页面不会停止加载python套接字+错误索引错误：列出索引超出范围

Question

我想为多客户端套接字程序编写代码，首先我得到了Bad文件描述符，并像在这个问题中对我说的那样修复了它：套接字错误[Erno 9]错误的文件描述符HTTP服务器但现在页面不会停止加载，我得到了这个错误：

Traceback (most recent call last):
  File "C:UsersEdenDesktopHTTPserverserverV2.py", line 26, in clientthread
    FileName = rqst.split(" ")[1]
IndexError: list index out of range

我真的不知道该怎么修我认为这两个问题相互关联

rqst变量中没有空格。可能发生的情况是rqst是一个空字符串，您专门处理它，然后继续处理请求，就好像它是有效的一样。在第一个if中添加一个continue语句可以解决这个问题。
