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>
