微信开发之大转盘功能
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，而微信大转盘就是其中最为常见的活动。
下面详细介绍：一、使用1. 新建一个大转盘的活动：
2. 奖项设置
3. 保存后，在微信里给公众号发一个“大转盘”的消息， 就会收到大转盘的内容
4. 点击进入大转盘活动，然后点击中间的 “点击抽奖”：
二、实现1. 页面1.1 前台代码<% if (ErrLevel < 100){Response.Write(ErrorInfo);}else if (ErrLevel == 101){//活动已结束，跳转到结束页面%><script type="text/javascript">window.location.href = "end.aspx?wid="+<%=wid%>+"&aid="+<%=aid%>+"&openid="+<%=openid%>+";";</script><%}else{%><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head id="Head1" runat="server"><meta http-equiv="Content-Type" content="text/html;
