This time I will bring you the precautions to determine whether the page is logged in and whether the page is logged in. The following is a practical case, let's take a look.

is as follows:

router.beforeEach((to, from, next) => {
 if (to.matched.some(record => record.meta.requireAuth)){ // 判断该路由是否需要登录权限
 if (token) { // 判断当前的token是否存在
  next();
 }
 else {
  next({
  path: '/login',
  query: {redirect: to.fullPath} // 将跳转的路由path作为参数,登录成功后跳转到该路由
  })
 }
 }
 else {
 next();
 }
});
Copy after login
Before that, add a meta

attribute to the route:

{
 path: '/index',
 meta: {
  title: '',
  requireAuth: true, // 添加该字段,表示进入这个路由是需要登录的
 },
}
Copy after login

Note: But the fact is that most of the time there is no jump when logging in, so you need to add a section to the login jump path:

if(this.$route.query.redirect){
//  let redirect = decodeURIComponent(this.$route.query.redirect);
  let redirect = this.$route.query.redirect;
  this.$router.push(redirect);
}else{
  this.$router.push('/');
 }
Copy after login
