if (window.localStorage.getItem(authToken)) {
store.commit(types.SETLOANNUMBER, window.localStorage.getItem('loanNumber'));
} 

npm install vue-cookie --save

import Vue from 'vue';
import Vuex from 'vuex';

Vue.use(Vuex)
var VueCookie = require('vue-cookie');

export default new Vuex.Store({
state: {
 token: VueCookie.get('token')
},
mutations: {
 saveToken(state, token) {
  state.token = token;
  // 设置存储
  VueCookie.set('token', token, { expires: '30s' });
 }
},
actions: {

}
}) 

import { mapMutations } from 'vuex';
export default {
methods: {
 login() {
  this.saveToken('123')
