VueX+VueRouter+Cookie实现简单登录页

路由页的登录导航守卫设置

import Cookies from 'js-cookie'

// Not login 
router.beforeEach((to, from, next) => {
  if (to.matched.some(m => m.meta.auth)) {
    // 对路由进行验证
    if (Cookies.get('userInfo')) { // 已经登陆
      next()     // 正常跳转到设置好的页面
    } else {
      // 未登录则跳转到登陆界面，query:{ Rurl: t o.fullPath}
      // 表示把当前路由信息传递过去方便登录后跳转回来；
      next({ path: '/login', query: { Rurl: to.fullPath } })
    }
  } else { next() }
})

引入js-cookie

npm i js-cookie

模块化开发时:

import Cookies from 'js-cookie'

VueX中的设置

import Vue from 'vue'
import Vuex from 'vuex'
import Cookies from 'js-cookie'

Vue.use(Vuex)

const store = new Vuex.Store({
  state: {
    userInfo:  Cookies.get('userInfo'),
    isLogin: 0,
    currentUser: ''
  },
  mutations: {
    loginSuc(state,data){
      state.userInfo=data
//缓存2小时，1msx1000=1s，1sx60=1min,1minx60x2=2hours
      var date = new Date((new Date().getTime()+120*60*1000))
      Cookies.set('userInfo',data,{expires:date})
    },
    loginOut(state) {
      state.userInfo = null
      Cookies.remove('userInfo');
    }
  }
})

export default store

　　登录页登录逻辑部分

    handleLogin() {
      var name = this.loginForm.username;
      this.$message({
        message: "欢迎 " + name + "，(*^_^*)",
        center: true,
      });
      this.$refs.loginForm.validate((valid) => {
        if (valid) {
          this.userInfo.name = name;
          this.userInfo.isLogin = "100";
          this.$store.commit("loginSuc", this.userInfo);

          const url = this.$route.query.Rurl || "/";
          this.$router.push(url);
        } else {
          console.log("error submit!!");
          return false;
        }
      });
    },

　　注：commit提交到store里一次最多提交2个，多了会报错
