代码如下：

import SimpleHTTPServerimport SocketServerimport redef htc(m):    return chr(int(m.group(1),16))def urldecode(url):    rex=re.compile('%([0-9a-hA-H][0-9a-hA-H])',re.M)    return rex.sub(htc,url)class SETHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):    def createHTML(self):        html = file("index.html", "r")        for line in html:            self.wfile.write(line)                def do_GET(self):        print "GET"        print self.headers;        self.createHTML()            def do_POST(self):        print "POST"        print self.headers;        length = int(self.headers.getheader('content-length'))        qs = self.rfile.read(length)        url=urldecode(qs)        print "url="        print url        self.createHTML()        Handler = SETHandlerPORT = 8000httpd = SocketServer.TCPServer(("", PORT), Handler)print "serving at port", PORThttpd.serve_forever()

测试用的index.html页面如下：

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Insert title here</title></head><body><form action="http://127.0.0.1:8000/" method="post">username:<input type="text" name="username"><br>password:<input type="password" name="password"><br> <input type="submit" value="login"></form></body></html>

在浏览器里打开http://127.0.0.1:8000/，输出如下：

点击"login"后，输入如下：
