我有什么:
我想要什么:使用axios
向服务器发送请求,以在加载应用程序之前(在解决路由器之前)检查用户的身份验证状态 。>
router.js
:
import Vue from 'vue'
import Router from 'vue-router'
import store from './store'
Vue.use(Router)
const router = new Router({
...
routes: [
{
path: '/',
name: 'home',
component: Home
},
{
path: '/account',
name: 'account',
component: () => import(/* webpackChunkName: "account" */ './views/Account.vue'),
meta: {
requiresAuth: true
}
}
]
})
router.beforeEach((to, from, next) => {
if (to.matched.some(route => route.meta.requiresAuth)) {
if (store.state.authStatus)
next()
else
next({name: 'home'})
} else {
next()
}
})
export default router
store.js
:
import Vue from 'vue'
import Vuex from 'vuex'
import axios from 'axios'
Vue.use(Vuex)
const store = new Vuex.Store({
state: {
authStatus: false
},
mutations: {
setAuthStatus(state, authStatus) {
state.authStatus = authStatus
}
}
})
axios.get(...)
.then(response => {
store.commit('setAuthStatus', true)
})
export default store
main.js
:
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
new Vue({
router,
store,
render: h => h(App)
}).$mount('#app')
我的问题:当我获得授权时在浏览器中输入mydomain.com/acount
(之前未加载应用)时,无论如何,我都重定向到了home
。重定向后,我看到我已被授权(我在Home组件内设置了一些DOM元素,仅向授权用户显示)。
我尝试过,没有帮助:
store.js
:
const store = new Vuex.Store({
...
actions: {
setAuthStatus({commit}) {
axios.get(...)
.then(response => {
commit('setAuthStatus', true)
})
}
}
})
main.js
:
store.dispatch('setAuthStatus').then(() => {
new Vue({
router,
store,
render: h => h(App)
}).$mount('#app')
})
编辑:在main.js
中,我尝试通过
new Vue({
router,
store,
render: h => h(App)
}).$mount('#app')
到
new Vue({
store,
router,
render: h => h(App)
}).$mount('#app')
它也没有帮助。

在导航卫士中,您需要异步的内容,因此将axios Promise保存为authStatus在商店中。解决提交问题并设置登录状态时。 在导航卫士中,等待承诺得到解决,然后调用下一个函数以输入下一个路由器。
Store.js
import Vue from "vue";
import Vuex from "vuex";
Vue.use(Vuex);
const store = new Vuex.Store({
state: {
/* EXAMPLE
authStatus: new Promise(resolve => {
setTimeout(() => {
const requestResult = true;
store.commit("setAuthStatus", requestResult);
resolve(requestResult);
}, 1000);
}),
*/
authStatus: axios.get(...).then((requestResult) => {
store.commit("setAuthStatus", requestResult);
}),
loggedIn: false
},
mutations: {
setAuthStatus(state, loggedIn) {
state.loggedIn = loggedIn;
}
}
});
export default store;
router.js
router.beforeEach((to, from, next) => {
if (to.matched.some(route => route.meta.requiresAuth)) {
store.state.authStatus.then(loggedIn => {
if (loggedIn) next();
else next({ name: "home" });
});
} else {
next();
}
});

绕着Vanojx1's answer,我用下一个解决了我的问题。
store.js
:
const store = new Vuex.Store({
state: {
authStatus: axios.get(...).then(response => {
store.commit('setAuthStatus', true)
}),
userAuth: false
},
mutations: {
setAuthStatus(state, authStatus) {
state.userAuth = authStatus
}
}
})
router.js
:
router.beforeEach((to, from, next) => {
if (to.matched.some(route => route.meta.requiresAuth)) {
store.state.authStatus.then(() => {
//we're getting 200 status code response here, so user is authorized
//be sure that API you're consuming return correct status code when user is authorized
next()
}).catch(() => {
//we're getting anything but not 200 status code response here, so user is not authorized
next({name: 'home'})
})
} else {
next()
}
})

问题可能是由于您输入网址时 https://example.com/account
它启动应用程序,并且axios对服务器执行异步请求。 因此,也许您应该尝试从beforeEach内部进行axios调用。
通过这种方式,您可以轻松验证用户身份。
问题是您无法使axios同步,因此必须与axios返回一个promise才能实现功能。
请告诉您这是否对您有帮助。
