微信公共平台开发-(.net实现)4--发送图文消息

  之前说了让微信发送给关注我们的粉丝普通的文本信息,下面我们来看看如何发送图文信息,需要注意的是这里说的是,让微信发给我们,而不是我们拍个图片发给微信处理,上传图片在以后的再讲.下面是发送图文消息的函数,涉及title(标题),description(摘要),picurl(图片),链接 (url)几个关键的参数:

格式如下:(此为多图文形式)

其实格式呢就和上篇http://www.cnblogs.com/QLJ1314/p/3855371.html格式一样。

写了这么多了,相信你也能照葫芦画瓢接着往下进行回复语音消息、视频、音乐消息喽,或者是再深一点的,相信自己,一定能成功,可以大胆尝试一下。
