angular - Нow 使用 angular-in-memory-web-api, angular2 更新数据库中的数据（文件 data.service.ts）

Question

Нow 使用 angular-in-memory-web-api 更新数据库中的数据（文件 data.service.ts）。在此代码中，我收到一条错误消息：“对‘所有者’ID 的请求与 item.id 不匹配”。同时，使用相同的链接删除工作_______________________________。

owner.component.ts

constructor(private http: HttpClient, private router: Router, private route: ActivatedRoute,
              private ownerService: OwnerService, private fb: FormBuilder) {

    this.subscription = route.params.subscribe(params => this.params.owner_id = params.id);
    console.log(this.params);


    this.form = this.fb.group({
      id: [this.params.owner_id, [Validators.required]],
      FirstName: ['', [Validators.required, Validators.minLength(3), Validators.maxLength(20)]],
    }); }

  ngOnInit(): void {................ }

  submit() {
    this.submitted = true;

    const car: Car = {
      number: this.form.value.number,
      brand: this.form.value.brand,
      model: this.form.value.model,
      year: this.form.value.year,
    };
    const car1 = [car];

    const owner: Owner = {
      id: this.form.value.id,
      FirstName: this.form.value.FirstName,
      LastName: this.form.value.LastName,
      MiddleName: this.form.value.MiddleName,
      cars: this.owner.cars?.concat(car1)
    };

    this.ownerService.editOwner(owner).subscribe(() => this.router.navigate(['']));
  }}

所有者服务.ts

 editOwner(owner: Owner): Observable<Owner> {
    console.log(owner.id);
    return this.http.put<Owner>(this.ownersUrl + owner.id, owner, this.httpOptions).pipe(
      catchError((error: HttpErrorResponse) => {
        console.error(error);
        return throwError(error);
      }));}

数据服务.ts

import {Injectable} from '@angular/core';
import {InMemoryDbService} from 'angular-in-memory-web-api';

@Injectable({
  providedIn: 'root'
})
export class DataService implements InMemoryDbService {
  constructor() {
  }

  createDb() {
    const owners = [
      {
        id: 1,
        LastName: 'Seaman Cap',
        FirstName: 'Seaman Cap',
        MiddleName: 'Lorem ipsum',
         cars: [{
          number: '1063uy',
          brand: 'BMW',
          model: 'optima',
          year: 2012,
        },
          {
            number: '1060uy',
            brand: 'kia',
            model: 'optima',
            year: 2010,
          },
        ]
      },]
    return {owners};
  }}
