Flatmap 的用法的两个问题

[ihrthk]

subscription = fakeApi.getFakeToken("fake_auth_code")
                .flatMap(new Func1<FakeToken, Observable<FakeThing>>() { 
                    @Override 
                    public Observable<FakeThing> call(FakeToken fakeToken) { 
                        return fakeApi.getFakeData(fakeToken); 
                    } 
                }) 
                .subscribeOn(Schedulers.io()) 
                .observeOn(AndroidSchedulers.mainThread()) 
                .subscribe(new Action1<FakeThing>() { 
                    @Override 
                    public void call(FakeThing fakeData) {
//1.在这里怎么获取request httpurl
//List<Cookie> cookies = Cookie.parseAll(call.request().url(), response.headers());
//2.在这里怎么fakeToken数据，我要整合fakeToken和fakeData，一起返回
