Python 在SocketServer中处理来自（'；127.0.0.1'；xxxx）的请求时发生异常

我基于SimpleHTTPServer和SocketServer编写了一个预览函数，当我输入

Ctrl-C

停止服务器时，我捕捉到

KeyboardInterrupt

异常：

#!/usr/bin/env python
# -*- coding: utf-8 -*- 
import sys 
import SimpleHTTPServer 
import SocketServer

class Reuse_TCPServer(SocketServer.TCPServer):
    timeout = 1
    allow_reuse_address = True

def preview(port=8000):
    try:
        Handler = SimpleHTTPServer.SimpleHTTPRequestHandler
        httpd = Reuse_TCPServer(("", port), Handler)
    except OSError as e:
        print("Could not listen on port {}".format(port))
        sys.exit(getattr(e, 'exitcode', 1))

    try:
        httpd.serve_forever()
    except (KeyboardInterrupt, SystemExit) as e:
        print("Shutting down server")
        httpd.socket.close()

if __name__ == "__main__":
    preview()

但大多数情况下，如果我打开localhost:8000并立即（几秒钟）输入“Ctrl-C”，它将首先显示消息，然后关闭套接字：

127.0.0.1 - - [16/Apr/2014 22:20:42] code 404, message File not found
127.0.0.1 - - [16/Apr/2014 22:20:42] "GET /static/css/autumn.css HTTP/1.1" 404 -

有人知道如何解决这个问题吗？

我也有同样的经历。我在Python2.7中发现了一个旧的bug和一个应该解决这个问题的补丁。我检查了它，补丁当然已经在SocketServer.py中了。然而，它并没有解决这个问题。 在任何情况下，我粘贴在这里的链接中的解释都值得一读，以试图得到一个提示

您的问题是什么？@laike9m抱歉，我有更新问题：“如何解决此问题”我仍然不知道您的问题是什么您还必须多次按Ctrl-C才能使其工作？@laike9m问题是如何解决我在我的问题中粘贴的内容，消息“处理来自…的请求时发生异常”这里也一样：同样的问题，同样的挫折，同样令人讨厌的异常堵塞了我的日志文件。
