HTTP/2 stream not closed cleanly

[mavic111]

To reproduce error:

from curl_cffi import requests

client = requests.Session(impersonate="chrome110")

res = client.get('https://google.com')
print("Google", res.status_code)
res = client.get('https://shopee.co.id')
print("Shopee", res.status_code)

Sorry, I can not reproduce this. Network problems are not always reproducible, especially http2 related ones.

This should be resolved if you force libcurl to use http1.1 only. Unfortunately, I did not expose the interface for setting this option easily, which should be fixed in the next minor version. For now, you can add one line here to use http1.1 explicitly.

CURL_HTTP_VERSION_1_1 = 2
c.setopt(CurlOpt.HTTP_VERSION, CURL_HTTP_VERSION_1_1)

it works, thanks.

For v0.5.8 above, use this:

from curl_cffi import requests, CurlHttpVersion

requests.get("https://example.com", http_version=CurlHttpVersion.V1_1)
