使用s3服务器端加密PHP - Using s3 server-side encryption with PHP

我已经决定利用amazon新的服务器端加密与s3，但是，我遇到了一个问题，我无法解决。

我使用s3 PHP类在这里找到:https://github.com/tpyo/amazon-s3-php-class

我原来一直使用这段代码来放置对象(它是工作的):

     S3::putObjectFile($file, $s3_bucket_name, $file_path, S3::ACL_PRIVATE,
         array(),
    array( 
        "Content-Disposition" => "attachment; filename=$filename",
        "Content-Type" => "application/octet-stream"
            )
);

然后我按照这里的指示做了:http://docs.amazonwebservices.com/AmazonS3/latest/API/index.html?RESTObjectPUT.html并添加了'x-amz-server -encryption'请求头。但是现在，当我尝试放置一个对象时，它会失败，没有错误。

我的新代码是:

  S3::putObjectFile($file, $s3_bucket_name, $file_path, S3::ACL_PRIVATE,
     array(),
array( 
    "Content-Disposition" => "attachment; filename=$filename",
    "Content-Type" => "application/octet-stream",
        "x-amz-server-side-encryption" => "AES256"
        )

);

有人尝试过这个新功能吗?或者有人看到代码中的错误吗?

欢呼。

标题应该是$metaHeaders数组的一部分，而不是$requestHeaders数组的一部分。

S3::putObjectFile($file, $s3_bucket_name, $file_path, S3::ACL_PRIVATE,
     array(
        "x-amz-server-side-encryption" => "AES256"
     ),
     array( 
       "Content-Disposition" => "attachment; filename=$filename",
       "Content-Type" => "application/octet-stream"
     )
);

下面是来自文档的方法定义:

putObject (mixed $input, 
           string $bucket, 
           string $uri, 
           [constant $acl = S3::ACL_PRIVATE], 
           [array $metaHeaders = array()], 
           [array $requestHeaders = array()])

你也可以考虑使用SDK的PHP?

我们可以使用下面的代码上传加密文件$s3->create_object($bucket_name,$destination,array( 'acl'=>AmazonS3::ACL_PUBLIC, 'fileUpload' => $file_local, 'encryption'=>"AES256"));

你可以从这里下载最新的sdk

使用官方SDK:

use Aws'S3'S3Client;
$bucket = '*** Your Bucket Name ***';
$keyname = '*** Your Object Key ***';
// $filepath should be absolute path to a file on disk                      
$filepath = '*** Your File Path ***';
// Instantiate the client.
$s3 = S3Client::factory();
// Upload a file with server-side encryption.
$result = $s3->putObject(array(
    'Bucket'               => $bucket,
    'Key'                  => $keyname,
    'SourceFile'           => $filepath,
    'ServerSideEncryption' => 'AES256',
));

更改现有对象的服务器端加密(复制操作)

use Aws'S3'S3Client;
$sourceBucket = '*** Your Source Bucket Name ***';
$sourceKeyname = '*** Your Source Object Key ***';
$targetBucket = '*** Your Target Bucket Name ***';
$targetKeyname = '*** Your Target Object Key ***';
// Instantiate the client.
$s3 = S3Client::factory();
// Copy an object and add server-side encryption.
$result = $s3->copyObject(array(
    'Bucket'               => $targetBucket,
    'Key'                  => $targetKeyname,
    'CopySource'           => "{$sourceBucket}/{$sourceKeyname}",
    'ServerSideEncryption' => 'AES256',
));

使用laravel 5+可以通过filesystems.php配置轻松完成，您不需要获取驱动程序或低级对象。

's3' => [
  'driver' => 's3',
  'key'    => "Your Key",
  'secret' => "Your Secret",
  'region' => "Bucket Region",
  'bucket' => "Bucket Name",
  'options' => [
    'ServerSideEncryption' => 'AES256',
  ]
],
//Code
$disk->put("filename", "content", "public"); // will have AES for file
