如何在 PHP 中使用 AWS SDK 读取 cloudTrail 日志

Question

我是 AWS 开发工具包 API 的新手。

我有一个 s3 存储桶（my-bucket）用于我的客户从那里下载文件。 每当我的客户从“my-bucket”下载文件时，我有一个 Trail(my-trail) 用于将日志传送到另一个 s3 存储桶(my-bucket-logs)。

我想从“my-bucket-logs”中读取日志并将它们保存在我的 CMS 中以生成各种报告。是否可以获取日志？我试过下面的PHP代码。我不确定这段代码是否正确。

require 'vendor/autoload.php';
$config = [
    'version' => 'latest',
    'region'  => 'us-east-1',
    'key' => MY_AWS_KEY,
    'secret'  => MY_AWS_SECRETE
];
$s3client = new Aws\S3\S3Client($config);
$trailClient = new Aws\CloudTrail\CloudTrailClient($config);


$result = $trailClient->lookupEvents([
    'EndTime' => time(),
    'LookupAttributes' => [
        [
            'AttributeKey' => 'eventName',// 'get', // REQUIRED
            'AttributeValue' => 'ListObjects' //get', // REQUIRED
        ],
        // ...
    ],
    'MaxResults' => 1000
    //'NextToken' => '<string>',
    //'StartTime' => '01/12/2017',
]);

print_r($result);

收到此错误：

PHP Fatal error:  Uncaught exception 'Aws\CloudTrail\Exception\CloudTrailException' with message 'Error executing "LookupEvents" on "https://cloudtrail.us-east-1.amazonaws.com"; AWS HTTP error: Client error: `POST https://cloudtrail.us-east-1.amazonaws.com` resulted in a `400 Bad Request` response:

是否可以在 PHP 中使用 AWS 开发工具包 API 获取日志？

我可以从 s3 存储桶中读取日志。这只是从 s3 存储桶本身下载文件的问题，而我使用 Aws\CloudTrail\CloudTrailClient 搞砸了。
