2019-10-23 vue使用微信js-sdk转发

1 自己所踩过的坑
转发的函数需要在mounted中直接调用（即页面完成时直接调用）

   <script src="http://res2.wx.qq.com/open/js/jweixin-1.4.0.js"></script>
<script>
export default {
  mounted() {
    this.share();
  },
},
  methods: {
// 转发朋友圈
share() {
  var url = window.location.href.split("#")[0];//获取本页面的网址  原因：参与签名的网址需要截取#以前的  后台获取到的地址与前台参与签名的地址不符  导致签名不符
  let data = {
    pageUrl: url
  };
  this.$axios
    .post("后台给的获取签名等的接口", data)
    .then(({ data }) => {
      let my = this;
      wx.config({
        debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。
        appId: data.appid, // 必填，公众号的唯一标识
        timestamp: data.timestamp, // 必填，生成签名的时间戳
        nonceStr: data.noncestr, // 必填，生成签名的随机串
        signature: data.signature, // 必填，签名
        jsApiList: [
          "updateTimelineShareData",
          "onMenuShareTimeline",
          "updateAppMessageShareData",
          "onMenuShareAppMessage"
        ] // 必填，需要使用的JS接口列表
      });
    });
  wx.ready(function() {
    //需在用户可能点击分享按钮前就先调用
    wx.onMenuShareAppMessage({
      title: "123456", // 分享标题
      desc: "分享描述分享描述分享描述分享描述分享描述", // 分享描述
      link: window.location.href.split("#")[0], // 分享链接，该链接域名或路径必须与当前页面对应的公众号JS安全域名一致
      imgUrl:
