如何在php中生成s3 bucket后上传mpdf文件

生成后是否可以将mpdf文件上载到s3服务器

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

---

要做到这一点，您可以使用

首先，您需要使用配置文件凭据创建一个客户端

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bucket已经存在，您可以像这样从文件系统上传您的文件：

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

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();
}

---

假设您使用composer在项目中安装了AWS SDK；具体地说

composer require aws/aws-sdk-php

是的，您可以这样使用流包装器：

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

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（使用Ubuntu AWS EC2上的Apache服务器）：

然后编辑位于以下位置的ConfigVariables.php文件：

\vendor\mpdf\mpdf\src\Config

更改：

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

致：

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。

            'secret' => AWS_S3_SECRET,
        ]
    ]);

    $s3->registerStreamWrapper();
    $mpdf->Output($aws_file); //Send yout mPDF File in s3-file-bucket
} catch (S3Exception $e) {
    die($e->getError().' => '.$e->getMessage();
