Guzzle 6: no more json() method for responses

Previously in Guzzle 5.3:

$response = $client->get('http://httpbin.org/get');
$array = $response->json(); // Yoohoo
var_dump($array[0]['origin']);

I could easily get a PHP array from a JSON response. Now In Guzzle 6, I don't know how to do. There seems to be no json() method anymore. I (quickly) read the doc from the latest version and don't found anything about JSON responses. I think I missed something, maybe there is a new concept that I don't understand (or maybe I did not read correctly).

Is this (below) new way the only way?

$response = $client->get('http://httpbin.org/get');
$array = json_decode($response->getBody()->getContents(), true); // :'(
var_dump($array[0]['origin']);

Or is there an helper or something like that?

I use json_decode($response->getBody()) now instead of $response->json().

I suspect this might be a casualty of PSR-7 compliance.

You switch to:

json_decode($response->getBody(), true)

Instead of the other comment if you want it to work exactly as before in order to get arrays instead of objects.

I use $response->getBody()->getContents() to get JSON from response. Guzzle version 6.3.0.

If you guys still interested, here is my workaround based on Guzzle middleware feature:

Create JsonAwaraResponse that will decode JSON response by Content-Type HTTP header, if not - it will act as standard Guzzle Response:

<?php

namespace GuzzleHttp\Psr7;


class JsonAwareResponse extends Response
{
    /**
     * Cache for performance
     * @var array
     */
    private $json;

    public function getBody()
    {
        if ($this->json) {
            return $this->json;
        }
        // get parent Body stream
        $body = parent::getBody();

        // if JSON HTTP header detected - then decode
        if (false !== strpos($this->getHeaderLine('Content-Type'), 'application/json')) {
            return $this->json = \json_decode($body, true);
        }
        return $body;
    }
}

Create Middleware which going to replace Guzzle PSR-7 responses with above Response implementation:

<?php

$client = new \GuzzleHttp\Client();

/** @var HandlerStack $handler */
$handler = $client->getConfig('handler');
$handler->push(\GuzzleHttp\Middleware::mapResponse(function (\Psr\Http\Message\ResponseInterface $response) {
    return new \GuzzleHttp\Psr7\JsonAwareResponse(
        $response->getStatusCode(),
        $response->getHeaders(),
        $response->getBody(),
        $response->getProtocolVersion(),
        $response->getReasonPhrase()
    );
}), 'json_decode_middleware');

After this to retrieve JSON as PHP native array use Guzzle as always:

$jsonArray = $client->get('http://httpbin.org/headers')->getBody();

Tested with guzzlehttp/guzzle 6.3.3

Adding ->getContents() doesn't return jSON response, instead it returns as text.

You can simply use json_decode
