GetSessionToken命令沒有AWS SDK中發現

Question

我有以下代碼

<?php 

require '../aws/aws-autoloader.php'; 

use Aws\Sts\StsClient; 
use Aws\S3\S3Client; 

$sts = S3Client::factory(array(
    'key' => 'key', 
    'secret' => 'key', 
)); 

$result = $sts->getSessionToken(); 

$credentials = $result->get('Credentials'); 

print_r($credentials); 

?> 

然而，它造成此錯誤：

Uncaught exception 'Guzzle\Common\Exception\InvalidArgumentException' with message 'Command was not found matching GetSessionToken' in /home/site/public_html/dev/testAWS/core/aws/Guzzle/Service/Client.php:87 Stack trace: #0 /home/site/public_html/dev/testAWS/core/aws/Guzzle/Service/Client.php(76): Guzzle\Service\Client->getCommand('GetSessionToken', Array) #1 /home/site/public_html/dev/testAWS/core/aws/Aws/Common/Client/AbstractClient.php(105): Guzzle\Service\Client->__call('GetSessionToken', Array) #2 /home/site/public_html/dev/testAWS/core/ajax/test2.php(13): Aws\Common\Client\AbstractClient->__call('getSessionToken', Array) #3 /home/site/public_html/dev/testAWS/core/ajax/test2.php(13): Aws\S3\S3Client->getSessionToken() #4 {main} thrown in /home/site/public_html/dev/testAWS/core/aws/Guzzle/Service/Client.php on line 87 

的問題是這一行：

$result = $sts->getSessionToken(); 

我一直在關注本指南： http://docs.aws.amazon.com/AmazonS3/latest/dev/AuthUsingTempSessionTokenPHP.html

我看不到任何錯誤發生的原因。是否有任何理由或解決方法？

你在混合這個例子。 S3Client :: factory（）需要一個令牌作爲參數。你可能應該使用StsClient :: factory（）？
