当在tk命令中使用套接字函数时'WinError 10061'

Question

嗨，感谢您阅读本文。我知道什么问题是，但我无法弄清楚如何解决它。

所以，问题是这样的（我认为），蟒蛇正试图运行connect()用户输入主机名（hostname）之前，因此蟒蛇试图连接到一个空白的主机（''），这又导致[WinError 10061]即将发生。我试图用另一个函数（connect_buffer()）缓冲connect()，即使当我添加一个if语句，将hostname设置为'localhost'，如果hostname为空（''），但错误仍然不存在，并且出现错误错误。

所以我的问题是我该如何解决这个问题？

以下是错误：

Traceback (most recent call last): 
    File "H:\server\New folder\Tk_cleint.py", line 89, in <module> 
    setup_confirm_button = tk.Button(window,text = 'Connect', command = setup()) 
    File "H:\server\New folder\Tk_cleint.py", line 18, in setup 
    create_sock(host, int(port)) 
    File "H:\server\New folder\Tk_cleint.py", line 36, in create_sock 
    connect(cleintsocket, nhost, nport) 
    File "H:\server\New folder\Tk_cleint.py", line 27, in connect 
    self.connect((hostname, connectingport))

谢谢任何​​人的帮助。

在您setup_confirm_button你使用command = setup()这应该是command = setup或command = lambda: setup()

通过调用setup()你实际上调用该函数，而不是将其设置为以该命令的函数的引用，并且它的运行您的功能，而不是点击按钮。

使用lambda: setup()的原因也适用，因为lambda创建了一个匿名函数。

此外，在你的多处理过程中，你同样调用resv()而不是通过resv这是用while循环调用函数并阻塞主事件循环。
