如何在cpanel中设置连接mysql db的节点js服务器

我是一个新手,试图在cpanel中启动一个仅连接到mysql数据库的节点js服务器,但是当我包含mysql位时,它们将被完全忽略,没有任何错误或完全引用mysql。有什么想法吗?

const http = require('http');
var mysql = require('mysql');

var con = mysql.createConnection({
   host     : 'localhost',
   user     : 'admin',
   password : 'password',
   database : 'members',
   port:3306
});
// Create an instance of the http server to handle HTTP requests
let app = http.createServer((req, res) => {
    // Set a response type of plain text for the response
    res.writeHead(200, {'Content-Type': 'text/plain'});

    // Send back a response and end the connection
    res.end('Hello World!\n');   
    con.connect(function(err) {
    if (err) throw err;
    res.end('Connected!');
    }); 

});

// Start the server on port 3000
app.listen(3000, '127.0.0.1');
console.log('Node server running on port 3000');
回答如下:您已经创建了服务器,并且正在根据HTTP API请求建立连接,这就是您无法在命令行上看到任何内容的原因。尝试在邮递员上点击localhost:3000,您将能够看到连接。您还需要进行另一项更正,以避免在连接到数据库之前发送响应。

const http = require('http'); var mysql = require('mysql'); var con = mysql.createConnection({ host : 'localhost', user : 'admin', password : 'password', database : 'members', port:3306 }); // Create an instance of the http server to handle HTTP requests let app = http.createServer((req, res) => { // Set a response type of plain text for the response res.writeHead(200, {'Content-Type': 'text/plain'}); // Send back a response and end the connection //res.end('Hello World!\n'); // comment this line con.connect(function(err) { if (err) throw err; res.end('Connected!'); }); }); // Start the server on port 3000 app.listen(3000, '127.0.0.1'); console.log('Node server running on port 3000');
