Question

我的应用程序在chrome中完美运行但在Mozilla firefox中加载应用程序时，它在控制台中的服务调用时抱怨以下内容............任何帮助都将受到高度赞赏

EXCEPTION: Uncaught (in promise): TypeError: You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array, or Iterable.

以下是我用来调用服务的代码。此调用在Chrome / IE中完全正常

headers = new Headers();
  constructor(private http:Http) {
    this.headers.append('content-type', 'application/json');
    this.headers.append('Accept', 'q=0.8;application/json;q=0.9');
  }
  getFundingRequestData() {
    return this.http.get(this.Url).map((res:Response) => res.json()).catch((err:any) => err);
  }

角度2不在Mozilla Firefox中工作，但在chrome中工作
