php – 将base64图像上传到amazon s3

<?php
require_once 'classes/amazon.php';
require_once 'includes/aws/aws-autoloader.php';
use AwsS3S3Client;

$putdata = file_get_contents("php://input");
$request = json_decode($putdata);

$image_parts = explode(";base64,",$request->image);
$image_type_aux = explode("image/",$image_parts[0]);
$image_type = $image_type_aux[1];
$image_base64 = $image_parts[1];

$dateTime = new DateTime();
$fileName = $dateTime->getTimestamp() . "." . $image_type;  

$s3Client = S3Client::factory(array(
    'region' => 'eu-west-1','version' => '2006-03-01','credentials' => array(
        'key'    => Amazon::getAccessKey(),'secret' => Amazon::getSecretKey(),)
));

try {
    $result = $s3Client->putObject(array(
        'Bucket'          => Amazon::getBucket(),'Key'             => 'banners/' . $fileName,'Body'            => $image_base64,'ContentType'     => 'image/' . $image_type,'ACL'             => 'public-read'
    ));
    echo $result['ObjectURL'] . "n";
} catch(S3Exception $e) {
    echo $e->getMessage() . "n";
}
?>

因此,当我在上传图像文件后检查控制台时,它具有预期的大小,权限和标题,但正如我所说,每当我尝试打开文件时,它都会失败.

这可能是什么问题？提前致谢.
