低级API多部分文件上传过程不起作用

Question

我们正试图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 
    ) 

) 

上传/ tmp/phplA534j的第2部分。

Guzzle\Service\Resource\Model Object 
(

[structure:protected] => 
[data:protected] => Array 
    (
     [ServerSideEncryption] => 
     [ETag] => "d41d8uytrf67fdfrf00b204e9800998ecf8427e" 
     [SSECustomerAlgorithm] => 
     [SSECustomerKeyMD5] => 
     [RequestId] => YTYPO67167874586EF802536C 
    ) 

) 

上传/ tmp/phplA534j的第3部分。

你能帮我吗？

Answer 1

两件事。首先，你可以使用SourceFile代替Body：

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

第二，是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), 
));
