Retrieve the whole XML response body with Guzzle 6 HTTP Client

Question

I wanted to use Guzzle 6 to retrieve an xml response from a remote API. This is my code:

$client = new Client([
    'base_uri' => '<my-data-endpoint>',
]);
$response = $client->get('<URI>', [
    'query' => [
        'token' => '<my-token>',
    ],
    'headers' => [
        'Accept' => 'application/xml'
    ]
]);
$body = $response->getBody();

Vardumping the $body would return a GuzzleHttp\Psr7\Stream object:

object(GuzzleHttp\Psr7\Stream)[453] 
private 'stream' => resource(6, stream)
...
...

I could then call $body->read(1024) to read 1024 bytes from the response (which would read in xml).

However, I'd like to retrieve the whole XML response from my request since I will need to parse it later using the SimpleXML extension.

How can I best retrieve the XML response from GuzzleHttp\Psr7\Stream object so that it is usable for parsing?

Would the while loop the way to go?

while($body->read(1024)) {
    ...
}

I'd appreciate your advice.

Answer 1

$client = new \GuzzleHttp\Client();
$response = $client->request('GET', $request_url, [
    'headers' => ['Accept' => 'application/xml'],
    'timeout' => 120
])->getBody()->getContents();

$responseXml = simplexml_load_string($response);
if ($responseXml instanceof \SimpleXMLElement)
{
    $key_value = (string)$responseXml->key_name;
}

Answer 2

$client = new \GuzzleHttp\Client();
$response = $client->request('GET', 'your URL');
$response = $response->getBody()->getContents();
return $response;
