如何使用FacebookphpSDK3.0实现fql.multiquery

Question

我正在从2.xPHPSDK迁移到3.x。所有的多查询调用都中断了，我还没有弄清楚如何解决。

使用的facebook连接登录可以工作，并允许当前用户访问服务器端的数据。我假设这验证了我的访问令牌是合法的。

我尝试了以下代码变体，每次都会得到错误：

老路：

        $id = $fb->getUser(); // RETURNS A VALID USER ID
        $fql = '{ "friends" : "SELECT uid FROM user WHERE has_added_app=1 and uid IN (SELECT uid2 FROM friend WHERE uid1 = '.$id.')", "profiles" : "SELECT uid, name, pic_square FROM user WHERE uid IN (SELECT uid FROM #friends)"}';

        $response = $fb->api( array('method' => 'fql.multiquery','queries' => $fql));

提供错误: PHP致命错误:未捕获异常: 102:要求用户会话\n抛出

采用了新的方法：

        $id = $fb->getUser(); // RETURNS A VALID USER ID
        $fql = '{ "friends" : "SELECT uid FROM user WHERE has_added_app=1 and uid IN (SELECT uid2 FROM friend WHERE uid1 = '.$id.')", "profiles" : "SELECT uid, name, pic_square FROM user WHERE uid IN (SELECT uid FROM #friends)"}';

        $response = $fb->api( array('method' => 'fql.query','query' => $fql));

给出错误: PHP致命错误:未察觉的异常: 601:解析器错误:在0位置意外的“{”

任何了解如何使用新的PHP进行多查询的帮助都将不胜感激。

Answer 1

对于特定的查询，只在一个查询中使用新的 fql Graph端点：

$user = $facebook->getUser();
if ($user) {
  try {
    $fql = urlencode("SELECT uid, name, pic_square FROM user WHERE is_app_user = 1 AND uid IN (SELECT uid2 FROM friend WHERE uid1 = $user)");
    $response = $facebook->api("/fql?q={$fql}");
  } catch (FacebookApiException $e) {
    echo '<pre>'.htmlspecialchars(print_r($e, true)).'</pre>';
    $user = null;
  }
}

还可以使用is_app_user而不是不推荐的has_added_app 1！

只需将查询作为关联数组传递：

  $common_fields_fql = 'SELECT uid, email, contact_email, first_name, last_name, birthday_date, pic_square, sex, hometown_location, current_location, is_app_user FROM user WHERE uid ';
  $fql = array(
    'friends' => 'SELECT uid2 FROM friend WHERE uid1 = me()',
    'friends_details' => $common_fields_fql . 'IN (SELECT uid2 FROM #friends)',
    'me' => $common_fields_fql . '= me()',
    'family' => 'SELECT uid, birthday, name, relationship FROM family WHERE profile_id = me()',
  );
  $details = $facebook->api(array(
    'method'   => 'fql.multiquery',
    'queries'  => $fql,
  ));
