如何解決連接問題 Sequelize

Question

我是 sequelize orm 的新手，我正在使用 mysql 數據庫並嘗試連接我的數據庫，但我沒有任何連接或任何錯誤有人可以解決我的代碼出了什么問題這是 sequelize 文檔鏈接https：/ /sequelize.org/docs/v6/getting-started/

import {Sequelize} from 'sequelize';


const dbConfig={
        "dbName":"mydb",
        "dbUser":"root",
        "bdHost":"localhost",
        "dbPassword":"Dell@8054",
        "dbPort":"3306",
        "dialect":"mysql"
        };


const sequelize = new Sequelize(dbConfig.db, dbConfig.dbUser, dbConfig.dbPassword, {
    host: dbConfig.bdHost,
    dialect: dbConfig.dialect,
    port:3306
  });
 
 sequelize
  .authenticate().then(con=>{console.log("con",con)}).catch(err=>{console.log("err",err)})

控制台的 Output 是 -- con undefined

您可以使用

sequelize
.authenticate()
.then(() => {
   logger.info('MySQL connection has been established successfully.')  
})  
.catch(err => {
   logger.error('Unable to connect to the database:', err);
   process.exit(2)  
})
