详解vue 模拟后台数据（加载本地json文件）调试

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 });
