Json-server + mockjs模拟假数据

本文主要是介绍Json-server + mockjs模拟假数据，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

鉴于这个代码开源出去感觉会被打，还是写个博客吧。

其实操作很简单，只要把文件读取，通过mock转化，再导出文件，然后在json-server填写相应路径即可。

源文件test.json

{"list|1-10": [{"id|+1": 1}],"user": {"name": "@name","id": "@id"}
}

通过mockjs处理

const Mock = require('mockjs');
const fs = require("fs");let data = fs.readFileSync("test.json", "utf-8");data = data.toString();
data = JSON.parse(data)
data = Mock.mock(data);
data = JSON.stringify(data);fs.writeFile('res.json', data, function(err){if(err){console.error(err);}
})

得{"list":[{"id":1},{"id":2},{"id":3}],"user":{"name":"John Martinez","id":"320000199809111043"}}

完整json-server配置文件


// server.js
const path = require('path');
const fs = require("fs");
const Mock = require('mockjs');
const jsonServer = require('json-server')let data = fs.readFileSync("test.json", "utf-8");data = data.toString();
data = JSON.parse(data)
data = Mock.mock(data);
data = JSON.stringify(data);fs.writeFile('res.json', data, function(err) {if(err){console.error(err);}const server = jsonServer.create()const router = jsonServer.router(path.join(__dirname, 'res.json'))const middlewares = jsonServer.defaults()// Set default middlewares (logger, static, cors and no-cache)server.use(middlewares)// Add custom routes before JSON Server routerserver.get('/echo', (req, res) => {res.jsonp(req.query)})// To handle POST, PUT and PATCH you need to use a body-parser// You can use the one used by JSON Serverserver.use(jsonServer.bodyParser)server.use((req, res, next) => {if (req.method === 'POST') {req.body.createdAt = Date.now()}// Continue to JSON Server routernext()})// Use default routerserver.use(router)server.listen(3000, () => {console.log('JSON Server is running')})})
