我正在尝试检索网站的 IP 地址，但在第 18 行中不断收到此错误，gaierror: [Errno 11004] getaddrinfo failed"，我们将不胜感激，谢谢.

I'm trying to retrieve the IP Address of a website, but I keep getting this error, "gaierror: [Errno 11004] getaddrinfo failed" in line 18, your help will be appreciated, Thanks.

错误:

Exception in Tkinter callback

  File "C:\Python26\lib\lib-tk\Tkinter.py", line 1410, in __call__
    return self.func(*args)

    targetip = socket.gethostbyname_ex(text1.get("1.0", END))
gaierror: [Errno 11004] getaddrinfo failed

推荐答案

我的猜测是因为您使用的主机名带有尾随换行符.在我写这个答案的时候，你的代码显示:

My guess is because you are using a hostname that has a trailing newline. At the time I write this answer, your code shows:

def Info():
    targetip = socket.gethostbyname_ex(text1.get("1.0", END))
    text.insert(END, targetip)

当您使用索引 END 时，您将获得由文本小部件添加的额外换行符.您需要将其剥离或使用索引 "end-1c".

When you use the index END you get the extra newline that is added by the text widget. You need to strip that off or use the index "end-1c".
