我在将数据发送到我的 DynamoDB 时遇到问题。我不知道问题是什么,因为它似乎程序运行正确,但是我的数据库中似乎没有任何数据。我能够使用Amazons tutorial创建表,但是当我按照本教程进行操作时,如果我尝试放置所有项目,我会得到一个失败的响应,而当它只有一个项目时,我会得到一个错误的成功,因为数据库中没有任何更新。
这是代码,如果有人知道调试此类问题的方法,我特别好奇。
<?php
// If necessary, reference the sdk.class.php file.
// For example, the following line assumes the sdk.class.php file is
// in an sdk sub-directory relative to this file
require_once('includes/backend.php');
// Instantiate the class
$dynamodb = new AmazonDynamoDB();
