公共方法util.js

import Vue from 'vue'
import cuModel from '@/components/cu-model.vue'
import router from '@/router'
const Model = Vue.extend(cuModel)
const oDiv = document.createElement('div')
var VM = new Model({el: oDiv}),time_model;
document.body.appendChild(VM.$el)
export default {
	jump(type,url,object){
		object = object?object:''
		switch(type){
			case 1:
				router.push({path:url,query:object});
				break;
			case 2:
				router.go(-1);
				break;
		}
	},
	model(content,createDialog){
		VM.content = content
		VM.show = true
		clearTimeout(time_model)
		time_model = setTimeout(() => {
		  VM.show = false
		}, 5000)
	},
}

配置成全局main.js

import util from '@/utils/util'
Vue.prototype.$util = util


调用方法：
this.$util.model('这是消息弹窗')//弹窗
this.$util.jump(1,路径,参数)//跳转

封装axios请求

npm安装:npm install axios --save
axios文档:https://www.kancloud.cn/yunye/axios/234845

import axios from 'axios'
import util from '@/utils/util'
export default {
	request(url, data, method, title, header) {
	  return new Promise((resove, reject) => {
		  axios({
			url: url,
			method: method.toUpperCase(),
			data: data,
			header:{
				'content-type':(header ? header :"application/json")
			}
		  }).then((res) => {
			if (res.data.code == "401") {//登录失效
				util.jump(1,'/login')
				util.model(res.data.msg)
			}else{
				resove(res.data);
			}
		  }).catch(function (error) {
			reject('fail')	
		  })
	  })
	}
}


调用方法
import http from '@/utils/httpUtil.js'//引入axios封装js

http.request(接口url,接口参数{对象格式},请求方法'post',请求header默认application/json).then((res) => {
	console.log('返回',res)
})
