python实现http-pingserver

环境：python2.7
平时经常要测试http端口网络是否畅通，centos7的服务器系统一般都带有python2的环境，写了一个基于python2的http协议的ping服务器。

import json
import sys
import urllib
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer


class HttpHandler(BaseHTTPRequestHandler):
    def _response(self, path, args):
        code = 200
        rtv = {'path': path,
               'args': args,
               'message': 'pong'}
        rtv = json.dumps(rtv, ensure_ascii=False)
        self.send_response(code)
        self.send_header('Content-type', 'text/json; charset=utf-8')
        self.send_header('Access-Control-Allow-Origin', '*')
        self.end_headers()
        self.wfile.write(rtv.encode())

    def do_GET(self):
        path, args = urllib.splitquery(self.path)
        self._response(path, args)

    def do_POST(self):
        args = self.rfile.read(int(self.headers['content-length'])).decode("utf-8")
        self._response(self.path, args)


port = 8081
if sys.argv.__len__() > 0:
    port = sys.argv[1]
    port = int(port)
httpd = HTTPServer(('0.0.0.0', port), HttpHandler)
httpd.serve_forever()

使用方法：
将代码保存到pingServer.py文件中，使用下面的命令开启服务.

python pingServer.py 80
