如何使用新的Android SDK发送FQL查询

Question

我一直在寻找在developers.facebook网站寻找一种方式来使用新的SDK和发送FQL查询,但似乎一切都已经改变和文档都在谈论各种其他的方式来请求,me或者friends,但没有具体的信息,和那些使用我的应用程序的朋友一样？

所以我写下了一个不错的FQL查询

select uid, name, pic_square, is_app_user from user where uid in (select uid2 from friend where uid1 = me())

而现在,我所要做的就是运行它.

由于回复朋友列表的唯一请求似乎是好的Request.executeMyFriendsRequestAsync,Request.newMyFriendsRequest我认为他们是我的朋友,但两者都不允许微调FQL查询.

如何发送查询并获取朋友列表或至少一个JSONArray？

Hackbook - FQL查询教程使用旧版本的SDK,我不知道该怎么做.

更新:

我添加了这些代码行,以为它会让我创建这个查询:

public void onCreate(Bundle savedInstanceState) {
    // SOME CODE
    this.openSession();
}

protected void onSessionStateChange(SessionState state, Exception exception) {
    if (state.isOpened()) {
        Session activeSession = getSession().getActiveSession();
        facebook.setAccessToken(activeSession.getAccessToken());
        facebook.setAccessExpires(activeSession.getExpirationDate().getTime());

        Request req = Request.newMyFriendsRequest(activeSession, new GraphUserListCallback() {

            @Override
            public void onCompleted(List<GraphUser> users, Response response) {
                System.out.println(response.toString());

            }
        });
        Bundle params = new Bundle();
        params.putString("method", "fql.query");
        params.putString("query", "select uid, name, pic_square, is_app_user " + "from user where uid in "
                + "(select uid2 from friend where uid1 = me())");
        req.setParameters(params);
        Request.executeBatchAsync(req);

    }
}

我这样做了,以为它会编辑请求并添加我想要的信息,但是我收到了这个错误:

Answer 1

你会做这样的事情:

String fqlQuery = "select uid, name, pic_square, is_app_user from user where uid in (select uid2 from friend where uid1 = me())";
Bundle params = new Bundle();
params.putString("q", fqlQuery);

Session session = Session.getActiveSession();
Request request = new Request(session, 
    "/fql", 
    params, 
    HttpMethod.GET, 
    new Request.Callback(){ 
        public void onCompleted(Response response) {
        Log.i(TAG, "Got results: " + response.toString());
    }
});
Request.executeBatchAsync(request);

您基本上是向"/ fql"端点发出Graph API请求,并将查询传入"q"参数.
