亚马逊api上传不工作

Question

我正在使用amazon api上传我的内容 这是我的代码

 set_time_limit(0);
 require 'aws-autoloader.php';
 use Aws\S3\S3Client;
 // Instantiate the S3 client with your AWS credentials
$s3 = S3Client::factory(array(
 'key'    => '**** Key ******',
 'secret' => '**** Secret Key *******'
));



 $commands = array();
 $commands[] = $s3->getCommand('PutObject', array(
  'Bucket' => 'application-data',
  'Key'    => 'test.txt',
  'Body'   => fopen('test.txt', 'r'),
 ));

$s3->execute($commands);

 foreach ($commands as $command) {
  $result = $command->getResult();
  echo "<pre>";
  print_r($result);

}

但我收到了这个错误
