尝试连接时发生python信号器500服务器错误

Question

我试图用这个库连接到信号器api

https://pypi.org/project/signalr-client/

这是我的密码

from requests import Session
from signalr import Connection

with Session() as session:
    #create a connection
    connection = Connection("https://firouzex.exphoenixtrade.com/realtime", session)

    #get chat hub
    chat = connection.register_hub('GetNewAPIToken')

    #start a connection
    connection.start()

但我得到了这个错误

Answer 1

我无法重现你的错误。这个问题可能是由于损坏或过时的软件包造成的，也许重新安装可以解决您的问题。SignalR库依赖于这些包

certifi, idna, chardet, urllib3, requests, websocket-client, greenlet, pycparser, cffi, gevent, sseclient, signalr-client

要重新安装，请先卸载这些软件包

然后重新安装

python -m pip install certifi, idna, chardet, urllib3, requests, websocket-client, greenlet, pycparser, cffi, gevent, sseclient, signalr-client  upgrade
