微信分享的标题、缩略图、连接及描述该如何设置，使用微信分享过程中会遇到这个情况，无解的朋友可以看看下面的代码

<script> var imgUrl = 'http://topic.xcar.com.cn/201403/ad_q3/pic/banner.jpg'; var lineLink = 'http://topic.xcar.com.cn/201403/ad_q3/index.php'; var descContent = "http://topic.xcar.com.cn/201403/ad_q3/index.php"; var shareTitle = '【奥迪Q3开启尊享礼遇季】报名试驾，赢取精美礼品'; var appid = 'wxc9937e3a66af6dc8'; function shareFriend() { WeixinJSBridge.invoke('sendAppMessage',{ "appid": appid, "img_url": imgUrl, "img_width": "640", "img_height": "640", "link": lineLink, "desc": descContent, "title": shareTitle }, function(res) { _report('send_msg', res.err_msg); }) } function shareTimeline() { WeixinJSBridge.invoke('shareTimeline',{ "img_url": imgUrl, "img_width": "640", "img_height": "640", "link": lineLink, "desc": descContent, "title": shareTitle }, function(res) { _report('timeline', res.err_msg); }); } function shareWeibo() { WeixinJSBridge.invoke('shareWeibo',{ "content": descContent, "url": lineLink, }, function(res) { _report('weibo', res.err_msg); }); } // 当微信内置浏览器完成内部初始化后会触发WeixinJSBridgeReady事件。 document.addEventListener('WeixinJSBridgeReady', function onBridgeReady() { // 发送给好友 WeixinJSBridge.on('menu:share:appmessage', function(argv){ shareFriend(); }); // 分享到朋友圈 WeixinJSBridge.on('menu:share:timeline', function(argv){ shareTimeline(); }); // 分享到微博 WeixinJSBridge.on('menu:share:weibo', function(argv){ shareWeibo(); }); }, false); </script>
