php - Facebook API 返回未捕获异常：604：您的语句不可索引

Question

我目前正在制作一个应用程序，它将阅读我墙上的一些帖子。问题是我不断收到此错误

Fatal error: Uncaught Exception: 604: Your statement is not indexable. The WHERE clause must contain an indexable column. Such columns are marked with * in the tables linked from http://developers.facebook.com/docs/reference/fql thrown in \application\libraries\base_facebook.php on line 1238

我已经拥有这些权限，我什至在我的应用程序设置中添加了一些其他权限。read_stream offline_access read_insights

AppId、secret 和 access_token 都设置好了。

更新：现在，当我将查询更改为此时，API 返回一个不同的错误

$fql = "SELECT post_id, actor_id, target_id, message FROM stream WHERE source_id = me() AND created_time > 1346277600 LIMIT 50";

更新：我现在收到此错误

Fatal error: Uncaught Exception: 102: Requires user session thrown in \application\libraries\base_facebook.php on line 1238

Answer 1

看 ：

http://developers.facebook.com/docs/reference/fql/stream/

只有少数字段是可索引的，因此应在whereFQL 的子句中使用其中之一。您的查询似乎对我来说很好。

https://api.facebook.com/method/fql.query?query=SELECT%20post_id%2C%20actor_id%2C%20target_id%2C%20message%20FROM%20stream%20WHERE%20source_id%20%3D%20me%28% 29%20AND%20created_time%20%3C%201346647136%20LIMIT%2050&access_token=ACCESS_TOKEN_HERE

Answer 2

我只是忘了把access_tokenat the facebook->api call

$data['posts'] = $this->facebook->api(array(
                   'method' => 'fql.query',
                   'query' => $fql,
                   'access_token'=>$facebook['access_token']
                 ));
