JavaScript-WeChat share forwarded to a friend, description is URL

Hopefully the result is this:

Now we have a self-adapting page, and the result is that when you turn this page forward to a friend, the title is displayed, but the picture and description are not displayed.

The online solution says:
The picture is larger than 300x300 and is the first one. But I can't guarantee that there are pictures in the content. So prepare the content without a picture, replace it with a default picture.

The description will be read as long as there is content in the meta description of the page. As below, no use.

Requires JSSDK, requires a small back-end partner to match

  wx.ready(function () {                       // 获取“分享到朋友圈”按钮点击状态及自定义分享内容接口                    wx.onMenuShareTimeline({                        title: "title", // 分享标题                        link:"url",                        imgUrl: "sharePic.jpg", // 分享图标                        success: function (res) {                        }                    });                                            // 获取“分享给朋友”按钮点击状态及自定义分享内容接口                    wx.onMenuShareAppMessage({                        title: "title", // 分享标题                        link:"url",                        imgUrl: "sharePic.jpg", // 分享图标                        desc: '描述', // 分享描述                        type: 'link', // 分享类型,music、video或link，不填默认为link                        success: function (res) {                        }                    });  });

Need to load Jweixin.js
The URL is as follows:
Http://qydev.weixin.qq.com/wiki/index.php?title=%E5%BE%AE%E4%BF%A1JS%E6%8E%A5%E5%8F%A3

Then call the share API below to share, the other ibid. I'm so lazy.
