Question

我正在使用pysher库连接到websocket。有时，我可以看到我没有收到任何数据，并且我的journalctl中存在此错误：

Connection: Received error 4201
Exception in thread PysherEventLoop:
Traceback (most recent call last):
  File "/usr/lib/python3.6/threading.py", line 916, in _bootstrap_inner
    self.run()
  File "/usr/local/lib/python3.6/dist-packages/pysher/connection.py", line 102, in run
    self._connect()
  File "/usr/local/lib/python3.6/dist-packages/pysher/connection.py", line 126, in _connect
    self.socket.run_forever(**self.socket_kwargs)
  File "/usr/local/lib/python3.6/dist-packages/websocket/_app.py", line 207, in run_forever
    raise WebSocketException("socket is already opened")
websocket._exceptions.WebSocketException: socket is already opened
Failed send ping: socket is already closed.

我的脚本如下：

import pysher

# some code like logger, etc...

def  my_func(*args, **kwargs):
    print("processing Args:", args)
    print("processing Kwargs:", kwargs)

def connect_handler(data):
    channel = pusher.subscribe('mychannel')
    channel.bind('myevent', my_func)

try:
    pusher = pysher.Pusher(req_appkey)
    pusher.connection.bind('pusher:connection_established', connect_handler)
    pusher.connect()

    logger.info('Connection sucessfully established.')

    while not killer.kill_now:
        time.sleep(1)

except Exception as e:
    logger.info('Unexpected error occurred.')
    logger.info('Error: ', e)

我将其作为linux服务启动，当脚本未运行时它将自动启动。但是，即使在我的journalctl中发生此错误（无法被我的尝试clausula捕获），脚本循环仍在运行。

此错误是什么意思，我的websocket如何同时打开和关闭？有人可以解释一下并帮助我找到解决方案吗？

为什么pysher websocket停止工作并需要手动重启
