Stream PDF file

[cierzniak]

Hi,
I can't handle this for two days. I need help! If it's related to #230, does it could be merged?

I have Guzzle request with stream => true option to fetch PDF file from external API. Request via browser or Postman works with success, tests in PHPUnit works, but tests in PHPUnit with PHP-VCR fails.

I still have array_shift() expects parameter 1 to be array, null given at https://github.com/guzzle/guzzle/blob/master/src/Handler/StreamHandler.php#L100

Can you point me where is the trouble?

tests/WebTestCase.php

    protected function setUp(): void
    {
        parent::setUp();
        $this->runCommand('doctrine:migrations:migrate --no-interaction');
        VCR::configure()->enableLibraryHooks(['curl'])->setStorage('yaml');
        VCR::getEventDispatcher()->addListener(VCREvents::VCR_BEFORE_HTTP_REQUEST, [$this, 'setCustomHeaders']);
        VCR::getEventDispatcher()->addListener(VCREvents::VCR_BEFORE_PLAYBACK, [$this, 'setCustomHeaders']);
        $this->client = $this->createClient();
    }

    public function setCustomHeaders(Event $event, $eventName): void
    {
         // It's needed to be agnostic of PHP, Guzzle and PHPUnit version
        /** @var Request $request */
        $request = $event->getRequest();
        $request->setHeader('User-Agent', 'VCR_user_agent');
    }

    {
        $this->client->getCookieJar()->set(new Cookie('X-Authorization', $token));

guzzle action

    private function fetchData(string $url, array $queryParams = [], array $headers = []): array
    {
        $response = $this->guzzle->request('GET', $url, ['stream' => true, 'query' => $queryParams]);
        if ($response->getStatusCode() === Response::HTTP_OK) {
            return [
                'body' => $response->getBody(),
                'headers' => array_reduce($headers, function ($result, $header) use ($response) {
                    $result[$header] = $response->getHeader($header);

                    return $result;
                }, ['Content-Transfer-Encoding' => 'binary']),
            ];
        }
        $content = json_decode($response->getBody()->getContents(), true);

        throw new ApiException(
            $content['errors']['message'],
            $content['errors']['code'] ?? $response->getStatusCode()
        );
    }
