标签：vue beforeEach next path router true 路由
// isLogined 用来判断用户是否已登录
router.beforeEach((to, from, next) => {
if(isLogined){
next()
}else{
console.log('测试')
next('login')
}
})
- next() 表示放行，直接进入to路由，不会再次调用router.beforeEach()
- next(path:...to,replace:true) 拦截路由，当条件成立时就会无限次放行，进入无限循环，必须要设置出口
- next(path:'/') 当前路由被中断，进入一个新的导航 、需要加判断、不然会进入无限循环
- 可以理解为
router.beforeEach((to, from, next) => {
router.beforeEach((to, from, next) => {
router.beforeEach((to, from, next) => {
router.beforeEach((to, from, next) => {
router.beforeEach((to, from, next) => {
。。。
})
})
})
})
})
//必须要设置出口
router.beforeEach((to, from, next) => {
let flag=true
if(flag){
//条件成立，放行并进入页面
next()
}else{
//重载路由
next({path:...to,replace:true})
}
})
