用c#开发微信 (16) 微活动 2 刮刮卡
微信营销是一种新型的营销模式，由于微信更重视用户之间的互动，故而这种营销推广不不能盲目地套用微博营销的单纯大量广告推送方式。这种方式在微信营销中的效果非常差，会令用户反感，继而取消去企业或商家的微信公众账号关注。对于企业来说，做微信推广重要的一个方面就是提高用户和公众账号之间的黏度，而微信刮刮卡就是其中最为常见的活动。
下面详细介绍：
一、使用
1. 新建
2. 奖项设置
3. 测试
保存后，给公众号发一个“刮刮卡”的消息， 就会收到刮刮卡的内容，进入活动后，就可以刮奖了
二、实现
1. 页面

这里用到了wScratchPad.js, wScratchPad是jQuery上的一个插件，它能模拟出刮的行为，使你能“擦去”一层覆盖物，这层覆盖物既可是一个图片，也可以是某种颜色涂层。
