javascript - 无法通过 sequelize.authenticate() 方法使用异步等待

Question

SQL 密码每 24 小时过期一次(间隔可能随时更改，恕不另行通知)，因此我想在运行 SQL 查询之前使用 Sequelize beforeConnect Hook 验证身份验证。
如果没有 async await，SQL 查询将失败，然后进行身份验证，前面的查询将通过。我想以异步方式运行代码，因此没有 SQL 查询失败。请帮我解决这个问题。

    const sequelize = new Sequelize(database, username, password, params);

    sequelize.beforeConnect(async (currConfig) => {
        try {
            await sequelize.authenticate();
            console.log('Connection has been established successfully.');
        } catch (error) {
            console.error('Unable to connect to the database:', error);
        }
    });

您可以 promise beforeConnect

let currConfig = await prepare(sequelize);
try {
  await sequelize.authenticate();
  console.log("Connection has been established successfully.");
} catch (error) {
  console.error("Unable to connect to the database:", error);
}

function prepare(sequelize) {
  return new Promise(res => {
    sequelize.beforeConnect(config => res(config));
  });
}

只要确保你的函数有 async在它面前
