You can handle with the catch operator and throw error which matches with the error code status import {Observable} from 'rxjs/Rx'; return this .http.request( new Request( this .requestoptions)) .map((res: Response) => { if (res) { if (res.status === 201) { return [{ status: res.status, json: res }] } else if (res.status === 200) { return [{ status: res.status, json: res }] } } }). catch ((error: any) => { if (error.status === 500) { return Observable. throw ( new Error(error.status)); } else if (error.status === 400) { return Observable. throw ( new Error(error.status)); } else if (error.status === 409) { return Observable. throw ( new Error(error.status)); } else if (error.status === 406) { return Observable. throw ( new Error(error.status)); } }); } You can handle the error that is thrown by catch block in the function like below .subscribe(res=>{....} err => { //handle the error});
