Retries in AsyncClient is not working for me

[mhihasan]

I am trying to access an API which alternates 200 and 500 status. That's why I need to retry once in case it returns 500 error, but for 200 response I don't need to retry.

I am trying the following way, but getting <Response [500 Server Error]> and <Response [200 Ok]> alternatively.
I need <Response [200 Ok]> always.

import asyncio

import httpx


async def get_device(device_id: str):
    transport = httpx.AsyncHTTPTransport(retries=1)
    async with httpx.AsyncClient(transport=transport) as client:
        response = await client.get(f"http://example.com/device_id/{device_id}")
    print(response) # Output: alternating `<Response [500 Server Error]>` and `<Response [200 Ok]>`


if __name__ == '__main__':
    asyncio.run(get_device("xcvbrty123"))

You'd need to describe what's not working for someone to be able to help you out with this.

Probably start by telling us exactly which kind of exception is being raised?

I have added more desccription on the problem.

Right, so retries=... [gives you connection retries])(https://www.python-httpx.org/advanced/#custom-transports). Ie, if an HTTP connection couldn't be established to the server then it'll retry that.

We don't have any support for automatically retiring requests based on 5xx status codes. There's a similar discussion here... #1755
