Performing a Streaming Upload

Streaming upload uses resource or GuzzleHttp\Psr7\StreamInterface as the data source of an object. Sample code is as follows:

Uploading a Network Stream

// 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'
] );

$resp = $obsClient->putObject([
       'Bucket' => 'bucketname',
       'Key' => 'objectname',
       // Create network streams.
       'Body' => fopen('http://www.a.com','r')
]);

printf("RequestId:%s\n",$resp['RequestId']);

Uploading a File Stream

// 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'
] );

$resp = $obsClient->putObject([
       'Bucket' => 'bucketname',
       'Key' => 'objectname',
       'Body' => fopen('localfile', 'r')
]);

printf("RequestId:%s\n",$resp['RequestId']);
  • If the Body parameter is used to specify the to-be-uploaded streaming data, its value must be a resource or GuzzleHttp\Psr7\StreamInterface object.
  • To upload a large file, you are advised to use multipart upload.
