因為和原生的互動是需要h5這邊來提供meta标簽的來是來判斷要不要顯示分享按鈕，所有就需要手動設定meta标簽，标題和内容
//router内的設定
{
path: '/teachers',
name: 'TDetail',
component: TDetail,
meta: {
title:"教師詳情",
content: 'disable'
}
},
{
path: '/article',
name: 'Article',
component: Article,
meta: {
title: "文章詳情",
content: 'disable-no'
}
},
//main.js裡面的代碼
router.beforeEach((to, from, next) => {
if(to.meta.content){
let head = document.getElementsByTagName('head');
let meta = document.createElement('meta');
meta.content = to.meta.content;
head[0].appendChild(meta)
}
if (to.meta.title) {
document.title = to.meta.title;
}
next()
});
