如何在php中生成s3存储桶后上传mpdf文件

Question

生成后我可以将pdf文件上传到s3服务器吗？

$file_name = $pdf->Output(time().'_'.'E-Prescription.pdf','F');

Answer 1

要做到这一点，你可以使用AWS SDK for PHP。

首先，您需要使用配置文件凭据创建客户端。

use Aws\S3\S3Client;

$client = S3Client::factory(array(
        'credentials' => array(
            'key'    => 'YOUR_AWS_ACCESS_KEY_ID',
            'secret' => 'YOUR_AWS_SECRET_ACCESS_KEY',
        )
    ));

并且，如果存储桶已存在，您可以从文件系统上传文件，如下所示：

$result = $client->putObject(array(
    'Bucket'     => $bucket,
    'Key'        => $file_name,
    'SourceFile' => $pathToFile
));

Answer 2

假设您使用composer在项目中安装了AWS SDK;特别...

composer require aws/aws-sdk-php

是的，你可以使用这样的流包装器：

require "vendor/autoload.php";

$aws_file = 's3://bucketname/foldername/your_file_name.pdf';

//the folder is optional if you have one within your bucket

try {

    $s3->registerStreamWrapper();
    $mpdf->Output($aws_file, \Mpdf\Output\Destination::FILE);
}
catch (S3Exception $e) {

    $data['error'] = $e->getMessage();
    //show the error as a JSON callback that you can use for troubleshooting
    echo json_encode($data);
    exit();
}

您可能必须按如下方式向Web服务器添加写入权限（在Ubuntu AWS EC2上使用Apache服务器）：

sudo chown -R www-data /var/www/html/vendor/mpdf/mpdf/src/Config/tmp
sudo chmod -R 755 /var/www/html/vendor/mpdf/mpdf/src/Config/tmp

然后编辑在以下位置找到的ConfigVariables.php文件：

\vendor\mpdf\mpdf\src\Config

更改：

'tempDir' => __DIR__ . '/../../tmp',

至：

'tempDir' => __DIR__ . '/tmp',

然后在同一目录中创建一个名为“tmp”的空文件夹。然后高兴地上传。
