Performing a Streaming Download

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see API Reference.

Sample code:

<?php

// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with the source code.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
use Obs\ObsException;
// Create an ObsClient instance.
$obsClient = new ObsClient([ 
    // Obtain an AK/SK pair using environment variables (recommended) or import an AK/SK pair in other ways. Using hard coding may result in leakage.
    //Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
    'key' => getenv('ACCESS_KEY_ID'),
    'secret' => getenv('SECRET_ACCESS_KEY'),
    'endpoint' => 'https://your-endpoint',
    'signature' => 'obs'
]);

try {
    $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);
    }
} catch (ObsException $e) {
    // If the operation fails, obtain the exception details.
    printf("GetObjectFailed: Status:%d, Code:%s, Message:%s\n", $e->getStatusCode(), $e->getExceptionCode(), $e->getExceptionMessage());
} finally {
    $obsClient->close();
}

• 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.
