1.安裝Vuex
npm install vuex --save
2. 新建store目錄結構
3. 編輯store.js

import Vuex from 'vuex'import Vue from 'vue'import defaultState from './state/state'import mutations from './mutations/mutations'import getters from './getters/getters'import actions from './actions/actions' Vue.use(Vuex) // 開發環境const isDev = process.env.NODE_ENV === 'development' export default new Vuex.Store({ strict: isDev, // 開發環境中使用嚴格模式，防止給Vuex的狀態對象直接賦值 state: defaultState, mutations, getters, actions}) |
4. 編輯state.js
|

export default { tokenStatus: true, // token狀態} |
5. 編輯mutations.js

|
export default { updateTokenStatus (state, bool) { state.tokenStatus = bool }} |
PS: getters用于計算屬性，actions用于異步操作(暫無使用)
6. 掛載到vue根目錄下，編輯main.js

import store from './store/store' new Vue({ store, router, render: h => h(App)}).$mount('#app') |
7. login 登錄時,改變state.tokenStatus的值

import { mapMutations } from 'vuex'methods: { // 聲明Vuex的mutations的方法 ...mapMutations(['updateTokenStatus']), // 登錄方法 login () { ...... // 改變Vuex.state.tokenStatus的值 this.updateTokenStatus(true) }} |
8. 配置axios的錯誤判斷

// 初始化用戶信息 initUserInfo () { const p1 = this.$api.user.getUserInfo() p1.then(result => { this.data = result this.isEdit = false this.firstLoading = false }).catch(reason => { this.firstLoading = false this.isEdit = false // 目前后端是通過code為-1，返回錯誤信息 if (parseInt(reason.code) === -1) { this.$alert(reason.message, '提示', { type: 'error' }) } }) }, |
9. 攔截響應, 處理401，返回自定義錯誤

補充知識：vue 配置vuex在嚴格模式下出現是問題
我就廢話不多說了，大家還是直接看代碼吧~
需要關閉嚴格模式，不然會報錯

以上這篇Vue 401配合Vuex防止多次彈框的案例就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持服務器之家。
