在Angular中处理来自服务器路由/控制器的更新

import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    HttpClientModule
  ],
  // ...
})
export class AppModule { }

import { HttpClient } from '@angular/common/http';

@Component({
  // ...
})
export class MyComponent {
  constructor(private http: HttpClient) { }

  updateResource() {
    this.http.get('/api/resource').subscribe(response => {
      // 处理响应数据
    });
  }
}

import { map } from 'rxjs/operators';

// ...

updateResource() {
  this.http.get('/api/resource').pipe(
    map(response => response as MyResource)
  ).subscribe(resource => {
    // 处理转换后的资源对象
  });
}

updateResource() {
  const updatedResource = { /* 更新的资源数据 */ };

  this.http.put('/api/resource', updatedResource).subscribe(response => {
    // 处理更新成功的响应
  });
}
