Question

有没有办法一次上传多个文件，而不必为每个文件重新连接？

我使用S3作为我的php应用程序的存储空间，它需要存储大多数（大约10k）图像文件的大数字（一次100个）。目前我正在循环浏览它们并使用以下代码单独上传：

$s3->putObjectFile($uploadFile, $bucketName, ($uploadFile), S3::ACL_PUBLIC_READ)

这需要很长时间。 1.5兆的文件大概一分钟。如其他答案中所建议的那样关闭SSL会减少到大约40秒，但这仍然很慢。

这是我当前的代码，使用PHP的Amazon S3 REST实现

$s3 = new S3($awsAccessKey, $awsSecretKey, false);


function send_to_s3($s3, $bucketName, $uploadFile)

{

    $start = microtime(true);



// Check if our upload file exists
if (!file_exists($uploadFile) || !is_file($uploadFile))
    exit("\nERROR: No such file: $uploadFile\n\n");

// Check for CURL
if (!extension_loaded('curl') && !@dl(PHP_SHLIB_SUFFIX == 'so' ? 'curl.so' : 'php_curl.dll'))
    exit("\nERROR: CURL extension not loaded\n\n");



if ($s3->putObjectFile($uploadFile, $bucketName, ($uploadFile), S3::ACL_PUBLIC_READ)) 
    {

    $end = microtime(true);

    $took = $end - $start;

    echo "S3::putObjectFile(): File copied to {$bucketName}/".($uploadFile).PHP_EOL . ' - ' . filesize($uploadFile) . ' in ' . $took . ' seconds<br />';

    return $took;
    }
else
    {
    print 'error';  
    }

}

感谢任何帮助。

use Aws\S3\S3Client;    
use Aws\CommandPool;    
use Guzzle\Service\Exception\CommandTransferException;    

$commands = array();    
foreach ( $objects as $key => $file ) { 
    $fileContent = $file['body'];
        $objParams = array (    
            'ACL' => 'bucket-owner-full-control',    
            'Bucket' => 'bucket_name',    
            'Key' => 's3_path',    
            'Body' => $fileContent     
        );    
        $commands[] = $clientS3->getCommand('PutObject', $objParams);    
    }    
    try {    
        $results = CommandPool::batch($clientS3, $commands);    
    } catch (CommandTransferException $e) {    
        $succeeded = $e->getSuccessfulCommands();    
        echo "Failed Commands:\n";    
        foreach ($e->getFailedCommands() as $failedCommand) {    
            echo $e->getExceptionForFailedCommand($failedCommand)->getMessage() . "\n";    
        }    
    }

我建议通过分段上传来上传图片。

以下代码是使用Aws-sdk版本3的基本示例。

use Aws\S3\MultipartUploader;
use Aws\Exception\MultipartUploadException;

$uploader = new MultipartUploader($s3Client, '/path/to/large/file.zip', [
    'bucket' => 'your-bucket',
    'key'    => 'my-file.zip',
]);

try {
    $uploader->upload();
    echo "Upload complete.\n";
} catch (MultipartUploadException $e) {
    echo $e->getMessage() . "\n";
}

从PHP上传多个文件到Amazon S3
