1.安装Vuex
npm install vuex --save
npm install vuex --save2. 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
})
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
}
export default {
tokenStatus: true, // token状态
}5. 编辑mutations.js
export default {
updateTokenStatus (state, bool) {

state.tokenStatus = bool
}
}
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')
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)

}
}
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' })

}

})

},
// 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)
}
)
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补充知识：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)

}

})
]
});


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({

removeItem: key => Cookies.remove(key)

}

})
]
});

以上这篇Vue 401配合Vuex防止多次弹框的案例就是小编分享给大家的全部内容了，希望能给大家一个参考。
