使用 php 从 AWS S3 获取私有文件

Question

我正在尝试从 AWS S3 获取私有文件但出现错误

 $client = S3Client::factory([
        'version' => 'latest',
        'region'  => 'us-west-2',
        'signature'    => 'v4',
        'credentials' => [
            'key'    => '****',
            'secret' => '-****'
        ]
    ]);


  $bucket =  'name';
    $file = 'lks/002geH1P1WFXGHWafCwgTw5mwm58X.pdf';
    $url = "{$bucket}/{$file}";

    $request = $client->get($url);
    $signedUrl = $client->createPresignedUrl($request, '+10 minutes');
    echo  $signedUrl;

我收到这个错误

可捕获的致命错误：参数 2 传递给 Aws\AwsClient::getCommand() 必须是数组类型，给定字符串， 在 /home/ubuntu/vendor/aws/aws-sdk-php/src/AwsClientTrait.php 中调用 在第 78 行并定义在 /home/ubuntu/vendor/aws/aws-sdk-php/src/AwsClient.php 在第 202 行

这行得通......希望它会帮助别人;）

$cmd = $client->getCommand('GetObject', [
            'Bucket' => $bucket,
            'Key' => $file
        ]);

        $request = $client->createPresignedRequest($cmd, '+20 minutes');
        $presignedUrl = (string)$request->getUri();
        echo $presignedUrl;
