Angular 6 httpClient Post with credentials

In order to request with cookies you will need to add withCredentials in your request. See following code

const httpOptions = {
 headers: new HttpHeaders({
  'Authorization': fooBarToken
 }),
 withCredentials: true
};

The following code works too:

return this.http.get<{}>('YOU API URL', {
      withCredentials: true
 })
