    }

    get(url): Promise
    {
        return this.http.get(Config.baseUrl + url).map(response => {
            return response.json() || {success: false, message: "No response from server"};
        }).catch((error: Response | any) => {
            return Observable.throw(error.json());
        }).toPromise();
    }

    post(url, data): Promise
    {
        return this.http.post(Config.baseUrl + url, data).map(response => {
            return response.json() || {success: false, message: "No response from server"};
        }).catch((error: Response | any) => {
            return Observable.throw(error.json());
        }).toPromise();
    }
}
