Gestion des erreurs

S3 Transfer Manager utilise des promesses pour les opérations asynchrones. Vous pouvez gérer les erreurs à l'aide de la then méthode otherwise ou de la promesse. Vous pouvez également encapsuler votre implémentation dans un try-catch bloc.

Gestion des erreurs de promesse

En utilisant otherwise :

<?php

use Aws\S3\S3Transfer\Models\UploadRequest;
use Aws\S3\S3Transfer\S3TransferManager;

require __DIR__ . '/../vendor/autoload.php';

$transferManager = new S3TransferManager(null, []);
$uploadPromise = $transferManager->upload(
    new UploadRequest(
        '/path/to/file.txt',
        [
            'Bucket' => 'amzn-s3-demo-bucket',
            'Key'    => 'file.txt',
        ]
    )
);

$uploadPromise->otherwise(function (Throwable $reason) {
    echo "Upload failed: " . $reason->getMessage() . "\n";
});

En utilisant then :

<?php

use Aws\S3\S3Transfer\Models\UploadRequest;
use Aws\S3\S3Transfer\Models\UploadResult;
use Aws\S3\S3Transfer\S3TransferManager;

require __DIR__ . '/../vendor/autoload.php';

$transferManager = new S3TransferManager(null, []);
$uploadPromise = $transferManager->upload(
    new UploadRequest(
        '/path/to/file.txt',
        [
            'Bucket' => 'amzn-s3-demo-bucket',
            'Key'    => 'file.txt',
        ]
    )
);


$uploadPromise->then(
    function (UploadResult $result) {
        echo "Upload succeeded!\n";
    },
    function (Throwable $error) {
        echo "Upload failed: " . $error->getMessage() . "\n";
    }
)->wait();

Utilisation du bloc try-catch

<?php

use Aws\S3\S3Transfer\Exception\S3TransferException;
use Aws\S3\S3Transfer\Models\UploadRequest;
use Aws\S3\S3Transfer\S3TransferManager;

require __DIR__ . '/../vendor/autoload.php';

$transferManager = new S3TransferManager(null, []);

$uploadPromise = $transferManager->upload(
    new UploadRequest(
        '/path/to/file.txt',
        [
            'Bucket' => 'amzn-s3-demo-bucket',
            'Key'    => 'file.txt',
        ]
    )
);

try {
    $uploadPromise->wait();
} catch (S3TransferException $exception) {
    echo "Upload failed: " . $exception->getMessage() . "\n";
}

Politiques relatives aux défaillances des opérations d'annuaire

Pour les opérations d'annuaire, vous pouvez également spécifier un rappel de politique d'échec. Ce rappel gère les échecs de fichiers individuels et décide si le téléchargement du répertoire doit se poursuivre.

<?php

use Aws\S3\S3Transfer\Models\UploadDirectoryRequest;
use Aws\S3\S3Transfer\S3TransferManager;

require __DIR__ . '/../vendor/autoload.php';

$transferManager = new S3TransferManager(null, []);

$uploadDirPromise = $transferManager->uploadDirectory(
    new UploadDirectoryRequest(
        '/path/to/directory',
        'amzn-s3-demo-bucket',
        [],
        [
            'failure_policy' => function (
                $requestArgs,
                $uploadDirectoryRequestArgs,
                $reason,
                $uploadDirectoryResponse
            ) {
                echo "Failed to upload {$requestArgs['Key']}: " .
                    "{$reason->getMessage()}\n";
                echo "So far, uploaded: " .
                    "{$uploadDirectoryResponse->getObjectsUploaded()}, " .
                    "failed: {$uploadDirectoryResponse->getObjectsFailed()}\n";

                // Return true to continue with other files, 
                // or throw an exception to abort.
                return true;
            },
        ]
    )
);
$uploadDirPromise->wait();

<?php

use Aws\S3\S3Transfer\Models\DownloadDirectoryRequest;
use Aws\S3\S3Transfer\S3TransferManager;

require __DIR__ . '/../vendor/autoload.php';

$transferManager = new S3TransferManager(null, []);

// Log errors but continue with other files.
$downloadDirPromise = $transferManager->downloadDirectory(
    new DownloadDirectoryRequest(
        'amzn-s3-demo-bucket',
        '/path/to/directory',
        [],
        [
            'failure_policy' => function (
                $requestArgs,
                $downloadDirectoryRequestArgs,
                $reason,
                $downloadDirectoryResponse
            ) {
                error_log("Failed to download {$requestArgs['Key']}: " .
                    "{$reason->getMessage()}");

                // If we've had too many failures, abort the entire operation.
                if ($downloadDirectoryResponse->getObjectsFailed() > 10) {
                    throw new \Exception(
                        "Too many download failures, aborting operation"
                    );
                }

                // Return void to continue with other files.
                return;
            },
        ]
    )
);
$downloadDirPromise->wait();
