Facebook graph api 带有FQL批处理请求的Facebook Graphi API

我试图在java中对graph API使用批处理请求。实际上是一个HTTPClient发出了一个graphapi请求

我尝试构建一个批处理请求数组，如下所示：

String query2 = "SELECT --- from tableX";

    String query = "SELECT --- from tableY";

    String batch_request= "[{\"method\":\"GET\",\"relative_url\":method/fql.query?query="+query+"},"+
    "{\"method\":\"GET\",\"relative_url\":method/fql.query?query="+query2+"}]";

然后我对请求进行URLEncode:stringquery=URLEncoder.encode（批处理请求）

并将其传递给graph API，如下所示： “+query+”&access_-token=“+accessToken”

我没有得到任何结果：（。它返回错误500

有什么想法吗？

对于fql查询的批处理请求，您可以这样做。我已经成功地尝试过了

//$current_user=facebook id

 $query1="SELECT uid, name FROM user WHERE is_app_user=1 AND uid IN (SELECT uid2 FROM friend WHERE uid1 = $current_user)";
 $query2="SELECT uid, name, work_history FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = $current_user )";
 $query3="SELECT uid, name, work, education FROM user WHERE uid = $current_user";
 $queries = array(
           array('method'=>'GET', 'relative_url'=>'method/fql.query?query='.str_replace(' ','+',$query1)),
           array('method'=>'GET', 'relative_url'=>'method/fql.query?query='.str_replace(' ','+',$query2)),
           array('method'=>'GET', 'relative_url'=>'method/fql.query?query='.str_replace(' ','+',$query3))
            );

            $objs = $facebook->api('/?batch='.json_encode($queries), 'POST');

$objs获取整个查询结果的json数组
