C# 微信开发-----微信会员卡（一）

这是微信的官方文档：https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1451025283,能看懂的朋友就请不要往下看了，我是看不懂的。我通过网上找到的资料来进行开发的；

第一步：先看官方文档的接口是怎么说的

这是重点，微信的都是以这种方式来请求的

HTTP请求方式: POSTURL:https://api.weixin.qq.com/card/create?access_token=ACCESS_TOKEN

其次就是拼接他的POST数据很长一篇

POST数据示例：

        "card_type": "MEMBER_CARD",
        "member_card": {

看着头大了都，有没得Demo。所以网上找的资料直接使用。

我是使用的一般处理程序文件来创建的

具体代码会贴出来
