解决承诺的Claudia API问题

Question

我正在lambda上测试claudia api，我只想打开与mysql服务器的连接并返回连接是否成功。我有一个hello world，可以在其中简单地通过api返回字符串。每当我尝试创建一个Promise，然后在该Promise中打开一个连接，然后用结果解析Promise时，Promise就永远不会解析，并且Lambda函数会超时。我知道这意味着我永远不会解决所创建的承诺，但是我不确定在连接代码完成后如何正确解决它。在连接aysnc代码完成之后，如何等待解决承诺？

    const ApiBuilder = require('claudia-api-builder')
var api = new ApiBuilder()

const mysql = require('mysql');


var connection = mysql.createConnection({
    host: 'myserverurl',
    port: '3306',
    user: 'username',
    password : 'password',
    database: 'db'

});


var sql = "SELECT * FROM UserStatus"


api.get('/test', function (request) { // GET all users
    var results = ""
   return new Promise (function (resolve,reject) {
        connection.connect(function(err) {
            if (err) {
                results = "fail"

            }
            results = "connected"
            resolve(results)

        })
        resolve("I know that I need to resolve the promise here, but not sure how to make this wait for connection to finish")
   });
});
module.exports = api;
