Call to undefined method createPresignedUrl() using AWS SDK for PHP - php

Question

I could not create Presigned Url using AWS SDK for PHP. My code is -
function connect()
{
// Instantiate the S3 class and point it at the desired host
date_default_timezone_set('GMT');
return S3Client::factory(array(
'region' => 'us-west-2',
'version' => 'latest',
'credentials' => [
'key' => $key,
'secret' => $secret
]
));
function getSignedS3URLForObject($fileName)
{
// GET CURRENT DATE
$milliseconds = round(microtime(true) * 1000);
$expiration = $milliseconds + (1000 * 60 * 60 * 24 * 30 * 2);
$s3 = self::connect();
$command = $s3->getCommand('GetObject', array(
'Bucket' => self::$customerBucket,
'Key' => $fileName,
'ContentType' => 'image/jpeg',
'Body' => '',
'ContentMD5' => false
));
$signedUrl = $command->createPresignedUrl($expiration);
echo urldecode($signedUrl);
return $signedUrl;
}
It gives me next error-
Fatal error: Call to undefined method
Aws\Command::createPresignedUrl() in

Answer 1

To force download any file on browser, you can use :
$command = $s3->getCommand('GetObject', array(
'Bucket' => 'bucketname',
'Key' => 'filename',
'ResponseContentType' => 'application/octet-stream',
'ResponseContentDisposition' => 'attachment'
));
// Create a signed URL from the command object that will last for
// 2 minutes from the current time
$response = $s3->createPresignedRequest($command, '+2 minutes');
$presignedUrl = (string)$response->getUri();

Answer 2

Using s3.0.0 v3 - I did the following to get this to work.
$command = $s3->getCommand('GetObject', array(
'Bucket' => $this->customerBucket,
'Key' => $fileName,
'ContentType' => 'image/png',
'ResponseContentDisposition' => 'attachment; filename="'.$fileName.'"'
));
$signedUrl = $s3->createPresignedRequest($command, "+1 week");
