【问题描述】：

我正在尝试连接到 socket.io 服务器并接收消息。但是在连接时我得到 socketio.exceptions.ConnectionError: One or more namespaces failed to connect

代码：

import socketio

sio = socketio.Client()

@sio.event
def connect():
    print('connection established')
    sio.emit('login', {'token': 'token'})

@sio.event
def my_message(data):
    print('message received with ', data)

@sio.event
def disconnect():
    print('disconnected from server')

sio.connect('wss://socket.boticord.top')
sio.wait()

【问题讨论】：

您是否也拥有该服务器，还是第三方？您是否启用了 Socket.IO 日志以查看客户端和服务器之间流量交换的更多详细信息？
@Miguel 不，我无权访问服务器。问题肯定在我这边，因为一切都在 node.js 中运行。告诉我如何启用 socket.io 日志？
flask-socketio.readthedocs.io/en/latest/…
@Miguel 我启用了 socket.io 日志并得到如下输出：Attempting WebSocket upgrade to wss://socket.boticord.top/socket.io/?transport=websocket&EIO=4 WebSocket upgrade failed: connection error Sending polling GET request to https://socket.boticord.top/socket.io/?transport=polling&EIO=4&sid=WDdR53fSdPOcwGVzAAAK Unexpected status code 400 in server response, aborting 基于此，我相信 websocket 出于某种原因尝试更新，但无法更新。
在文档中还写到socket.io的服务器版本是3.0.1，客户端和服务器的版本必须相同。但是在node.js中为客户端指定了版本，我不知道如何为python安装这个版本。

【解决方案1】：

试试

sio.connect('wss://socket.boticord.top', wait_timeout = 10)

【解决方案2】：

尝试使用 python-socketio 的 4-5.x 版本或联系支持。
