Question

我想用python编写一个简单的socket.io客户端，以连接到通常通过浏览器+ javascript访问的外部socket.io服务器的特定名称空间。

在浏览器中，连接的工作方式如下：首先，页面https://url:port/socket.io/1/?t=1562423475873被加载，返回类似于ACKHJADICSBVFUIASBFAKJSDN:60:60:websocket,xhr-polling,jsonp-polling

的行

然后，建立了与wss://url:port/socket.io/1/websocket/ACKHJADICSBVFUIASBFAKJSDN的连接

对于python，我编写了以下代码。

import socketio

sio = socketio.Client(logger=True, engineio_logger=True)

class MyCustomNamespace(socketio.ClientNamespace):
    def on_connect(self):
        print("I'm connected!")

    def on_disconnect(self):
        print("I'm disconnected!")

sio.register_namespace(MyCustomNamespace('/ns'))

socketiopath = "socket.io/1/"

sio.connect("https://url:port", namespaces=["/ns"],  socketio_path=socketiopath, transports=["websocket"])

while True:
    sio.wait()

此代码无效。消息“我已连接！”不打印。我得到以下记录器输出：

Attempting WebSocket connection to wss://url:port/socket.io/1/?transport=websocket&EIO=3

  File "test.py", in <module>
    sio.connect("https://url:port", namespaces=["/ns"],  socketio_path=socketiopath, transports=["websocket"])

    websock.connect(url, **options)
  File "/home/user/.local/lib/python3.6/site-packages/websocket/_core.py", line 226, in connect
    self.handshake_response = handshake(self.sock, *addrs, **options)
  File "/home/user/.local/lib/python3.6/site-packages/websocket/_handshake.py", line 79, in handshake
    status, resp = _get_resp_headers(sock)
  File "/home/user/.local/lib/python3.6/site-packages/websocket/_handshake.py", line 158, in _get_resp_headers
    status, resp_headers, status_message = read_headers(sock)
  File "/home/user/.local/lib/python3.6/site-packages/websocket/_http.py", line 305, in read_headers
    line = recv_line(sock)
  File "/home/user/.local/lib/python3.6/site-packages/websocket/_socket.py", line 123, in recv_line
    c = recv(sock, 1)
  File "/home/user/.local/lib/python3.6/site-packages/websocket/_socket.py", line 115, in recv
    "Connection is already closed.")
websocket._exceptions.WebSocketConnectionClosedException: Connection is already closed.

你能告诉我，我想念什么吗？

socket.io客户端无法连接到服务器。 “连接已关闭”
