VUEX 数据持久化,刷新后重新获取的例子

// store.js
 getters: {
  userInfo(state) {
   console.log('getters',state);
   if (!state.userInfo.id) {
    let token = getStorage("token");
    console.log('token',token);
    if (token) {
     let userInfo = getStorage("userInfo");
     state.userInfo = userInfo.data;
    }
   }
   return state.userInfo
  }
 },

// component.js
userInfo() {
      return this.$store.getters.userInfo;
    }
