从 AWS lambda（Alexa 技能的后端）连接到外部 Mysql 数据库 returns "Access denied for user" 消息

Question

我正在 Javascript 中编写一个 Alexa lambda 函数来连接到我的外部数据库。我已经使用相同的用户名和密码成功访问了该数据库。我已经从笔记本电脑的 noded_modules 文件夹上传了 mysql 代码。这是 Javascript 代码：

        var mysql = require('mysql');

        var con = mysql.createConnection({
          host: "www.oryxtech.net",
          user: "",
          password: "" 
        });

        con.connect(function(err) {
          if (err) throw err;
          console.log("Connected!");
        });

这是来自 lambda 控制台的错误消息：

是我做错了什么，还是我漏掉了一步？在此先感谢您的帮助。

用户 oryxtech_sideE 似乎未被授予从主机 ec2-3-85-146-115.compute-1.amazonaws.com 访问数据库的权限。请确认相同。

您可以授权用户访问主机

GRANT ALL ON *.* to 'oryxtech_sideE'@'ec2-3-85-146-115.compute-1.amazonaws.com' IDENTIFIED BY 'password';

或任何主机：

GRANT ALL ON *.* to 'oryxtech_sideE'@'%' IDENTIFIED BY 'password';

参考： Allow all remote connections, MySQL

希望对您有所帮助。
