Though a late answer, I found angular UrlSearchParams worked very well for me, it takes care of the encoding of parameters as well.

let params = new URLSearchParams();

let headers = new Headers({ 'Content-Type': 'application/x-www-form-urlencoded'});
let options = new RequestOptions({ headers: headers, withCredentials: true });
this.http
.post(UrlUtil.getOptionSubmitUrl(parentSubcatId), params, options)
.catch();
