Messenger 机器人的 ConnectionError

Question

我正在使用带有 pymessenger 的 messenger 机器人（此处为链接 https://github.com/davidchua/pymessenger）。 有时，当我尝试使用 bot.send_text_message() 或其他函数之一向用户发送消息以发送 python 包的消息时，我收到以下错误：

  File "C:\Python27\lib\site-packages\pymessenger\bot.py", line 29, in send_text_message
    return self._send_payload(payload)
  File "C:\Python27\lib\site-packages\pymessenger\bot.py", line 76, in _send_payload
    result = requests.post(self.base_url, json=payload).json()
  File "C:\Python27\lib\site-packages\requests\api.py", line 111, in post
    return request('post', url, data=data, json=json, **kwargs)
  File "C:\Python27\lib\site-packages\requests\api.py", line 57, in request
    return session.request(method=method, url=url, **kwargs)
  File "C:\Python27\lib\site-packages\requests\sessions.py", line 475, in request
    resp = self.send(prep, **send_kwargs)
  File "C:\Python27\lib\site-packages\requests\sessions.py", line 585, in send
    r = adapter.send(request, **kwargs)
  File "C:\Python27\lib\site-packages\requests\adapters.py", line 467, in send
    raise ConnectionError(e, request=request)
ConnectionError: HTTPSConnectionPool(host='graph.facebook.com', port=443): Max retries exceeded with url: /v2.6/me/messages?access_token=<my_token> (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x00000000422A40B8>: Failed to establish a new connection: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond',))

我想也许我向 Facebook 发出了太多请求，但只有我一个人在使用机器人，而且我正在做的请求数量是正常聊天中的一个，所以我想应该是其他的，但我不明白什么。 我正在使用 ngrok 进行回调。

尝试捕获 HTTPSConnectionPool 异常并查看其参数以查看我的意思的详细信息

except HTTPSConnectionPool as e:
    e.args
