【问题描述】：

当我尝试使用websocket.create_connection 创建连接时，我遇到了TypeError: a float is required

full_url = "wss://myurl:443/abc/def/ghi?id=asdf3nnasdfj34nasdf23"
header_conn = dict()
header_conn['Authorization'] = "Auth service=<my authorization token goes here>"  

ws = websocket.create_connection(full_url, header_conn)

显示给我的例外是：

  File "try.py", line 268, in <module>
    ws = websocket.create_connection(full_url, headers_conn1)
  File "/usr/local/lib/python2.7/dist-packages/websocket/_core.py", line 487, in create_connection
    websock.connect(url, **options)
  File "/usr/local/lib/python2.7/dist-packages/websocket/_core.py", line 211, in connect
    options.pop('socket', None))
  File "/usr/local/lib/python2.7/dist-packages/websocket/_http.py", line 71, in connect
    sock = _open_socket(addrinfo_list, options.sockopt, options.timeout)
  File "/usr/local/lib/python2.7/dist-packages/websocket/_http.py", line 106, in _open_socket
    sock.settimeout(timeout)
  File "/usr/lib/python2.7/socket.py", line 224, in meth
    return getattr(self._sock,name)(*args)
TypeError: a float is required

知道我错过了什么吗？我看到了this 链接，但我不确定如何在我的案例中应用相同的解决方案。

【参考方案1】：

websocket.create_connection 似乎将timeout 值作为第二个参数。在您的情况下，header_conn 被解释为 timeout 参数。

试试

ws = websocket.create_connection(full_url, header=header_conn)
