Vue 401配合Vuex防止多次弹框的案例

1.安装Vuex

npm install vuex –save

2. 新建store目录结构

3. 编辑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)
 
// 开发环境
const isDev = process.env.NODE_ENV === \'development\'
 
export default new Vuex.Store({
 strict: isDev, // 开发环境中使用严格模式，防止给Vuex的状态对象直接赋值
 state: defaultState,
 mutations,
 getters,
 actions
})

4. 编辑state.js

export default {
 tokenStatus: true, // token状态
}

5. 编辑mutations.js

export default {
 updateTokenStatus (state, bool) {
  state.tokenStatus = bool
 }
}

PS: getters用于计算属性，actions用于异步操作(暂无使用)

6. 挂载到vue根目录下，编辑main.js

import store from \'./store/store\'
 
new Vue({
 store,
 router,
 render: h => h(App)
}).$mount(\'#app\')

7. login 登录时,改变state.tokenStatus的值

import { mapMutations } from \'vuex\' 
methods: {
  // 声明Vuex的mutations的方法
  ...mapMutations([\'updateTokenStatus\']),
  // 登录方法
  login () {
    ......
    // 改变Vuex.state.tokenStatus的值
    this.updateTokenStatus(true)
  }
}

8. 配置axios的错误判断

// 初始化用户信息
  initUserInfo () {
   const p1 = this.$api.user.getUserInfo()
   p1.then(result => {
    this.data = result
    this.isEdit = false
    this.firstLoading = false
   }).catch(reason => {
    this.firstLoading = false
    this.isEdit = false
    // 目前后端是通过code为-1，返回错误信息
    if (parseInt(reason.code) === -1) {
     this.$alert(reason.message, \'提示\', { type: \'error\' })
    }
   })
  },

9. 拦截响应, 处理401，返回自定义错误

import router from \'../../router\'
import axios from \'axios\'
import localStorage from \'localStorage\'
import { MessageBox } from \'element-ui\'
import store from \'../../store/store\'
 
// http response 拦截器
axios.interceptors.response.use(
 response => {
  return response
 },
 error => {
  if (error.response) {
   if (error.response.status === 401) {
    switch (error.response.status) {
     case 401:
      const route = localStorage.getItem(\'vip_entrance\')
      router.replace({
       path: route,
       query: { redirect: router.currentRoute.fullPath }
      })
      if (store.state.tokenStatus) {
       // 饿了么框架弹框
       MessageBox.alert(\'登录超时！\', \'提示\', { type: \'error\' })
       // 修改tokenStatus状态，防止多次点击
       store.commit(\'updateTokenStatus\', false)
      }
      const data = {
       code: 1
      }
      return Promise.reject(data)
    }
   }
  }
  return Promise.reject(error.response.data)
 }
)

补充知识：vue 配置vuex在严格模式下出现是问题

我就废话不多说了，大家还是直接看代码吧~

需要关闭严格模式，不然会报错

import Vue from \"vue\";
import Vuex from \"vuex\";
import createPersistedState from \"vuex-persistedstate\";
import * as Cookies from \"js-cookie\";
import user from \"./modules/user\";
import myCen from \"./modules/myCen\";
import registered from \"./modules/registered\";
Vue.use(Vuex);

export default new Vuex.Store({
 strict: false, //关闭严格模式
 modules: {
  user,
  myCen,
  registered
 },
 // 持久化储存
 plugins: [ 
  createPersistedState({
   storage: {
    getItem: key => Cookies.get(key),
    setItem: (key, value) => Cookies.set(key, value, { expires: 7 }),
    removeItem: key => Cookies.remove(key)
   }
  })
 ]
});
