微信公众平台接口,asp.net实现

原文: 微信公众平台接口,asp.net实现

我为自己的笑话网开发了一个微信公众平台的接口,在这里分享给大家,希望能对朋友们有帮助,如果有什么地方写的不好,好请大家指点!

首先是要进行认证,认证的时候,只需要在Page_Load事件里面单独去执行 认证的方法就可以了,具体代码见下面的RenZheng()

认证通过之后就可以对网友的消息进行处理,可以根据微信平台推送过来的数据进行分析!我相信大家在看到这篇文章的时候,在此之前肯定对平台都有所了解了,所以,废话不多说,直接上代码! 如果有什么疑问的欢迎加群:242384606 进行讨论!

                content = "/:rose欢迎关注52冷笑话/:rose\n看笑话请直接回复“x”\n无聊时候还可以找我聊聊天哦!";
                res = sendTextMessage(wx, content);
