Unable to get AWS S3 exception

Question

I am trying to get the file size of an S3 object using the Stream API with the following code:

try{
    $fileSize = filesize("s3://".$bucket."/".$filename);
}catch(Aws\S3\Exception\NoSuchKeyException $e) {
    return false;
}

If the key does not exist, I get the following error:

[Tue Oct 13 23:03:32 2015] [error] [client 54.225.205.152] PHP Warning: file or directory not found: s3: //mybucket/myfile.jpg in / var / www / vendor / aws / aws - sdk-php / src / Aws / S3 / StreamWrapper.php on line 774

[Tue Oct 13 23:03:32 2015] [error] [client 54.225.205.152] PHP Warning: filesize (): stat failed for s3: //mybucket/myfile.jpg in / var / www / api - dev / awsFunc .php on line 278

[Tue Oct 13 23:03:32 2015] [error] [client 54.225.205.152] PHP Fatal error: inactive Aws \ S3 \ Exception \ NoSuchKeyException: AWS Error code: NoSuchKey, status code: 404, AWS request ID: 4A6F1372301D02F7, AWS Type of error: client, AWS Error message: The specified key does not exist., User-Agent: aws-sdk-php2 / 2.8.21 Guzzle / 3.9.3 curl / 7.22.0 PHP / 5.3.10-1ubuntu3.19 \ n is thrown in / var / www / vendor / aws / aws -sdk-php / src / Aws / Common / Exception / NamespaceExceptionFactory.php on line 91

So, although I am clearly trying to catch Aws \ S3 \ Exception \ NoSuchKeyException, the system still throws it.

UPDATE:

I found a mistake. The exception must contain a namespace starting with '\' instead of Aws, for example:

try{
    $fileSize = filesize("s3://".$bucket."/".$filename);
}catch(\Aws\S3\Exception\NoSuchKeyException $e) {
    return false;
}

, , use '\', , . , - .

, :

use Aws\S3\Exception\S3Exception as S3;


try {
    $podcast = $this->uploadFileToS3($request);
} catch(S3 $e) {
    return $e->getMessage();
 }

:

 return redirect('dashboard/episode/create')->with('status', $e->getMessage());

, , .

try {
    $fileSize = filesize("s3://".$bucket."/".$filename);
} catch(S3 $e) {
    return $e->getMessage();
 }

use Aws\Exception\AwsException;

try{
    // something

    echo 'Caught exception: ',  $e->getMessage(), "\n";
}

Answer 3

AWSException getAwsErrorMessage()

use Aws\S3\Exception\S3Exception;
 try {
     // Your Code       
 } catch (S3Exception $e) {
     return $e->getAwsErrorMessage();
 }
