用express搭的一个静态资源服务器

server.js(入口文件)

const express = require("express");let app = express();let allRouter = require("./router/index");app.use(express.static("./"));app.use(allRouter);app.listen(2000, () => {       console.log("服务器开启");})

router/index.js(主路由)

const express = require("express");let router = express.Router();let home = require("./home");router.use("/home", home);module.exports = router;

router/home.js(home路由)

const express = require("express");const bodyParser = require("body-parser");let query = require("../db/index");let urlencodedParser = bodyParser.urlencoded({       extended: false});let router = express.Router();//测试数据router.get("/testData", async (req, res, next) => {       try {           var data = await query("SELECT * FROM listdata");    } catch (err) {           console.log(err);    }    let result = "";    if (data.length) {           result = {               msg: "success",            data,        }    } else {           result = {               msg: "err",        }    }    res.send(result)});module.exports = router;

db/index.js(mySql数据库)

const mysql = require("mysql");let pool = mysql.createPool({     host: "localhost",  port: "3306",  user: "root",  password: "",  database: "xfc",  multipleStatements: true,});let query = function (sql) {     return new Promise((resolve, reject) => {       pool.query(sql, (err, data) => {         if (err) {           reject(err);      } else {           resolve(data);      }    });  });};module.exports = query;
