基于IOS端微信分享失效的踩坑及解决方法

// 此处在main.js中，在vue-router每次改变路由的时候去调用wx.config
router.beforeEach((to, from, next) => {
 let url =`www.example.com`;
 let getCOnfig= async function(url) {
  // res为后端接口中返回的config
  const res = await get_config(url);
  wx.config(res);
  console.log(res);
 };
})
 // 此部分为微信分享
 var cOnfig= {
  title: 'title', // 分享标题
  desc: 'desc', // 分享描述
  link: 'link', // 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: `image',
  success: function() {
   console.log(success)
  },
  cancel: function() {
    console.log(failf)
  }
 };
 wx.ready(() => {
  wx.onMenuShareAppMessage(config);
  wx.onMenuShareTimeline(config);
 });

//通过userAgent判断IOS环境
 let isIOS = function() {
  var isIphOne= navigator.userAgent.includes('iPhone'）;
  var isIpad = navigator.userAgent.includes('iPad');
  return isIphone || isIpad;
 };

// 如果是IOS系统，则只在根路径初始化config
 if (isIOS()) {
  if (to.path === '/') {
   getConfig(url);
   next();
  } else {
   next();
  }
 } else {
  getConfig(url);
  next();
 }

router.beforeEach((to, from, next) => {
 let url = `*****`;
 let getCOnfig= async function(url) {
  const res = await get_config(url);
  wx.config(res);
  console.log(res);
 };
 let isIOS = function() {
  var isIphOne= navigator
   .userAgent
   .includes('iPhone');
  var isIpad = navigator
   .userAgent
   .includes('iPad');
  return isIphone || isIpad;
 };
 var cOnfig= {
  title: '*****', // 分享标题
  desc: '******', // 分享描述
  link: '***************', // 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: `*****`,
  type: 'link',
  dataUrl: '',
  success: function() {},
  cancel: function() {}
 };
 wx.ready(() => {
  wx.onMenuShareAppMessage(config);
  wx.onMenuShareTimeline(config);
 });
 if (isIOS()) {
  if (to.path === '/') {
   getConfig(url);
   next();
  } else {
   next();
  }
 } else {
  getConfig(url);
  next();
 }
});
