如何使用PHP SDK製作fql multyquery

Question

我正在嘗試使用PHP SDK製作fql multy查詢。這是我的代碼

try { 
    $fql = array( 
     "query1" => "SELECT uid2 FROM friend WHERE uid1 = me()", 
     "query2" => "SELECT name, url, pic FROM profile WHERE id IN (SELECT uid2 FROM #query1)" 
    ); 
    //$fql = "SELECT uid2 FROM friend WHERE uid1 = me()"; 
    // Proceed knowing you have a logged in user who's authenticated. 
    $user_profile = $facebook->api(array(
     'method' => 'fql.multiquery', 
     'query' => $fql, 
    )); 
} catch (FacebookApiException $e) { 
    error_log(print_r($e->getMessage(), true)); 
    $user = NULL; 
} 

而這總是會返回一個不帶消息

[04月 - 2012 20時22分26秒UTC] PHP公告：未定義的屬性： FacebookApiException :: $ getMessage in C：\ Program Files （x86）\ Zend \ Apache2 \ htdocs \ wordpress \ wp-content \ plugins \ all-in-one-event-calendar \ lib \ plugins \ A1ecFacebookConnectorPlugin.php on line 120 [04- May-2012 20:22:26 UTC]

我明顯做錯了什麼，可能是什麼？

好吧，我發現如何做到這一點，你必須使用queries作爲參數，而不是query

try { 
    $fql = array( 
     "query1" => "SELECT uid2 FROM friend WHERE uid1 = me()", 
     "query2" => "SELECT name, url, pic FROM profile WHERE id IN (SELECT uid2 FROM #query1)" 
    ); 
    //$fql = "SELECT uid2 FROM friend WHERE uid1 = me()"; 
    // Proceed knowing you have a logged in user who's authenticated. 
    $user_profile = $facebook->api(array(
     'method' => 'fql.multiquery', 
     'queries' => $fql, 
    )); 
} catch (FacebookApiException $e) { 
    error_log(print_r($e->getMessage(), true)); 
    $user = NULL; 
}

您的問題是您正在嘗試撥打$e->getMessage哪些不存在。你對線120碼應爲：

error_log(print_r($e, true)); 

如果您有與multiquery問題，你可以做到這一點作爲一個單一的查詢：

$fql = "SELECT name, url, pic FROM profile WHERE id IN 
     (SELECT uid2 FROM friend WHERE uid1 = me())"; 

$user_profile = $facebook->api(array(
    'method' => 'fql.query', 
    'query' => $fql, 
)); 

我已經能夠得到的查詢運行像這三個選擇很深。四個SELECT似乎太多了。
