Node+express+mysql实现后台服务接口

next()
})

// exports.app
module.exports = app

**2. 模拟数据。这里先采用构造json数据结构的方式，resultData.js代码如下：**

const express = require(‘express’)
const app = express()

// 设置跨域
app.all(‘', (req, res, next) => {
res.header(‘Access-Control-Allow-Origin’, '’)
res.header(‘Access-Control-Allow-Headers’, ‘X-Requested-With’)
res.header(‘Access-Control-Allow-Methods’, ‘PUT,POST,GET,DELETE,OPTIONS’)
res.header(‘X-Powered-By’, ‘3.2.1’)
res.header(‘Content-type’, ‘application/json;charset=utf-8’)
next()
})

// exports.app
module.exports = app

**3. 写接口。server1.js代码如下**

const app1 = require(‘./http’)
const res1 = require(‘./data’)
console.log(app1)
// 接口1
app1.get(‘/getTest1’, (req, res) => {
res.status(200)
res.json(res
