Laravel Cookie and Angular 2 /4

Hi, I used laravel as backend (that implemented at homestead - mydomain.test) and angular 4 as frontend (that implemented at http://localhost:4200), now, I want to set a cookie from backend to frontend browser. backend controller:

return response(['access_token'=>$response['access_token'], 'expires_in' => $response['expires_in']])
          ->withCookie($cookie);

and response is:

Access-Control-Allow-Origin:*
Cache-Control:no-cache, private
Connection:keep-alive
Content-Type:application/json
Date:Sat, 30 Dec 2017 09:01:11 GMT

Transfer-Encoding:chunked

X-RateLimit-Remaining:59

but when I want to send the cookie from frontend to backend , it does not work! I used angular 4:

refreshToken(){

    const headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded', 'Authorization': 'Bearer ' + this.getToken()})
    let options = new RequestOptions({ headers: headers, withCredentials: true });

    return this.http.post(API_DOMAIN + 'refresh', JSON.stringify({}), options)
      .map(
        (response) => {
          console.log(response.json());
          return response.json()
        },
      )
  }

and backend side:

    $refreshToken = $request->cookie(self::REFRESH_TOKEN);
    var_dump($refreshToken); // to be null always

can you help me how to solve these problems?
