        #第三种方式(获取UTF-8编码)
        username = bottle.request.query.username      # The same string correctly re-encoded as utf8 by bottle
        password = bottle.request.query.password      # The same string correctly re-encoded as utf8 by bottle
       
        if check_login(username, password):
            return "<p>登录成功</p>"
        else:
            return "<p>登陆失败，用户名或者密码错误</p>"
    else:
        return ''' <form action="/login" method="get">
                     Username: <input name="username" type="text" />
                     Password: <input name="password" type="password" />
                     <input value="Login" name="do_submit" type="submit">
                   </form>
                '''

bottle.run(host='localhost', port=8083)

运行这个py程序后，浏览器输入：http://localhost:8083/login ， 输入用户名和密码，点击登录

        return "<p> 登录失败 </p>"

bottle.run(host='localhost', port=8083)


运行这个py程序后，浏览器输入：http://localhost:8083/login ， 输入用户名和密码，点击登录,这个明显是post请求， 而且浏览器不会显示参数
