  constructor(
      private config  :  ConfigService,
      private http: Http){


     this.getWS('ngoName')
      .do((data) => {
        console.log(data);
        this.saveObj(data);
      }).toPromise();




}

saveObj(data:any){
  this.profileObj = data;

  console.log(this.profileObj);

}


  getWS(ngoName:string):any{


    return this.http.get(this.config.serverBaseURL + "ngos.php?ngoId=1")
        .map((res: Response) => res.json());

  }

{ "statusCode" : "200", "message" : "success", "ngoDetails" : [ {"ngoId":"1","ngoName":"Test 1","emailId":"ritesh@gmail.com"}]}
