vue.js - 在 Vue 路由解析之前访问 Vuex

Question

我有什么:

1. 具有需要授权的路由和公共(public)路由的路由器
2. 具有用户身份验证状态的 vuex

我想要什么:使用 axios 向服务器发送请求以检查用户的身份验证状态 before 加载应用程序(在解析路由器之前) .

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:当我在浏览器中输入 mydomain.com/acount 时(之前未加载应用程序)并获得授权，无论如何我都会重定向到 home 。重定向后，我看到我已获得授权(我在 Home 组件中设置了一些 DOM 元素，该元素仅对授权用户显示)。

我已经试过了，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，我尝试从

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。

四处走动 Vanojx1's answer ，接下来我解决了我的问题。

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()
  }
})
