Question

我想从AWS获取实例。

这是我的功能：

$ec2Client = Ec2Client::factory(array(
'version' => '2015-10-01',
'region'  => 'us-east-1',
'credentials' => array(
'key' => 'key',
'secret'  => 'secret',
)
));
$result = $ec2Client->DescribeInstances();

我希望在http://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeInstances.html?r=2119#API_DescribeInstances_Errors中指定以下结果：

<DescribeInstancesResponse xmlns="http://ec2.amazonaws.com/doc/2015-10-01/">

        </instancesSet>
      </item>
    </reservationSet>
    </DescribeInstancesResponse>

但我得到以下结果：

Aws\Result Object ( [data:Aws\Result:private] => Array ( [Reservations] => Array ( ) [@metadata] => Array ( [statusCode] => 200 [effectiveUri] => https://ec2.us-east-1.amazonaws.com [headers] => Array ( [content-type] => text/xml;charset=UTF-8 [transfer-encoding] => chunked [vary] => Accept-Encoding [date] => Fri, 27 Nov 2015 07:03:59 GMT [server] => AmazonEC2 ) ) ) )

我不知道如何获得预期的结果。我可以得到任何帮助吗？

感谢。

这里有两件事：

您拥有AWS SDK，这是您在第一个链接中列出的
您拥有构建于AWS SDK之上的PHP SDK。

通过PHP SDK时，您将不会收到SDK答案（即XML）。有关PHP sdk返回的内容，请参阅http://docs.aws.amazon.com/aws-sdk-php/v3/api/api-ec2-2015-10-01.html#describeinstances。

从AWS获取实例 - Amazon Web Services
