Javascript 组合从json文件中剔除的多个对象，并作为可观察对象返回

我想将对象

this.webCustomAlert

，

this.webCustomAuth

，

this.webcustomecomerce

组合成一个对象。它们都具有共同的性质。因此，我想从以下几点开始：

webCustomAuth

[{ "type":"google-login", "cost":30, "buildTime":2 },{ "type":"twitter-login", "cost":30, "buildTime":2 },{ "type":"facebook-login", "cost":30, "buildTime":2 }]

webCustomAlert

[{ "type":"desktop-notifications", "cost":30, "buildTime":2 },{ "type":"web-notification-page", "cost":30, "buildTime":2 },{ "type":"web-notification-settings", "cost":30, "buildTime":2 }]

网络定制商务

[{ "type":"affiliate-url", "cost":30, "buildTime":2 },{ "type":"coupons", "cost":30, "buildTime":2 },{ "type":"discounts", "cost":30, "buildTime":2 }]

到

webCustomFeatures

[{ "type":"affiliate-url", "cost":30, "buildTime":2 },{ "type":"coupons", "cost":30, "buildTime":2 },{ "type":"discounts", "cost":30, "buildTime":2 },{ "type":"desktop-notifications", "cost":30, "buildTime":2 },{ "type":"web-notification-page", "cost":30, "buildTime":2 },{ "type":"web-notification-settings", "cost":30, "buildTime":2 },{ "type":"google-login", "cost":30, "buildTime":2 },{ "type":"twitter-login", "cost":30, "buildTime":2 },{ "type":"facebook-login", "cost":30, "buildTime":2 }]

这是我的密码：

  public webCustomFeatures: any;
  public webCustomAlert: any;
  private webCustomAlertDataPath = './assets/data/web-custom-alert.json';
  public webCustomAuth: any;
  private webCustomAuthDataPath = './assets/data/web-custom-auth.json';
  public webCustomEcommerce: any;
  private webCustomEcommerceDataPath = './assets/data/web-custom-ecommercejson';

  constructor(
    public httpClient: HttpClient
  ) {
    this.webCustom = this.httpClient.get(this.webCustomDataPath);
    this.webCustomAlert = this.httpClient.get(this.webCustomAlertDataPath);
    this.webCustomAuth = this.httpClient.get(this.webCustomAuthDataPath);
    this.webCustomEcommerce = this.httpClient.get(this.webCustomEcommerceDataPath);
  }

  public getAllWebCustomAlert(): Observable<any> {
    return this.webCustomAlert;
  }

  public getAllWebCustomAuth(): Observable<any> {
    return this.webCustomAuth;
  }

  public getAllWebCustomEcommerce(): Observable<any> {
    return this.webCustomEcommerce;
  }

  public getAllWebCustomFeatures(): Observable<any> {
    const webCustomFeatures = [];
    webCustomFeatures.push(this.webCustomAlert);
    webCustomFeatures.push(this.webCustomAuth);
    webCustomFeatures.push(this.webCustomEcommerce);
    return webCustomFeatures;
  }

}

我一直收到错误消息

类型“any[]”不能分配给类型“Observable”。类型“any[]”中缺少属性“\u isScalar”。

如果返回的是一个不可观测的可观测数组，则要组合相关测试

public getAllWebCustomFeatures(): Observable<any> {
  return combineLatest(this.webCustomAlert, this.webCustomAuth, this.webCustomEcommerce);
}

getAllWebCustomFeatures().subscribe(([webCustomAlert, webCustomAuth, webCustomEcommerce]) => {
  //Do stuff with the destructured values here
});
