最简单的临时web服务器

前言

有的时候需要做个单页的网页显示，这个直接用python启动即可，但是存在一个问题，停止进程以后，如果网页正在被访问，socket会不释放，然后再启动就会提示端口占用，实际上是没有端口占用的

这个增加一个配置项就行

相关代码

#!/usr/bin/python3

from __future__ import print_function

import SimpleHTTPServer
import SocketServer
import os
import sys
import signal

def quit(signal_num,frame):
    print("you stop the threading")
    sys.exit()


path = os.path.dirname(sys.argv[0])

os.chdir('/home/cephuse/output/')

class ReusingTCPServer(SimpleHTTPServer.SimpleHTTPRequestHandler):
    allow_reuse_address = True

    def send_head(self):
        # horrible kludge because SimpleHTTPServer is buggy wrt
        # slash-redirecting of requests with query arguments, and will
        # redirect to /foo?q=bar/ -- wrong slash placement
        self.path = self.path.split('?', 1)[0]
        return SimpleHTTPServer.SimpleHTTPRequestHandler.send_head(self)


SocketServer.TCPServer.allow_reuse_address = True
httpd = SocketServer.TCPServer(
    ("", 9090),
    ReusingTCPServer,
    )
try:
    print("Serving doc at port: http://localhost:9090")
    httpd.serve_forever()
except KeyboardInterrupt:
    pass

上面是参考的ceph doc的服务脚本，区别就是增加的那句

SocketServer.TCPServer.allow_reuse_address = True
