Python：无法连接到服务器

Question

我无法连接到服务器，它会打印出

“正在连接到端口...”，然后它只会说“套接字超时”。

我的计划将于明天到期，如果能真正发挥作用那就太好了。

编辑代码：现在它将仅使用连接到端口... 没有打印任何其他内容。

旁注：不存在错误。 非常感谢。另外我才刚刚学习，别喷我。 :(

EDIT2：我已经解决了大部分问题，但现在收到错误：

Answer 1

看来你从来没有将连接信息传递到套接字：

                self.irc = socket.socket()

我认为它应该是这样的：

                self.irc = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
                self.irc.connect((self.server, self.port))

Answer 2

在 iConnect 中，您只是创建一个套接字，而不是将其连接到服务器。您需要使用 socket.create_connection。
此外，将 socket.error 和 socket.timeout 混在一起并不是一个好主意，因为它在调试时可能会产生误导。另外，您应该打印错误，而不仅仅是一般消息。它将帮助您找出问题所在。

Answer 3

您不会在任何地方调用 iStart。如果我没记错我的 IRC，您需要先发送您的昵称信息，然后它才会向您发送任何数据。
