我正在制作一个应用程序,用户可以在其中从他们的 Facebook 相册中选择一张照片。当他们选择相册时,我调用:'albumId + "/picture"' 以获取该相册中的照片列表。我必须添加一个检查 response.data[a].privacy == "everyone" 否则如果它的隐私设置是 "friends",则该相册不会返回任何照片。即使它是属于用户的相册并且用户创建了它,他们也无法从中选择照片。有什么我遗漏的或者这是 Facebook 的规则吗?

$('.btn-facebook').on('click', function (e) {
            e.preventDefault();

            var index = $(this).data('index');

            $("#albums").html("");
            albumsString = "<img src='/Content/images/albums.png' />";
            FB.login(function (response) {
                if (response.authResponse) {
                    var uid = response.authResponse.userID;

                    $.colorbox({
                        href: '/Game/Albums',
                        innerWidth: 488,
                        innerHeight: 588,
                        top: 0,
                        left: 0,
                        onComplete: function () {
                        }
                    });

                    FB.api('/me/albums', function (response) {
                        for (var a = 0; a < response.data.length; a++) {
                            if (response.data[a].count != null) {
                                if (response.data[a].count > 0) {
                                    if (response.data[a].privacy != null) {
                                        if (response.data[a].privacy == "everyone") {
                                            GetImg(response.data[a].id, index);
                                        }
                                    }
                                }
                            }
                        }
                    });

                } else {
                    alert('User cancelled login or did not fully authorize.');
                }
            }, { scope: 'email, user_likes, publish_actions, user_photos, friends_photos' });
        });
