消息传递程序中的套接字错误

Question

我目前正在尝试制作自己的私人消息程序，仅供我和我的朋友使用，并且我一直在使用＆＃34; s.listen（1）＆＃34;客户聊天程序的一部分，我不明白我遇到的原因，我尝试了很多不同的东西来弄清楚是什么问题。

错误是：

    Unhandled exception in thread started by <function GetConnected at 0x027E42F0>
    Traceback (most recent call last):
      File "client.pyw", line 84, in GetConnected
    s.listen(1)
  File "<string>", line 1, in listen
socket.error: (10022, 'Invalid argument')

Answer 1

端口号为0-65535（或者至少它们是在IPv4时代，确定v6）。

要有机会让这个工作，你应该改变：

PORT = 801111

到0-65535范围内尚未使用的东西，最好是现有的协议/应用程序已经众所周知，例如：

PORT = 8011
