如何使用 facebook php sdk 3.0 执行 fql.multiquery答案

【问题描述】：

我正在从 2.x PHP SDK 迁移到 3.x。所有的多查询调用都被破坏了，我无法弄清楚如何解决。

使用 oauth javascript 的 facebook 连接登录可以工作，并允许在服务器端访问当前用户的数据。我假设这可以验证我的访问令牌是合法的。

我尝试了以下代码变体，但每次都会出错：

老办法：

        $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.multiquery','queries' => $fql));

给出错误：PHP 致命错误：未捕获异常：102：需要用户会话\n 抛出

假设的新方法：

        $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：未捕获异常：601：解析器错误：位置 0 处出现意外“{”

感谢任何帮助了解如何使用新的 PHP SDK 进行多查询。

【解决方案1】：

对于您的特定查询，请使用new fql Graph API 端点并且仅在一个查询中：

$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;
  }
}

同时使用is_app_user 代替已弃用的has_added_app！

【解决方案2】：

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,
  ));
