node连接mysql案例

    var express = require('express');
    var app = express();
    var mysql      = require('mysql');
    app.get('/testSql', function (req, res) {
        var connection = mysql.createConnection({
            host     : 'localhost',
            user     : 'root',
            password : 'root',
            database : 'recorder_test'
        });
        connection.connect();
        connection.query('SELECT * from job where id='+req.query.id, function (error, results, fields) {
            if (error){
                throw error;
            }
            console.log('The solution is: ', results);
            res.send(JSON.stringify(results));
        });
        connection.end();
    })


    app.get('/b', function (req, res) {
        console.log(req);
        let m = {
            name: "",
            name2: "",
        };
        m.name = "123";
        m.name2 = "456";
        let s = JSON.stringify(m);
        console.log(s);
        res.send(s);
    })

    app.get('/a', function (req, res) {
        console.log(req);
        res.send('Hello World');
    })
    var server = app.listen(8088, function () {
        var host = server.address().address
        var port = server.address().port
        console.log("应用实例，访问地址为 http://%s:%s", host, port)
    })
