Am trying to post data to php backend and display json call response
message *success* but am having the following errors
*Error in src/app/car.service.ts(42,5): error type*
*observable<Object> is not assignable to type Observable<String>*
Here is *app.component.ts* code
import { Component, OnInit } from '@angular/core';
import { Car } from './car';
import { CarService } from './car.service';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
//cars: Car[];
cars: Car="";
error = '';
success = '';
car = new Car('', 0);
constructor(private carService: CarService) {
}
ngOnInit() {
//this.getCars();
}
public regCar(r) {
this.resetErrors();
this.carService.store1(this.car)
.subscribe(
res => {
alert(res);
if (res === 'success') { // or this.cars['message']
// Inform the user
this.success = 'Created successfully';
}
// Reset the form
r.reset();
},
err => this.error = err
);
}
private resetErrors(){
this.success = '';
this.error = '';
}
}
Here is the *Car.services.ts*
import { Injectable } from '@angular/core';
import { HttpClient, HttpErrorResponse, HttpParams } from
'@angular/common/http';
import { Observable, throwError } from 'rxjs';
import { map, catchError } from 'rxjs/operators';
import { Car } from './car';
@Injectable({
providedIn: 'root'
})
export class CarService {
baseUrl = 'http://localhost/angular-project1/api';
//cars: ;
//cars: Car[];
constructor(private http: HttpClient) { }
store1(car: Car): Observable<String> {
return this.http.post(`${this.baseUrl}/store1`, { data: car })
.pipe(
catchError(this.handleError));
}
private handleError(error: HttpErrorResponse) {
console.log(error);
// return an observable with a user friendly message
return throwError('Error! something went wrong.');
}
}
here is the* car.ts*
*export class Car { constructor( model: string, price: number,
id?: number) {}}store.php*
*// pass parameter here*
*$car = [*
* 'message' => 'success'*
* ];*
* echo json_encode($car);*
* }*
* else*
* {*
* http_response_code(422);*
* }*
