Question

我正在尝试检索已邀请用户登录的事件。当我测试一些东西时，我在尝试这个FQL查询时遇到了这个错误：

public static List<GraphLocation> getEvents(Session session, Map<String, Object> queryParams){
    limpar();

    queryStringBuilder.append("SELECT eid, all_members_count, attending_count, declined_count, description, end_time, version, " +
                                     "name, location, pic, privacy, start_time, ticket_uri, timezone, unsure_count, venue " +
                              "FROM event");

    if(queryParams != null && !queryParams.isEmpty()){
        whereClause.append(" WHERE ");

        if(!queryParams.containsKey("dataInicio")){
            whereClause.append("start_time = " + formatter.format((Date) queryParams.get("dataInicio")));
        }
    }

    queryStringBuilder.append(whereClause.toString());

    Bundle params = new Bundle();
    params.putString("q", queryStringBuilder.toString());

    Request request = new Request(session, "/fql",  params, HttpMethod.GET, 
            new Request.Callback() {

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

    Request.executeBatchAsync(request);

    return null;
}
private static void limpar(){
    queryStringBuilder = new StringBuilder();
    whereClause = new StringBuilder();
}

如果有人能告诉我为什么会发生这个问题，我会非常高兴，无论如何，如果有人能解释我如何抓住特定用户被邀请参加的活动，我会更高兴。

非常感谢。

FQL查询需要一个WHERE语句，这是“意外的查询结束”异常的原因。

您正在寻找的查询是

SELECT eid, all_members_count, attending_count, declined_count, description, end_time, version, name, location, pic, privacy, start_time, ticket_uri, timezone, unsure_count, venue 
                FROM event WHERE eid IN ( SELECT eid FROM event_member WHERE uid = XXXXXXX ) 
                ORDER BY start_time asc

将XXXXXXX替换为facebook用户ID。

为了在将FQL查询集成到您的代码之前对其进行测试，您可以使用Facebook Graph API Explorer，例如here。

注意：不要忘记为您的Facebook应用添加“user_events”权限。
