Facebook api搜索。

我是學習Facebook API搜索的新手。我使用這段代碼，但是resault是空的。誰能幫我？謝謝。Facebook api搜索。

<form action ="index.php" method ="post"> 
<input type="text" value="what is?" name="search" style="color:#999;text-align:center;" onfocus="if (value =='what is?'){value =''}" onblur="if (value ==''){value='what is?'}"/> 
<input type ="submit" value="ok" /> 
</form> 
<?php 
function callFb($url) 
{ 
    $ch = curl_init(); 
    curl_setopt_array($ch, array(
     CURLOPT_URL => $url, 
     CURLOPT_RETURNTRANSFER => true 
    )); 

    $result = curl_exec($ch); 
    curl_close($ch); 
    return $result; 
} 

$url = "https://graph.facebook.com/oauth/access_token?client_id=api_id&redirect_uri=my_url&client_secret=my_secret"; 
$access_token = callFb($url); 
$access_token = substr($access_token, strpos($access_token, "=")+1, strlen($access_token)); 

$url1 = "https://graph.facebook.com/search?access_token=".$access_token."&q=".urlencode($_POST['search'])."&type=user"; 
$ret_json = callFb($url1); 
$users = json_decode($ret_json, true); 

?> 

<img src="https://graph.facebook.com/<? echo $users[data][0][id]; ?>/picture?type=small">

'https：//graph.facebook.com/oauth/access_token？client_id = api_id＆redirect_uri = my_url＆client_secret = my_secret' 您需要首先用適當的數據替換'api_id'，'my_url'和'my_secret' – 2010-12-20 14:28:08

@Horia Dragomir，yes ，我已經取代了我的，但結果是空的，即使我搜索我自己的名字。 – 2010-12-20 14:48:53

'$ access_token'是否意味着有效？ – ajreal 2010-12-20 14:59:39

你的$ url參數設置爲：

「https://graph.facebook.com/oauth/access_token?ient_id=api_id & REDIRECT_URI = my_url & client_secret = my_secret」;

'client_id'，'redirect_uri'和'client_secret'的值仍設置爲佔位符。處理這種情況最好的辦法是，像這樣：

<? 

// params to be encoded in the auth URL 
$params = array(
    'client_id' => $fb_app_id, 
    'redirect_uri' => $my_redirect_url, 
    'client_secret' => $fb_app_secret, 
); 

// encode the params in to a string 
$paramString = "?"; 
foreach($params as $key=>$value) { 
    $paramString .= "&{$key]=" . urlencode($value); 
} 

// auth URL 
$url = "https://graph.facebook.com/oauth/access_token" . $paramString;

你應該分配真正需要的值$fb_app_id，$my_redirect_url，和$ fb_app_secret。

對於$fb_app_id和$fb_app_secret，您可以從您應用的相關應用（位於http://www.facebook.com/developer）的Facebook Developer區域的設置中獲取它們。

的$my_redirect_url的值必須是「網站」的編輯APP區域選項卡內的真實網址：http://drktd.com/3zc4

確保你不傳遞任何作爲零或零

嘗試這與您訪問令牌在瀏覽器

https://graph.facebook.com/search?q=mark&type=user&access_token=<%=your token%>

您將得到以下響應

    "data": [ 
     { 
     "name": "Mark Maglasang", 
     "id": "142137849672813" 
     }, 
     { 
     "name": "Mark Daniel", 
     "id": "137983696724314"
