HTTP requests2: how to deal with server that keeps the connection alive?

streammyevent

I'm trying to extract current power usage information from a P1 device with an API, but the server is poorly written and doesn't respond to the "Connection: close" header, keeping the connection alive no matter what:

*   Trying 192.168.10.22:80...
* Connected to 192.168.10.22 (192.168.10.22) port 80
> GET /api/v1/data HTTP/1.1
> Host: 192.168.10.22
> User-Agent: curl/8.4.0
> Accept: */*
> Connection: close
> Content-Type: application/json
> 
< HTTP/1.1 200 OK
< Content-Type: application/json
< Content-Length: 1178
< Access-Control-Allow-Origin: *
< 
* Connection #0 to host 192.168.10.22 left intact

This causes request2 to freeze when trying to get the response contents, like when calling 'print(http_req.text)'. Performing a GET request on any other server works fine, so it's pretty clear to me that this is the issue.

If I add a timeout to the request, like so:

http_req = requests2.get('http://192.168.10.22/api/v1/data', headers={'Content-Type': 'application/json', 'Connection': "close"}, timeout=2)

Then that just triggers an error and crashes the application.

Many servers keep the connection alive by default, leading to this issue. Is there a way to work around it?
