Question

我试图克服与S3有关的路障情况。

背景：从我的移动应用程序中，用户最多可以选择10张图像并将其发布到服务器。它被接收并移到AWS实例中的相关文件夹中-为了便于讨论，我们将其称为实例“ A”。当文件移动到实例“ A”时，我们称为“ moveFileToS3”。代码看起来像这样。

foreach($_FILES as $file)
                    {
                            $file_info = $file['name'];
                            $extension = pathinfo($file['name'],PATHINFO_EXTENSION);
                            $destination_file_name = $imagesMoved . '-'. $sku . '.'. $extension;
                            $file_path = $images_directory . $destination_file_name;

                            if (move_uploaded_file($file['tmp_name'], $file_path))
                            {
                                    $imagesMoved++;
                                   //Move the file to S3
                                    moveFileToS3($destination_file_name, $images_directory, $parent_folder . '/' . $images_folder . '/');

                            }

                            if (intval($imagesMoved) == intval($totalFileCount))
                            {
                                    $image_moved = true;
                                    //Begin to update the DB
                            }
                    }

未进行此调用（moveFileToS3）..用户选择的所有文件都使其成为实例“ A”。

但是，当进行此调用（moveFileToS3）时...并非用户选择的所有文件都将其转移到实例“ A”，并且只有实例“ A”中的一些文件移至S3位置。 $ image_moved = true之后的任何一条指令都不会执行。

为克服这种情况提供的任何帮助将不胜感激。我已附上包含方法“ moveFileToS3”的文件，供您快速参考。

<?php
require  '../api/vendor/autoload.php';

use Aws\Common\Exception\MultipartUploadException;
use Aws\S3\MultipartUploader;
use Aws\S3\S3Client;

function moveFileToS3($fileName, $fileLocation, $targetLocation)
{
    date_default_timezone_set('Asia/Kolkata');

    $region  = 'xxxxx';
    $version = 'xxxxx';
    $bucket = 'xx-xxxxxx-xxxxx';
    $endpoint = 'xxxxxxxx.s3-accelerate.amazonaws.com';
    $key = 'xxxxxx';
    $secret = 'xxxxxxxxx';

    $fileFullPathLocal = $fileLocation.$fileName;

    $s3 = new S3Client([
        'version' => $version,
        'region'  => $region,
        'debug'   => true,
        'credentials' => [
            'key'    => $key,
            'secret' => $secret,
        ]
    ]);

    // Prepare the upload parameters.
    $uploader = new MultipartUploader($s3, $fileFullPathLocal, [
        'bucket' => $bucket,
        'key'    => $targetLocation.$fileName
    ]);

    // Perform the upload.
    try
    {
        $responseLogFile = fopen("../log/S3UploadLog_".date("Y-m-d").".log", "a+");
        fwrite($responseLogFile, '['.date("Y-m-d H:i:s").']: Upload Started : '.$fileName. PHP_EOL. PHP_EOL);
        fclose($responseLogFile);

        $result = $uploader->upload();

        $responseLogFile = fopen("../log/S3UploadLog_".date("Y-m-d").".log", "a+");
        fwrite($responseLogFile, '['.date("Y-m-d H:i:s").']: Upload Finished : '.$fileName. PHP_EOL. PHP_EOL);
//             fwrite($responseLogFile, '['.date("Y-m-d H:i:s").']: Upload Result : '.$result. PHP_EOL. PHP_EOL);
        fwrite($responseLogFile, '['.date("Y-m-d H:i:s").']: Object Url : '.$result['ObjectURL']. PHP_EOL. PHP_EOL);
        fclose($responseLogFile);

//             echo "Upload complete: {$result['ObjectURL']}" . PHP_EOL;
        unlink($fileFullPathLocal);


    }
    catch (MultipartUploadException $e)
    {
        $responseLogFile = fopen("../log/S3UploadLog_".date("Y-m-d").".log", "a+");
        fwrite($responseLogFile, '['.date("Y-m-d H:i:s").']: Upload Failed : '.$fileName. PHP_EOL. PHP_EOL);
        fclose($responseLogFile);

        echo $e->getMessage() . PHP_EOL;
    }
}
?>

当您将文件从本地开发服务器移到存储桶时似乎会出现问题。但是当移至AWS环境时..没有任何问题

使用适用于PHP的AWS开发工具包
