因为和原生的交互是需要h5这边来提供meta标签的来是来判断要不要显示分享按钮，所有就需要手动设置meta标签，标题和内容
//router内的设置
{
path: '/teachers',
name: 'TDetail',
component: TDetail,
meta: {
title:"教师详情",
content: 'disable'
}
},
{
path: '/article',
name: 'Article',
component: Article,
meta: {
title: "文章详情",
content: 'disable-no'
}
},
//main.js里面的代码
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()
});
