适用于PHP 2的AWS S3 SDK - 获取HTTP请求/响应字符串

Question

I have a generic HTTP file access API which I use for the system I'm working on. To make it as flexible as possible, it returns request and response data in the form of HTTP strings.

I'm currently implementing a version which interacts with the S3, via the AWS SDK for PHP 2.

Is there an easy way to quickly get the Request and Response HTTP requests which the S3Client makes when performing operations? If not, is there a more piecemeal way which I can use to not have to fake it?

Basically, I'd like the full-text of both the Request and Response on demand, or at least access to relevant data (headers, response codes, URLs, etc) so I can properly populate the return data for my framework.

Thanks.

You can get either the request or response object from a command object. Assuming $s3 holds an instance of Aws\S3\S3Client, you could do something like this:

$command = $s3->getCommand('ListObjects', array('Bucket' => '<bucket-name>'));
$request = $command->getRequest();
$response = $command->getResponse();

Those objects have methods for viewing the body, headers, status codes, etc. and you can cast them to string to see the string form.

If you want to quickly see the request and response as you are executing commands, you can attach the wire logger, and see what comes out on STDOUT (or STDERR)

$s3->addSubscriber(\Guzzle\Plugin\Log\LogPlugin::getDebugPlugin());
$s3->listObjects(array('Bucket' => '<bucket-name>'));
