Question

我刚开始尝试使用Amazon S3来托管我的网站图片。我正在使用官方的Amazon AWS PHP SDK库。

问题：如何删除位于S3'文件夹中的所有文件？例如，如果我有一个名为images/2012/photo.jpg的文件，我想删除文件名以images/2012/开头的所有文件。

Answer 1

从S3删除文件夹及其所有文件的最佳方法是使用API deleteMatchingObjects()

$s3 = S3Client::factory(...);
$s3->deleteMatchingObjects('YOUR_BUCKET_NAME', '/some/dir');

Answer 2

S3没有像传统上在文件系统中想到的那样“文件夹”（有些S3客户端做得很好，使得出现有文件夹）。那些/实际上是文件名的一部分。

因此，API中没有“删除文件夹”选项。您只需要删除具有images/2012/...前缀的每个文件。

<强>更新

这可以通过Amazon S3 PHP客户端中的delete_all_objects方法完成。只需在第二个参数中指定"/^images\/2012\//"作为正则表达式前缀（第一个参数是您的存储桶名称）。

Answer 3

这是一个可以完成您要做的事情的功能。

/**
*   This function will delete a directory.  It first needs to look up all objects with the specified directory
*   and then delete the objects.
*/
function Amazon_s3_delete_dir($dir){
    $s3 = new AmazonS3();

    //the $dir is the path to the directory including the directory

    // the directories need to have a / at the end.  
    // Clear it just in case it may or may not be there and then add it back in.
            $dir = rtrim($dir, "/");
            $dir = ltrim($dir, "/");
            $dir = $dir . "/";

    //get list of directories
        $response = $s3->get_object_list(YOUR_A3_BUCKET, array(
           'prefix' => $dir
        ));


    //delete each 
        foreach ($response as $v) {
            $s3->delete_object(YOUR_A3_BUCKET, $v);
        }//foreach

    return true;

}//function

使用：如果我想删除目录foo

Amazon_s3_delete_dir("path/to/directory/foo/");

我已经对此进行了测试，并于2019-05-28生效

function Amazon_s3_delete_dir($delPath, $s3, $bucket) {
//the $dir is the path to the directory including the directory
// the directories need to have a / at the end.  
// Clear it just in case it may or may not be there and then add it back in.
$dir = rtrim($dir, "/");
$dir = ltrim($dir, "/");
$dir = $dir . "/";

$response = $s3->getIterator(
        'ListObjects',
        [
            'Bucket' => $bucket,
            'Prefix' => $delPath
        ]
);
//delete each 
foreach ($response as $object) {
    $fileName = $object['Key'];
    $s3->deleteObject([
        'Bucket' => $bucket,
        'Key' => $fileName
    ]);
}//foreach

    return true;
 }//function

用法：

$delPath = $myDir . $theFolderName . "/";        
Amazon_s3_delete_dir($delPath, $s3, $bucket);

Answer 5

$s3 = new Aws\S3\Client([ 'region' => 'us-west-2', 'version' => 'latest' ]); 
$listObjectsParams = ['Bucket' => 'foo', 'Prefix' => 'starts/with/']; 

// Asynchronously delete 
$delete = Aws\S3\BatchDelete::fromListObjects($s3, $listObjectsParams); 

// Force synchronous completion $delete->delete();
$promise = $delete->promise();
