Question

我当前正在尝试在http请求之后返回Angular中的Observable。以下是方法代码：

public   fetchOptions(options ?: any): Observable<any> {

  let response: Subject<Response> = new Subject<Response>();
  if (!this._config) {
      return null;

 }
let requestOptions: any= null;
// fetch Token from oag and add the Authorisation Header
this.fetchToken().subscribe((token: IOagAccessTokenResponse) => {
    let finalOptions: any= {};
    if (options) {
        finalOptions = options;
    }

    if (!finalOptions.headers) {
        finalOptions.headers = new HttpHeaders();
    }
    // first remove Header and after this add the new header
   finalOptions.headers = finalOptions.headers.delete('Authorization');

   requestOptions = finalOptions;

   }), (e): any=> {

  };

 return TimeoutedObservable.complete(requestOptions);

}

这是上面的TimeoutedObservable.complete（）函数的代码，该函数创建并返回一个Observable：

private static timeout: number = 300;

public static complete(obj: any): Observable<any> {
    return TimeoutedObservable.completeWithTime(TimeoutedObservable.timeout, 
obj);
}

public static completeWithTime(time: number, obj: any): Observable<any> {
    let observable: BehaviorSubject<any> = new BehaviorSubject<any>(obj);
    setTimeout(()=> {
    observable.complete()
    }, time);
    return observable;
}

这是对此函数的订阅调用： this.fetchOptions（options）.subscribe（（requestOptions：any）=> { ..... }

此代码在Chrome中有效，但在IE 11中，我收到以下错误：由fetchOptions（）函数返回的被订阅的对象requestOptions为空。如何使此代码在IE 11中正常工作？
