vue中路由验证和相应拦截的使用详解

import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
 state: {
 user: false
 },
 mutations: {
 // 登录
 login (state, user) {
  state.user = user
 },
 // 退出
 logout (state, user) {
  state.user = false
 }
 }
})

if (!store.state.user && (to.path === '/watchHouse' || to.path === '/AgentMsg')) {
 next({ path: '/login' })
}

if (!store.state.user && (from.path === '/my') && (to.path === '/ToolCompute')) {
 next({ path: '/login' })
}

router.beforeEach((to, from, next) => {
 if (to.path === '/login') {
 next()
 } else {
 if (!store.state.user && (to.path === '/watchHouse' || to.path === '/AgentMsg')) {
  next({ path: '/login' })
 } else {
  next()
 }
 if (!store.state.user && (from.path === '/my') && (to.path === '/ToolCompute')) {
  next({ path: '/login' })
 }
 }
})

var app=new Vue({
 el: '#app',
 router,
 store,
 created(){
 checkLogin().then(function (res) {
  if(res.data&&res.data.code==1){
  store.commit('login',true);
  }
  else{
  router.push('/watchHouse-css');
  }
 })
 },
 template: '<App/>',
 components: { App }
})


//响应拦截器
axios.interceptors.response.use(function(res){
 //如果是未登录
 if(res.data&&res.data.code==2){
 app.$alert('登录用户已超时，请重新登录', '提示', {
  confirmButtonText: '确定',
  type:'warning',
  closeOnClickModal:false,
  callback: action => {
  router.push('/watchHouse-css')
  }
 });
 }
 return res;
},function(err){
 return Promise.reject(err);
})
