Spring Social Facebookで FQL を使用して好きなものをすべて読みました
ここに方法があります:
public List<LikeObject> startF(String token){
Facebook facebook = new FacebookTemplate(token);
FacebookProfile profile = facebook.userOperations().getUserProfile();
//System.out.println(facebook.isAuthorized());
System.out.println("Authenticcated user: "+profile.getFirstName()+" "+profile.getLastName());
PagedList<String> friendListIds = facebook.friendOperations().getFriendIds();
List<LikeObject> resultsLikes = facebook.fqlOperations().query("SELECT object_id, object_id_cursor,object_type, post_id, post_id_cursor, user_id "+
"FROM like "+
"WHERE user_id =me() ", new FqlResultMapper<LikeObject>(){
public LikeObject mapObject(FqlResult result) {
LikeObject like = new LikeObject();
like.object_id = result.getString("object_id");
like.object_id_cursor = result.getString("object_id_cursor");
like.object_type = result.getString("object_type");
like.post_id = result.getString("post_id");
like.post_id_cursor = result.getString("post_id_cursor");
like.user_id = result.getString("user_id");
return like;
}
});
return resultsLikes;
}
結果は次のとおりです。
LikeObject [object_id=578416.., object_id_cursor=null, object_type=status, post_id=, post_id_cursor=null, user_id=10217..]
次に、like.object_id を解析して Java オブジェクトに変換したいと思います。しかし、春のソーシャルFacebookを使用してそれを行う方法がわかりません。
私は試しましfacebook.fetchObject(like.object_id, PostType.STATUS)
た。しかし、それは間違った方法のようです。
GET クエリから生の JSON 応答を解析せずに、Spring Social で「object_id」を解析する方法はありますか?
私はこれを試しました:
LinkPost post = facebook.fetchObject(obj_id, LinkPost.class);
obj_id のタイプはlinkだと思います。確認しました
次の例外が発生します。
