Python 套接字连接无法正常工作

Question

下面是我目前使用的代码:

soc1 = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ADDR = (HOST,PORT)
soc1.connect(ADDR)
soc1.send('WILL SEND')   

运行上述代码时收到的错误消息是:

Traceback (most recent call last):
  File "C:\workspace\wx_python_test\chat_server.py", line 25, in <module>
    soc1.connect(ADDR)
  File "C:\Python27\lib\socket.py", line 224, in meth
    return getattr(self._sock,name)(*args)
socket.error: [Errno 10061] 

谁能解释一下我遇到的问题是什么以及我该如何纠正它？

Answer 1

socket.error: [Errno 10061] 表示您尝试连接的端口未打开。您需要确保端口已打开并且正在监听您要建立的连接。

看来您正在尝试测试聊天服务器。为了让聊天服务器正常工作，您需要确保它当前正在监听指定端口。

Twisted如果您之前没有检查过，它提供了一个很好的框架。
