　　 SocketServer 体系由两个部分构成 BaseServer 和 BaseRequestHandler。思想很简单 BaseServer接受请求,将请求交给BaseRequestHandler处理。所以如果我们想思想自己特定的Socket服务器,只用创建自己的 MyServer 和 MyRequestHandler 分别继承自适合的BaseServer 和 BaseRequestHandler。下面我们实现一个简单的Web服务器

 1 from os import curdir, sep
 2 from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
 3 
 4 class MyHandler(BaseHTTPRequestHandler):
 5     def do_GET(self):
 6         try:
 7             f = open(curdir + sep + self.path)
 8             self.send_response(200)
 9             self.send_header('Content-type', 'text/html')
10             self.end_headers()
11             self.wfile.write(f.read)
12             f.close()
13         except ImportError:
14             self.send_error(404, 'File Not Found: %s' % self.path)
15 
16 def main():
17     try:
18         server = HTTPServer(('', 80), MyHandler)
19         print 'Welcome to the machine...........'
20         print 'Press ^C once or twice to quit.'
21         server.serve_forever()
22     except KeyboardInterrupt:
23         print '^C received, shutting down server'
24         server.socket.close()
25 
26 if __name__ == '__main__':
27     main()
