我在此处Chat server example设置并启动了聊天服务器示例。 我可以使用broswer和java socket.io客户端输入登录名并连接并发送消息。
但我无法使用python socketio-client登录聊天服务器。 下面是python客户端代码： $ cat client.py，端口更改为3001，原始为3000
#!/usr/bin/env python
from socketIO_client import SocketIO, BaseNamespace
class MyNamespace(BaseNamespace):
def connect(self, *args):
print('on_connect', args)
def on_connect(self, *args):
print('on_connect', args)
def user(self, *args):
print('on_aaa_response', args)
def on_aaa_response(self, *args):
print('on_aaa_response', args)
socketIO = SocketIO('localhost', 3001)
namespace = "chat"
event_name = "connect"
my_namespace = socketIO.define(MyNamespace, "/")
#my_namespace = socketIO.define(MyNamespace, "/my_namespace")
my_namespace.emit(event_name, {"message": "from python socketio-client"})
socketIO.wait(seconds=1)
以下是运行时的日志：
$ python3 client.py
Traceback (most recent call last):

在节点聊天服务器上，我添加了DEBUG = *来查看日志，当python客户端测试程序运行时，服务器输出如下：

问题： 有没有任何示例使用python socket.io客户端与聊天示例服务器？ 或者我的测试代码有什么问题？或者有人可以提示调试吗？
