java - Facebook 图形 API : Attend to event always returns responseCode: 200, false

Question

我正在尝试让 Facebook 用户参加一个 Activity ，

Request.executePostRequestAsync(...)

但是服务器总是返回以下内容:

{Response:  responseCode: 200, graphObject: GraphObject{graphObjectClass=GraphObject, state={"FACEBOOK_NON_JSON_RESULT":false}}, error: null, isFromCache:false}

身份验证有效，我可以获取用户信息等...我尝试用 Graph API Explorer 来拉索我的链接它在那里工作，所以我的代码应该有问题。我还检查了我的权限，它们都没有问题。如果有人可以帮助我，我会很高兴，这是我的代码:

List<String> permissions = new ArrayList<String>();
permissions.add("rsvp_event");

private void attendToEvent(final String eventID){
    Session.openActiveSession(MainActivity.this, true, new Session.StatusCallback() {

        @Override
        public void call(Session session, SessionState state, Exception exception) {

            Session actSession = Session.getActiveSession();
            if (!hasRSVPEventPermission() && actSession.isOpened()) {
                actSession.requestNewPublishPermissions(new Session.NewPermissionsRequest(MainActivity.this, permissions));
            }

            String accessToken = actSession.getAccessToken();
            String path = new String("https://graph.facebook.com/"+eventID+"/attending");
            if(session != null && session.isOpened()){
                JSONObject jo = new JSONObject();
                final GraphObject go = GraphObject.Factory.create(jo);
                Request.executePostRequestAsync(session, path, go, new Request.Callback() {
                //Request.executeGraphPathRequestAsync(session, path, new Request.Callback() {

                    @Override
                    public void onCompleted(Response response) {
                        System.out.println(response.toString());
                        showAttendResult(response.getGraphObject(), response.getError());
                    }
                });
            }
        }
    });
}

private boolean hasRSVPEventPermission() {
    Session session = Session.getActiveSession();
    return session != null && session.getPermissions().contains("rsvp_event");
}

我发现了!问题是，而不是这条路径:

String path = new String("https://graph.facebook.com/"+eventID+"/attending");

Graph API 期望这样:

String path = new String(eventID+"/attending");

所以没有“http://graph.facebook.com/”!
