本文介绍了vue 模拟后台数据（加载本地json文件）调试，分享给大家，也给自己留个笔记

首先创建一个本地json文件，放在项目中如下

{
 "runRedLight":{
  "CurrentPage": 1,
  "TotalPages": 0,
  "TotalItems": 0,
  "ItemsPerPage": 100,
  "Items":[
   {"DEVICEID":"121212","DEVICETYPE":"1","DEVICETIME":"2016-10-10","CREATEDTIME": "2016-10-11"},
   {"DEVICEID":"124412","DEVICETYPE":"1","DEVICETIME":"2016-10-10","CREATEDTIME": "2016-10-11"},
   {"DEVICEID":"121255","DEVICETYPE":"1","DEVICETIME":"2016-10-10","CREATEDTIME": "2016-10-11"},
   {"DEVICEID":"121266","DEVICETYPE":"1","DEVICETIME":"2016-10-10","CREATEDTIME": "2016-10-11"}
  ]
 },
 "redLightRoad": [
  {"CREATEDTIME":"2017-03-03 09:41:44","DEVICEID":"2","ID":"45afdc60f33443d28fe0171d0df40d14","NAME":"1"},
  {"CREATEDTIME":"2017-03-03 09:41:52","DEVICEID":"5","ID":"74cf7106f1fa406f9c32ad351e7dfc76","NAME":"2"}
 ]
}

然后在dev-server.js中配置

1.数据读取

var appData = require('../data.json')；
var runRedLight = appData.runRedLight;
var redLightRoad = appData.redLightRoad;

2.定义路由

var apiRoute = express.Router();

apiRoute.get('/runRedLight',function(req, res){
 res.json({
  errno:0,//错误码
  data: runRedLight//具体数据
 })
})

apiRoute.get('/redLightRoad',function(req, res){
 res.json({
  errno:0,
  data: runRedLight
 })
})

3.注册定义的api

app.use('/api',apiRoute);

4.在页面使用url

 this.$http.get("/api/runRedLight").then((response) => {
     response = response.body;
     console.log(response.data);//需要这样获取到数组
   });

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
