如何使用angular httpModule访问json中的嵌套节点？

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) { }
}

this.http.get('path/to/json/file.json').subscribe(data => {
  // 处理返回的JSON数据
});

{
  "user": {
    "name": "John",
    "age": 25
  }
}

this.http.get('path/to/json/file.json').subscribe(data => {
  const userName = data.user.name;
  const userAge = data.user.age;
  // 使用获取到的数据进行其他操作
});
