python为tornado添加recaptcha验证码功能

复制代码 代码如下:
    from urllib.request import urlopen
    from urllib.parse import urlencode
    import tornado.httpserver
    import tornado.ioloop
    import tornado.web

   
    #获取key: https://www.google.com/recaptcha/whyrecaptcha
    publickey = \’填入你的 public key\’
    privatekey = \’填入你的 private key\’

   
    class Application(tornado.web.Application):
        def __init__(self):
            handlers = [
                (r\’/\’, IndexHandler)
            ]
            settings = dict(
                template_path=\”templates\”,
            )

            tornado.web.Application.__init__(self, handlers, **settings)

   
    class IndexHandler(tornado.web.RequestHandler):
        def get(self):
            self.render(\’index.html\’, publickey=publickey)

        def post(self):
            url = \’http://www.google.com/recaptcha/api/verify\’

            #验证码
            challenge = self.get_argument(\’recaptcha_challenge_field\’)
            #用户输入
            response = self.get_argument(\’recaptcha_response_field\’)

            data = {
                \’privatekey\’: privatekey,
                \’remoteip\’: self.request.remote_ip,
                \’challenge\’: challenge,
                \’response\’: response
            }

            res = urlopen(url, data=urlencode(data).encode())
            #获取验证结果，这里直接将返回结果输出到页面
            self.write(res.read().decode())

   
    if __name__ == \’__main__\’:
        server = tornado.httpserver.HTTPServer(Application())
        server.listen(10001)
        tornado.ioloop.IOLoop.instance().start()
