OAuth 1.0 one-legged client “HTTP 401 Unauthorized error” for PATCH method

Question

This is the first time I'm using OAuth and I created the class below which partially works! I followed this manual .

Methods methodGet() and methodPost() work fine however methodPatch() returns "HTTP 401 Unauthorized error". End-point expects a PATCH request method and since there is no constant for PATCH in OAuth class , I'm trying to send a POST request and trying to override it with an extra X-Http-Method-Override header so that it becomes a PATCH method behind the scene (may be not!!!). That's the problem, I cannot PATCH it!

As it is highly likely to do with PATCH (GET and POST work fine), does anyone know a solution to it or am I missing something else?

Note: I can confirm that the end-point works fine so there is no problem at that side.

Thanks in advance

            return json_decode($oAuth->getLastResponse(), true);

        }
    }

Solution was to use Guzzle Client so the method is below:

Note: $authHeader holds $oauth->getRequestHeader(...); so you can generate it and pass it to the method.

private function call($uri, $method, $authHeader, array $payload = [])
{
    try {
        $client = new Client();
        $request = $client->createRequest($method, $uri);
        $request->addHeader('Authorization', $authHeader);
        $request->addHeader('Content-Type', 'application/json');
        $request->setBody(Stream::factory(json_encode($payload)));
        $response = $client->send($request);
    } catch (RequestException $e) {
        $message = $e->hasResponse()
            ? $e->getResponse()
            : 'An unknown error occurred while trying to process your request.';

        throw new Exception($message);
    }

    return json_decode($response->getBody(), true);
}
