先在微信公众号里面配置js接口安全域名
HTML代码部分
<script src="http://res./open/js/jweixin-1.0.0.js"></script>
<script type="text/javascript">
//if(!(/MicroMessenger/i.test(navigator.userAgent)))
//{
// document.body.innerHTML="请在微信打开此链接";
//}
// 注意：所有的JS接口只能在公众号绑定的域名下调用，公众号开发者需要先登录微信公众平台进入“公众号设置”的“功能设置”里填写“JS接口安全域名”。
// 如果发现在 Android 不能分享自定义内容，请到官网下载最新的包覆盖安装，Android 自定义分享接口需升级至 6.0.2.58 版本及以上。
// 完整 JS-SDK 文档地址：http://mp./wiki/7/aaa137b55fb2e0456bf8dd9148dd613f.html
wx.config({
debug: false,

jsApiList: [

wx.ready(function () {
// 2.2 监听“分享到朋友圈”按钮点击、自定义分享内容及分享结果接口
wx.onMenuShareTimeline({

fail: function (res) {

wx.error(function (res) {
// config信息验证失败会执行error函数，如签名过期导致验证失败，具体错误信息可以打开config的debug模式查看，也可以在返回的res参数中查看，对于SPA可以在这里更新签名。
alert("errorMSG:" + res);

注：获取的Access_Token必须是全局Access_Token不是网页的Access—_Token,全局Access_token缓存72000秒，也就是两个小时，微信端不宜频繁访问。 signature 签名每次访问都要更新，切勿保存到session里面
