Question

//所以我在节点和表达框架中使用mysql，第一次创建测试示例时一切正常。但后来我尝试创建第二个项目，现在路由似乎没有被读取。

我得到的回复是：

  [nodemon] restarting due to changes...
  [nodemon] starting `node app.js`
  Server started on port 8000
  mysql connected...

//我也应该得到结果：

OkPackege {... ... ... ... }

//But I am not getting it. Any Ideas...? thanks.

我的口述如下：

const express = require('express');
const mysql = require('mysql');

const db = mysql.createConnection({
  host      : 'localhost',
  user      : 'root',
  password  : 'LEoking1987'
  //database  : 'nodesql'
});

db.connect((err) => {
  if(err){
      throw err;
  }
  console.log('mysql connected...');
});

const app = express();

// Creates satabase if it does not exist yet.
app.get('/createdb',(req,res) => {
    let sql = 'CREATE DATABASE nodesql';
    db.query(sql, (err, result) => {
      if(err) throw err;
      console.log(result);
      res.send('Database created...');
    });
});

app.listen('8000',()=>{
  console.log('Server started on port 8000');
});

Answer 1

在你的mysql连接中添加debug：true，如

  mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: 'LEoking1987'
  database: 'nodesql'
  debug: true,     
})

使用node.js和mysql进行Woking
