vue-router导航卫队不限制导航
访问任何页面之前,除了登录并注册;我想通过导航警卫对用户进行身份验证。 在以后,您可以看到我的Vue-Router代码。 “这里”已记录,但是之后没有在行中取消导航。如果用户未经认证,他仍然可以访问我
的路由器文件:
import { createRouter, createWebHistory } from "vue-router";
import axios from "axios";
import HomeView from "../views/HomeView.vue";
import RegisterView from "../views/RegisterView.vue";
import LoginView from "../views/LoginView.vue";
import MeHomeView from "../views/MeHomeView.vue";
const router = createRouter({
history: createWebHistory(import.meta.env.BASE_URL),
routes: [
{
path: "/",
name: "home",
component: HomeView,
},
{
path: "/register",
name: "register",
component: RegisterView,
},
{
path: "/login",
name: "login",
component: LoginView,
},
{
path: "/me",
name: "me",
component: MeHomeView,
},
],
});
router.beforeEach((to, from) => {
if(to.name !== 'login' && to.name !== 'register') {
console.log(to.name);
axios.post("http://localhost:4000/authenticate/", {accessToken: localStorage.getItem("accessToken")})
.then(message => {
console.log(message.data.code);
if(message.data.code === 200) {
} else {
console.log("here");
return false;
}
})
.catch(error => {
console.log(error);
return false;
})
}
})
export default router;
Before accessing any page, except login and register; I want to authenticate the user with Navigation Guards.
Following you can see my code for the vue-router. The "here" gets logged, but the navigation is not cancelled in the line afterwards. It is still possible that if the user is not authenticated that he can access the /me-route
my router-file:
import { createRouter, createWebHistory } from "vue-router";
import axios from "axios";
import HomeView from "../views/HomeView.vue";
import RegisterView from "../views/RegisterView.vue";
import LoginView from "../views/LoginView.vue";
import MeHomeView from "../views/MeHomeView.vue";
const router = createRouter({
history: createWebHistory(import.meta.env.BASE_URL),
routes: [
{
path: "/",
name: "home",
component: HomeView,
},
{
path: "/register",
name: "register",
component: RegisterView,
},
{
path: "/login",
name: "login",
component: LoginView,
},
{
path: "/me",
name: "me",
component: MeHomeView,
},
],
});
router.beforeEach((to, from) => {
if(to.name !== 'login' && to.name !== 'register') {
console.log(to.name);
axios.post("http://localhost:4000/authenticate/", {accessToken: localStorage.getItem("accessToken")})
.then(message => {
console.log(message.data.code);
if(message.data.code === 200) {
} else {
console.log("here");
return false;
}
})
.catch(error => {
console.log(error);
return false;
})
}
})
export default router;

导航警卫支持在VUE路由器4中的承诺。问题是承诺链被打破,
返回false
不会影响任何内容。根据经验,每个诺言都需要束缚。应该是:
可以使用
async..await
以更可读性和较少错误的方式编写相同的功能。Navigation guards support promises in Vue Router 4. The problem is that promise chain is broken, and
return false
doesn't affect anything. As a rule of thumb, each promise needs to be chained.It should be:
The same function can be written in more readable and less error-prone way with
async..await
.
