How to extract CouchDB cookie from Httpful response object in PHP?

Question

I try to authenticate a user via a RESTful API in combination with CouchDB and Httpful.

The client sends the credentials of the user to my server and the server forwards them to the CouchDB server.

When I var_dump the response, I can see that the content is there but I can't extract the cookie which I would like to send back to the client.

Authenticate function on my Server:

public function authenticate($request, $response)
{             
    $username = $request->getParsedBody()['username']; 
    $password = $request->getParsedBody()['password']; 

    $uri = "http://localhost:5984/_session";

    $sessionToken = \Httpful\Request::post($uri)    
        ->sendsJson()                                 
        ->body('{"name":"'.$username.'", "password":"'.$password.'"}')
        ->send();                                   

    $cookie = $sessionToken->headers->headers[6];

    return $response->withHeader('Set-Cookie', $cookie);
}

The response object:

object(Httpful \ Response) # 56(13) {
    ["body"] => object(stdClass) # 58(3) 
        ...

    ["raw_body"]
        ...

    ["headers"] => object(Httpful \ Response \ Headers) # 57(1) {
        ["headers": "Httpful\Response\Headers": private] => array(6) {
            ...
            ["set-cookie"] => string(85)"AuthSession=abc123; Version=1; Path=/; HttpOnly"
        }
    }

    ["raw_headers"]
        ...

    ["code"]
        ...
}

Error message:

Cannot access private property Httpful\Response\Headers::$headers

I would like to know how I could access the Set-Cookie attribute with Httpful. I browsed the web on this issue and unfortunately it seems that I'm the only one who is facing this particular problem.

I found a solution:

I just needed to add these two lines to my authentication controller:

$myArray = array_values($sessionToken->_parseHeaders($sessionToken->raw_headers));

$cookie = $myArray[5];

The _parseHeaders I found within the API documentation from Httpful and played around with it in combination with array_values.

An instance of Headers-class is set into $sessionToken->headers, that you can just access like an array.

The set-cookie header you get with this:

$sessionToken->headers['set-cookie'];
