Guzzle OAuth 1.0 problem with headers, 401 Bad request - guzzle

Question

I'm trying to replace my own cURL code to the Guzzle client, but for some reason I can't get it to work, this is the cURL request and is perfectly fine:
curl_setopt_array($curl, array(
CURLOPT_URL => $this->url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => $this->method,
CURLOPT_HTTPHEADER => array(
'Authorization: OAuth realm="' . $this->realm . '",oauth_consumer_key="' . $this->consumerkey . '",oauth_token="' . $this->tokenid . '",oauth_signature_method="HMAC-SHA256",oauth_timestamp="' . $this->timestamp . '",oauth_nonce="' . $this->nonce . '",oauth_version="1.0",oauth_signature="' . $this->signature . '"',
'Cookie: NS_ROUTING_VERSION=LAGGING'
),
));
replacing it with:
$this->headers['Authorization'] = 'OAuth realm="' . $this->realm . '";oauth_consumer_key="' . $this->consumerkey . '";oauth_token="' . $this->tokenid . '";oauth_signature_method="HMAC-SHA256";oauth_timestamp="' . $this->timestamp . '";oauth_nonce="' . $this->nonce . '";oauth_version="1.0";oauth_signature="' . $this->signature . '"';
$this->headers['Cookie'] = 'NS_ROUTING_VERSION=LAGGING';
$request = new Request($type, $method, ['headers' => $this->headers], $body);
The response I get is 401 bad request, meaning that the authorisation is invalid.
Anyone know how to fix? Much appreciated.

You can try like this.
use GuzzleHttp\Psr7\Request;
$client = new \GuzzleHttp\Client();
$headers['Authorization'] = 'OAuth realm="' . $this->realm . '";oauth_consumer_key="' . $this->consumerkey . '";oauth_token="' . $this->tokenid . '";oauth_signature_method="HMAC-SHA256";oauth_timestamp="' . $this->timestamp . '";oauth_nonce="' . $this->nonce . '";oauth_version="1.0";oauth_signature="' . $this->signature . '"';
$headers['Cookie'] = "NS_ROUTING_VERSION=LAGGING";
$response = $client->request('YOUR HTTP METHOD HERE', 'YOUR URL', );
$request = new Request('YOUR HTTP METHOD HERE', 'YOUR URL');
$response = $client->send($request,
['headers' => $headers,
'body' => $body, //should be array
]);
print_r($response);
