我无法将 Node.js 项目与 Mamp 数据库连接起来

Question

您好，我正在使用以下代码连接 Mamp 数据库“http://localhost:8888/phpMyAdmin/server_databases.php?server=1”，但无法做到以下几点错误

代码：-

const db = mysql.createConnection({
    host: 'localhost',
    user: 'root',
    password: 'root',
    database: 'nodejs.login',
})

db.connect((error) =>{
    if(error){
        console.log(error)
    }else {
        console.log("Mysql Connected....")
    }
    
})

错误：-

server startwd on Port 5003
{ Error: connect ECONNREFUSED 127.0.0.1:3306
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1117:14)

Answer 1

您的问题可能出在连接参数上，您正在设置 password: 'root'。根据我的经验，密码通常留空：password: ''.

Answer 2

我能够解决 it.i 检查并发现我的 Mamp 服务器是运行在 8889 所以我在连接 port: '8889' 中又添加了一个变量。
