I just tried another altrnative way by this options and directing posting String path Json to body of post method.

 getImage(path: string) {
            let headers = new Headers({ 'Content-Type': 'application/json' });
            let options = new RequestOptions({ headers: headers });

            return new Promise((resolve, reject) => {
                this.http.post('${apiUrl}',path, options)
                .map((res) => res.json()).share()
                .subscribe(res => {
                  resolve(res)
                }, (err) => {
                  reject(err);
                });
            });
          }

I would be happy if it works.Thanks
