使用新的PHP SDK更新AWS S3项目ACL

如何使用新的AWS S3 PHP SDK使用“公共读取”更新S3中的项目：似乎只有获取和放置才可能

迭代器返回一个数组，而不是一个类。Get对象返回一个类，但没有明显的更新方法。CopyObject看起来有点像黑客

$s3->copyObject(array(
        'Bucket'     => 'media',
        'Key'        => $k,
        'CopySource' => 'media'.'/'.$k,
        'ACL'        => 'public-read',
));

返回：

PHP Fatal error:  Uncaught Aws\S3\Exception\InvalidRequestException: AWS Error Code: InvalidRequest, Status Code: 400, AWS Request ID: FC630F89A049823A, AWS Error Type: client, AWS Error Message: This copy request is illegal because it is trying to copy an object to itself without changing the object's metadata, storage class, website redirect location or encryption attributes., User-Agent: aws-sdk-php2/2.5.3 Guzzle/3.8.1 curl/7.35.0 PHP/5.5.9-1ubuntu4.4 thrown in /.../vendor/aws/aws-sdk-php/src/Aws/Common/Exception/NamespaceExceptionFactory.php on line 91

迟做总比不做好

$s3Client->putObjectAcl(array(
    'Bucket'     => 'yourbucket',
    'Key'        => 'yourkey',
    'ACL'    => 'public-read'
));
