nodejs 接口传输数据

本文主要是介绍nodejs 接口传输数据，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！

最近项目需要接口传输，于是乎找了那个选择哪个语言，选择node,而且是https模式！
找了好久才解决跨域问题！废话不多说，直接上代码

let mysql = require('mysql');
let express = require('express');
let app = express();
let https = require("https");
let fs = require("fs");
// Configuare https
const httpsOption = {key : fs.readFileSync("./https/3_jdong.xuexuebang.cn.key"),//https证书keycert: fs.readFileSync("./https/2_jdong.xuexuebang.cn.crt")//https证书crt
}
//链接数据库
let connection = mysql.createConnection({host     : '127.0.0.1',port     : '3306',database : 'sz',user     : 'soubei',password : 'soubei',
})connection.connect();//解决跨域问题
app.all("*",function (req, res, next) { //允许所有请求方式res.header("Access-Control-Allow-Origin","*");//所有res.header("Access-Control-Allow-Headers","content-type")//postnext()
})app.get('/userlist',function(req,res){shop_name = req.query.shop_name;connection.query('SELECT * from `order` where orderStatus="暂停" ',function(error,results,fileds){if(error) throw error;res.header("Access-Control-Allow-Origin", "*");res.header('Access-Control-Allow-Headers', 'Content-type');res.header("Access-Control-Allow-Methods", "PUT,POST,GET,DELETE,OPTIONS,PATCH");res.header('Access-Control-Max-Age',1728000);//预请求缓存20天res.writeHead(200,{"Content-Type":"text/json;chartset=utf-8"})data = []// console.log('SELECT skuId from `cmf_order_sku` where shop_name="'+shop_name+'" group by skuId')connection.query('SELECT skuId from `cmf_order_sku` where shop_name="'+shop_name+'" group by skuId',function(error,result,fileds){if (result !=''){res.end(JSON.stringify(result))}if (error == null){res.end(JSON.stringify('请求失败'))}})})
})https.createServer(httpsOption, app).listen(8080,function(){// let host = server.address().address;// let port = server.address().port;console.log("应用实例，运行在http://%s:%s")
});
