我们如何改变基于angular-in-memory-web的url？

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

@Injectable({
  providedIn: 'root',
})
export class InMemoryDataService implements InMemoryDbService {
  createDb() {
    const items = [
      { id: 1, name: 'Item 1' },
      { id: 2, name: 'Item 2' },
      // ... more items
    ];
    return { items };
  }

  // 自定义URL路径
  genId(items: any[]): number | undefined {
    return Math.floor(Math.random() * 1000);
  }

  // 可以在这里添加更多的自定义方法来处理特定的URL请求
}

import { HttpClientModule } from '@angular/common/http';
import { HttpClientInMemoryWebApiModule } from 'angular-in-memory-web-api';
import { InMemoryDataService } from './in-memory-data.service';

@NgModule({
  imports: [
    HttpClientModule,
    HttpClientInMemoryWebApiModule.forRoot(InMemoryDataService, { dataEncapsulation: false })
  ],
  // ... other module properties
})
export class AppModule { }

get_itemById(id: number): any {
  return { id, name: `Item ${id}` };
}

this.http.get(`/items/${id}`).subscribe(item => {
  console.log(item);
});
