Make POST request to create new post in topic

sendPostMessage(message: Message, user: User): Observable<Message> {
        let headers = new Headers({
          'Content-Type': 'multipart/form-data',
          'Access-Control-Allow-Credentials': 'true',
          'Access-Control-Allow-Origin': '*',
          'cache-control': 'no-cache',
          'Access-Control-Allow-Methods': 'POST, OPTIONS',
        });
        let messageBody = {
          topic_id: message.topic_id,
          raw: message.raw,
          api_key: user.api_key,
          api_username: user.api_username
        }
        let options = new RequestOptions({ headers });
        return this.http.post('http://dogwelder.pocketgems.com/posts' , messageBody, options)
            .map(this.extractData)
            .catch(this.handleErrorObservable);
