OSError：[WinError 10049]请求的地址在其上下文Python代码中无效

Question

我正在尝试连接到一个 IP 并监听该端口。我不断收到此错误消息

OSError: [WinError 10049] The requested address is not valid in its context

当我使用本地 IP(127.0.0.1) 时它可以工作，为什么现在不能工作？我还可以 ping 通我想要访问的 IP 和端口。这是完整的错误消息。

我尝试使用 telnet ping ip 和端口，一切似乎都很好。

我认为您正在混合服务器和客户端连接。如果您想作为服务器接受连接，则可以在 0.0.0.0 处绑定，例如在服务器套接字上。与外部服务器连接只需要对方的地址 – 一个板球运动员 4 月 18 日 12:53 发表评论
