Question

我的Ioinc 4在chrome和firefox浏览器上运行，但是cors在android 9上无法正常工作。我的Http标头在下面。

    intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

常量令牌= localStorage.getItem（'access_token'）; this.loaderService.show（）;

    if (token) {
      request = request.clone({ setHeaders: { 
        'Authorization': token, 
        'Accept': 'application/json',
        'Access-Control-Allow-Origin':'*',
        'Access-Control-Allow-Methods':'*',
        'Access-Control-Allow-Headers': '*',
      }});
    } else {
      request = request.clone({ setHeaders: { 
        'Accept': 'application/json',
        'Access-Control-Allow-Origin':'*',
        'Access-Control-Allow-Methods':'*',
        'Access-Control-Allow-Headers': '*',
      }});
    }
    return next.handle(request).pipe(
      map((event: HttpEvent<any>) => {
        return event;
      }),
      catchError((error: HttpErrorResponse) => {
        return throwError(error);
      }),
      finalize(() => { 
        this.loaderService.hide();
       }));
  }
