socket.io的Python客户端中文encode问题

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&＃xff0c;简单说就是编码问题。

Traceback (most recent call last):File "sub.py", line 24, in socketIO.wait()File "/usr/local/lib/python3.5/site-packages/socketIO_client/__init__.py", line 232, in waitself._process_packets()File "/usr/local/lib/python3.5/site-packages/socketIO_client/__init__.py", line 254, in _process_packetsfor engineIO_packet in self._transport.recv_packet():File "/usr/local/lib/python3.5/site-packages/socketIO_client/transports.py", line 155, in recv_packetsix.b(packet_text))File "/usr/local/lib/python3.5/site-packages/six.py", line 620, in breturn s.encode("latin-1")
UnicodeEncodeError: &＃39;latin-1&＃39; codec can&＃39;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&＃xff0c;例中跟six.py在同一目录下&＃xff0c;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&＃xff0c;在144行左右的位置找到recv_packet函数

   def recv_packet(self):try:packet_text &＃61; self._connection.recv()except websocket.WebSocketTimeoutException as e:raise TimeoutError(&＃39;recv timed out (%s)&＃39; % e)except websocket.SSLError as e:raise ConnectionError(&＃39;recv disconnected by SSL (%s)&＃39; % e)except websocket.WebSocketConnectionClosedException as e:raise ConnectionError(&＃39;recv disconnected (%s)&＃39; % e)except socket.error as e:raise ConnectionError(&＃39;recv disconnected (%s)&＃39; % e)engineIO_packet_type, engineIO_packet_data &＃61; 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))为six.u(packet_text))&＃xff0c;修改后保存.

5. 再次运行代码接收中文消息&＃xff0c;代码正常运行.
