全域路由守衛
import Vue from "vue";
import VueRouter from "vue-router";
Vue.use(VueRouter);
//路由表
const routes = [
// 重定向定的是Home頁面
{
path: "/",
redirect: "/Home"
},
{
path: "/Login",
name: "Login",
component: () => import("@/components/Login.vue") //對應的組件模板
},
{
path: "/Home", //鏈接路徑
name: "Home",
component: () => import("@/components/Home.vue") //對應的組件模板
}
];
const router = new VueRouter({
routes //路由表 必寫的
});
//路由守衛
router.beforeEach((to, form, next) => {
const nextRoute = ["Home"];
// const auth = store.state.auth;
// console.log(to.name);
//未登錄
if (nextRoute.indexOf(to.name) >= 0) {
//未登錄
// console.log(localStorage.getItem("name"));
let name = localStorage.getItem("name");
if (name == null) {
router.push({ name: "Login" });
}
}
// 已登錄狀態；當路由到login時，跳轉至home
if (to.name === "Login") {
let name = localStorage.getItem("name");
if (name != null) {
router.push({ name: "Home" });
}
}
next();
});
//匯出router
export default router;
組件守衛
beforeRouteEnter：進入組件時
beforeRouteUpdate：路由不變，傳遞的引數改變
beforeRouteLeave： 離開組件前
//進入該路由時判斷如果有token 如果沒有token，轉到登錄頁面
beforeRouteEnter:(to,from,next)=>{
var tokens=getCookie("token");
if(tokens.length>0){
next()
}else{
alert("請您先登錄")
next('/login')
}
},
路由獨享守衛
const router = new VueRouter({
routes: [
{
path: '/foo',
component: Foo,
beforeEnter: (to, from, next) => {
// 引數用法什么的都一樣,呼叫順序在全域前置守衛后面，所以不會被全域守衛覆寫
// ...
}
}
]
})
