vue this.$router.go(-1);返回时如何带参数

import Vue from 'vue'
 
/**
 * 定义空的vue实例，作为 eventbus实现非父子组件之间的通信(vue2.x中去掉了broadcast)
 */
var eventBus = new Vue({});
export default eventBus;

 import eventBus from '../../../static/js/eventbus.js';
  
 //返回
        back(info){
          //传递一个map，addressInfo是key，info是value
          eventBus.$emit('addressInfo',info);
          //调用router回退页面
          this.$router.go(-1);
        },

 import eventBus from '../../../static/js/eventbus.js';
 
 activated(){
      //根据key名获取传递回来的参数，data就是map
      eventBus.$on('addressInfo', function(data){
        console.log(data,"data");
      }.bind(this));
    },
