms, but in some micro-service calling requests, 50 ms is too expensive.

In HTTPX, you can't update the session's proxy dictionary dynamically like in requests. Instead, you can create a new client with the updated proxy settings.
