Question

我有以下查询获得500错误。我认为这是因为权限，但我设置了user_likes和friends_likes permisssions。

SELECT user_id, url FROM url_like WHERE strpos(url,'myurl') AND user_id IN (SELECT uid2 FROM friend WHERE uid1 = me())

这个工作正常。

SELECT user_id, url FROM url_like WHERE strpos(url,'myurl') AND user_id = me()

任何想法为什么我不能让我的朋友喜欢某个网址？我知道可以做到。我看过很多显示数据的其他网站。

我在c＃中这样做。我的第二个查询现在被注释掉，直到我得到第一个工作。

dynamic resultLikes = fb.Get("fql",
                 new
                 {
                     q = new
                     {
                         urlLikes = "SELECT user_id, url FROM url_like WHERE strpos(url,'myUrl') AND user_id IN (SELECT uid2 FROM friend WHERE uid1 = me())",
                         //resultLike = "SELECT uid, name, pic_small FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me() AND (uid2 IN (SELECT user_id FROM #urlLikes)))",
                     }
                 });

我将发布代码，希望有人知道出了什么问题。我尝试过两种不同的方式。

首先使用Httpwebrequest：

 private void GetMyLikes()
    {
        //string URL = "https://graph.facebook.com/" + userID + "/picture";

        string url = String.Format("https://api.facebook.com/method/fql.query?query=SELECT user_id, url FROM url_like WHERE user_id IN (SELECT uid2 FROM friend WHERE uid1 = me())&access_token={0}&format=json", accessToken);

        HttpWebRequest req = (System.Net.HttpWebRequest)HttpWebRequest.Create(url);
        req.AllowWriteStreamBuffering = true;
        req.Timeout = 200000;

        HttpWebResponse  resp = req.GetResponse() as HttpWebResponse;
        StreamReader reader = new StreamReader(resp.GetResponseStream());
        string likes = reader.ReadToEnd();

        resp.Close(); 

    }

使用C＃SDK

private void getFriendsProductLikes()

{

if (!string.IsNullOrWhiteSpace(accessToken))
    {
    FacebookClient fb = new FacebookClient(accessToken);                    

    dynamic resultLikes = fb.Get("fql", new { q = "SELECT user_id, url FROM url_like WHERE user_id IN (SELECT uid2 FROM friend WHERE uid1 = me())" });

        }

}

我目前可能拥有的设置权限超出了我的需要。

public const string SCOPE = "user_likes,friends_likes,user_status,friends_status,publish_actions,user_location,friends_location,user_checkins,friends_checkins,read_stream,user_activities,friends_activities,user_birthday,friends_birthday,user_about_me";

谢谢，
