Performing a Streaming Download

Sample code:

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during source code installation.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
// Create an instance of ObsClient.
$obsClient = new ObsClient ( [ 
      //Obtain an AK/SK pair using environment variables or import the AK/SK pair in other ways. Using hard coding may result in leakage.
      //Obtain an AK/SK pair on the management console.
      'key' => getenv('ACCESS_KEY_ID'),
      'secret' => getenv('SECRET_ACCESS_KEY'),
      'endpoint' => 'https://your-endpoint',
      'signature' => 'obs'
] );

$resp = $obsClient -> getObject([
       'Bucket' => 'bucketname',
       'Key' => 'objectname',
       'SaveAsStream' => true
]);

printf("RequestId:%s\n", $resp['RequestId']);
printf("Object Content:\n");
while(!$resp['Body'] -> eof()){
       echo $resp['Body'] -> read(65536);
}

• Use the SaveAsStream parameter to specify the download mode to streaming download.
• Body in the returned result is a readable GuzzleHttp\Psr7\StreamInterface object and can be used to save the object to a local directory or to the memory.
