socket.io的 Python客户

    socketIO-client是python实现的SocketIO客户端。

    问题

    当接收到中文消息时出现下方错误,简单说就是编码问题。

    Traceback (most recent call last):
      File "sub.py", line 24, in <module>
        socketIO.wait()
      File "/usr/local/lib/python3.5/site-packages/socketIO_client/__init__.py", line 232, in wait
        self._process_packets()
      File "/usr/local/lib/python3.5/site-packages/socketIO_client/__init__.py", line 254, in _process_packets
        for engineIO_packet in self._transport.recv_packet():
      File "/usr/local/lib/python3.5/site-packages/socketIO_client/transports.py", line 155, in recv_packet
        six.b(packet_text))
      File "/usr/local/lib/python3.5/site-packages/six.py", line 620, in b
        return s.encode("latin-1")
    UnicodeEncodeError: 'latin-1' codec can't encode characters in position 21-27: ordinal not in range(256)

    解决方法

    1. 找到socketIO_client的安装路径,例中跟six.py在同一目录下,路径是/usr/local/lib/python3.5/site-packages/socketIO_client/.

    2. 找到socketIO_client文件夹下的transports.py文件

    3. 用编辑器打开transports.py,在144行左右的位置找到recv_packet函数

      def recv_packet(self):
          try:
              packet_text = self._connection.recv()
          except websocket.WebSocketTimeoutException as e:
              raise TimeoutError('recv timed out (%s)' % e)
          except websocket.SSLError as e:
              raise ConnectionError('recv disconnected by SSL (%s)' % e)
          except websocket.WebSocketConnectionClosedException as e:
              raise ConnectionError('recv disconnected (%s)' % e)
          except socket.error as e:
              raise ConnectionError('recv disconnected (%s)' % e)
          engineIO_packet_type, engineIO_packet_data = parse_packet_text(
              six.b(packet_text))
          yield engineIO_packet_type, engineIO_packet_data
    4. 修改倒数第二行six.b(packet_text))six.u(packet_text)),修改后保存.

    5. 再次运行代码接收中文消息,代码正常运行.
