php - 低级 API 分段文件上传过程不起作用

Question

我们正在尝试通过多部分文件上传过程上传文件。通过使用下面给出的代码:

while (!feof($file)) {

$result = $s3->uploadPart(array(
    'Bucket'     => $bucket,
    'Key'        => $key,
    'UploadId'   => $uploadId,
    'PartNumber' => $partNumber,
    'Body'       => fread($file, filesize($filename))
));
$parts[] = array(
    'PartNumber' => $partNumber++,
    'ETag'       => $result['ETag'],
);
}

//4.完成分段上传。

$result = $s3->completeMultipartUpload(array(

    'Bucket'   => $bucket,
    'Key'      => $key,
    'UploadId' => $uploadId,
    'Parts'    => $parts,
));
$url = $result['Location'];

fclose($file);

通过使用此代码，文件被转换为 Multipart 但无法上传文件。它通过 print_r 显示这种类型的错误:

Guzzle\Service\Resource\Model Object
(

[structure:protected] => 
[data:protected] => Array
    (
        [ServerSideEncryption] => 
        [ETag] => "fcfc6838dfrtefr87b27b642e7d63021"
        [SSECustomerAlgorithm] => 
        [SSECustomerKeyMD5] => 
        [RequestId] => 4RTYPEFE054567369BD46D
    )

)

你能帮帮我吗？

Answer 1

两件事。首先，您可以使用 SourceFile 而不是 Body:

$result = $s3->uploadPart(array(
    'Bucket'     => $bucket,
    'Key'        => $key,
    'UploadId'   => $uploadId,
    'PartNumber' => $partNumber,
    'SourceFile'       => 'Path/To/Your/File.ext')
));

其次，这不是完成上传的正确方法:

$result = $s3->completeMultipartUpload(array(

    'Bucket'   => $bucket,
    'Key'      => $key,
    'UploadId' => $uploadId,
    'MultipartUpload'    =>array('Parts'=>  $parts),
));
