如何在Angular 湖北福彩中调用多个Rest API并进行订阅？

I have multiple methods that contain individual get method but in component How to Call Multiple Rest API and Subscribe in component i.e. calling multiple methods in one subscribe.

  /**
   * Get current User from the server.
   *
   * @returns {json} current user.
   */
  public getCurrentUser(): any {
    return this.http.get(this.baseUrl)
      .pipe(map((res: any) => res.data));
  }
  /**
   * Get all device statuses from the server.
   *
   * @returns {json} all asset statuses.
   */
  public getDeviceConditions(): any {
    return this.http.get(this.baseUrl)
      .pipe(map((res: any) => res.data));
  }

假设我想用一个订阅调用以上两种方法。
