nodejs Sequelize6连接mysql8的配置怎么写

官方文档的构造器很多，这里仅展示一种 const { Sequelize } = require('sequelize'); /**  * dbname  * username  * password  * options  */ const sequelize = new Sequelize('dbname', 'username', 'password', {     host: '127.0.0.1',  //注意一定不要写成localhost，不然会连不上数据库，报最后附上的错误     dialect: 'mysql',     port: 3306, 　//以下配置在dialectOptions中的参数会被加在连接地址后作为参数传给mysql等同于 　//mysql://localhost:3306/dbname?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=Asia/Shanghai 　//自己看着加参数，不加也行，也能连上mysql     // dialectOptions: {       //     useSSL: false,     //     allowPublicKeyRetrieval: true,     //     serverTimezone: 'Asia/Shanghai',     //     useUnicode: true,     //     characterEncoding: 'UTF-8'     //   },   });   async function connect() {     try {         await sequelize.authenticate();         console.log('Connection has been established successfully.');     } catch (error) {         console.error('Unable to connect to the database:', error);     } }   connect()   ################################################## host写localhost会报的错，改成ipv4地址连接就行了
