Question

上面有我的app.js服务器的屏幕快照，由于某种原因，连接无法通过，我下面有我的app.js代码

const express = require('express');
const app = express();
const mysql = require('mysql');
const bodyparser = require('body-parser');
app.use(bodyparser.json());

const mysqlConnection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: 'Adil@123',
  database: 'movies'

});
mysqlConnection.connect(err=>{
  if (err) {
    console.log('It was not successful \n Error:' + JSON.stringify(err,undefined,2));
  } else {
    console.log('Its a success');
  }
  });
 //  Collecting all the movies from the movielist
  app.get('/movielist',(req,res)=> {
    mysqlConnection.query("SELECT * FROM movielist", (err, rows,fields)=> {
      if (!err) {
        res.send(rows);
      } else {
        console.log(err);
      }
    });
  });
 // Finding a movie based on the `idmovielist` number
   app.get('/movielist',(req,res) => {
    mysqlConnection.query("SELECT * FROM movielist WHERE idmovielist = ?",[req.params.id],(err, rows,fields) =>{
    if (!err) {
      res.send(rows);
    } else {
    console.log(err);
    }
    });
  });

  // Delting a movie
   app.delete('/movielist/:id',(req,res) => {
    mysqlConnection.query("DELETE FROM movielist WHERE idmovielist = ?",[req.params.id],(err,rows,fields) =>{
      if (!err) {
        res.send("Movie is deleted");
      } else {
      console.log(err);
    }
    });
  });
  // Inserting a movie
  app.post('/movielist/addMovie',(req, res) => {
   mysqlConnection.query("INSERT INTO movielist (`idmovielist`,`name`,`thumnail_path`,`description`,`language_released`,`year_released`) VALUES ('"+req.body.idmovielist+"', '"+req.body.name+"','"+req.body.thumnail_path+"', '"+req.body.description+"', '"+req.body.year_released+"', '"+req.body.language_released+"' )",
   (err,rows) => {
     if (!err) {
       res.send("Movie is added");
     } else {
       console.log(err);
     }
  });
});

// Updating the movie list
app.put('/movielist/:id',(req,res) =>{
let update = req.body;
mysqlConnection.query("UPDATE movielist SET `year_released` WHERE = '"+update.idmovielist+"','"+update.year_released+"'",
(err, results)  => {
    if (!err) {
      res.send("Movie list is updated");
    } else {
      console.log(err);
    }
});
});


// localhost:3000
app.listen(3000,() => {
  console.log('We got it running');
});
module.exports = app;

上面是我的app.js，该服务器以前可以工作，但是由于某种原因它不再工作了，这可能是问题所在我的代码有问题还是应该更改端口或创建其他服务器

本地主机不成功
