SocketServer处理请求时发生异常('127.0.0.1', xxxx)
我写了一个预览功能，基于SimpleHTTPServer和SocketServer。当我按下Ctrl-C来停止服务器时，我会捕捉到KeyboardInterrupt这个异常：
#!/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()
但是大多数情况下，如果我打开localhost:8000，然后立刻（几秒钟后）按'Ctrl-C'，它会先显示消息，然后再关闭连接：
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 -

有没有人知道怎么解决这个问题？

我遇到的情况和你完全一样。我发现了Python 2.7中的一个旧bug，还有一个本来应该解决这个问题的补丁。我检查了一下，发现这个补丁已经在SocketServer.py里面了。不过，这个补丁并没有解决我的问题。
无论如何，我在这里贴的链接里的解释值得一读，也许能给你一些线索。
