angular - 如何将结构化数据转化为可观察数据？

Question

我有一个 Web API 返回一些结构化数据。

{
    i: {
        f: [...],
        a: val,
        b: val
    },
    a: [...],
    b: [...],
    c: [...]
}

我将其返回到 Angular 6 应用程序 - 我假设使用 Observables 和 rxjs。我看到的所有可观察值的示例都假设一个数组被转换为可观察值。但是，该数据是结构化的，并且在结构中包含一些子数组。

我是 Angular 的新手，所以如果可能的话，我正在寻找一些方向。

服务:

import {
    HttpClient,
    HttpErrorResponse,
    HttpEvent,
    HttpHandler,
    HttpInterceptor,
    HttpRequest,
    HttpHeaders
} from '@angular/common/http';

constructor(private httpClient: HttpClient,
        ) {
    }

    /**
     * This method is use for send GET http Request to API.
     * @param url - Additional request URL.
     * @param options  - Header(s) which will pass with particular request.
     */
    get(url: string, options?: any): Observable<any> {

        return this.httpClient.get(url, this.requestOptions(options))
    }





   /**
    * Request options.
    * @param headerOptions
    * @returns {RequestOptionsArgs}
    */
    private requestOptions(headerOptions?: any): any {
        options = {
                    headers: new HttpHeaders({
                        "Authorization": "Bearer " + token,
                        "Content-Type": "application/json"
                    })
                }
             }

组件.ts:

 myData: Array<any>;

    /**
     * This method is used to get  data
     */
    getFormData(filter) {

        this.requestURL = `your_url`;

         this.http.get(this.requestURL, options).subscribe(response => {

              this.myData = response as ArrayCast[]
              console.log(response)
            })
           ;
    }

export class ArrayCast{
  a: any;
  b: any;
  c: any;
}
