Vue 401配合Vuex防止多次弹框的案例
时间：2021-10-09 08:52:05|栏目：vue|点击： 次
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)
}
})
]
});
