What does 'RemoteProtocolError: illegal request line' mean?
What does 'RemoteProtocolError: illegal request line' mean?
我正在 Apple Push Notifications 上处理推送通知，它仅使用 HTTP/2（因此无法使用 requests）并保留得到 httpx.RemoteProtocolError: illegal request line。我不知道这是什么意思：
>>> import httpx
>>> httpx.__version__
'0.18.2'

问题是您需要安装额外的依赖项并显式启用 http2：
$ pip install httpx[http2]
和
import httpx
client = httpx.Client(http2=True)
client.post('https://api.development.push.apple.com:443/3/device/<device-token>')
我正在 Apple Push Notifications 上处理推送通知，它仅使用 HTTP/2（因此无法使用 requests）并保留得到 httpx.RemoteProtocolError: illegal request line。我不知道这是什么意思：
