如何解决连接问题 Sequelize

Question

我是 sequelize orm 的新手，我正在使用 mysql 数据库并尝试连接我的数据库，但我没有任何连接或任何错误有人可以解决我的代码出了什么问题这是 sequelize 文档链接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)  
})
