详解vue 模拟后台数据（加载本地json文件）调试

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
   });
