基於facebook instructions (Scenario 4)我使用以下網址Facebook的訪問令牌過期

https://graph.facebook.com/oauth/access_token?client_id=APP_ID&client_secret=CLIENT_SECRET& grant_type=fb_exchange_token&fb_exchange_token=OLD_ACCESS_TOKEN 

,以獲得新的訪問令牌,但我得到如下:

{「錯誤」:{ 「消息「:」驗證訪問令牌的錯誤:會話在unix時間已過期1365257820.當前unix時間爲1365759029.「, 」type「:」OAuthException「, 」code「:190, 」error_subcode「:463}}

不起作用。任何幫助讚賞。

編輯:明白了!工作原理是這樣

如果訪問令牌到期必須將其存儲在服務器上之後,瀏覽器

<?php 
    $app_id = "your app id"; 
    $app_secret = "your app secret"; 
    $my_url = "http://apps.facebook.com/your_app_name"; 

    // known valid access token stored in a database 
    $access_token = "your old access token"; 

    $code = $_REQUEST["code"]; 

    // If we get a code, it means that we have re-authed the user 
    //and can get a valid access_token. 
    if (isset($code)) { 
    $token_url="https://graph.facebook.com/oauth/access_token?client_id=" 
     . $app_id . "&redirect_uri=" . urlencode($my_url) 
     . "&client_secret=" . $app_secret 
     . "&code=" . $code . "&display=popup"; 
    $response = file_get_contents($token_url); 
    $params = null; 
    parse_str($response, $params); 
    $access_token = $params['access_token']; 
    } 


    // Attempt to query the graph: 
    $graph_url = "https://graph.facebook.com/me?" 
    . "access_token=" . $access_token; 
    $response = curl_get_file_contents($graph_url); 
    $decoded_response = json_decode($response); 

    //Check for errors 
    if ($decoded_response->error) { 
    // check to see if this is an oAuth error: 
    if ($decoded_response->error->type== "OAuthException") { 
     // Retrieving a valid access token. 
     $dialog_url= "https://www.facebook.com/dialog/oauth?" 
     . "client_id=" . $app_id 
     . "&redirect_uri=" . urlencode($my_url); 
     echo("<script> top.location.href='" . $dialog_url 
     . "'</script>"); 
    } 
    else { 
     echo "other error has happened"; 
    } 
    } 
    else { 
    // success 
    echo("success" . $decoded_response->name); 
    echo($access_token); 
    } 

    // note this wrapper function exists in order to circumvent PHP’s 
    //strict obeying of HTTP error codes. In this case, Facebook 
    //returns error code 400 which PHP obeys and wipes out 
    //the response. 
    function curl_get_file_contents($URL) { 
    $c = curl_init(); 
    curl_setopt($c, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($c, CURLOPT_URL, $URL); 
    $contents = curl_exec($c); 
    $err = curl_getinfo($c,CURLINFO_HTTP_CODE); 
    curl_close($c); 
    if ($contents) return $contents; 
    else return FALSE; 
    } 
?> 

上面的腳本會給你像下面的一個瀏覽器上的URL首先運行下面的PHP腳本

https://graph.facebook.com/oauth/access_token?code= ...

然後得到的字符串(應該是這樣的:AQCn41Svv5DbWrnFY0Wf ..... YbNm_yz2rE#_) 碼=和粘貼的代碼URL =下方運行下面的網址上的瀏覽器

https://graph.facebook.com/oauth/access_token?client_id=App_Id&redirect_uri=http://apps.facebook.com/poemsoflove&client_secret=App_Secret&code=AQCn41Svv5DbWrnFY0Wf.....YbNm_yz2rE#_&display=popup

,你會得到下面的響應是60天

access_token=<Extended_Access_Token>&expires=5180130 

複製一個新的訪問令牌並粘貼後的字符串access_token =到您的服務器上的腳本,在您的頁面上發佈新帖子

這意味着你的舊訪問令牌已過期。你可以用一個新的短期訪問令牌重試同樣的事情 –

謝謝我用新的短期訪問令牌做了它 – stefanosn

你剛剛寫訪問令牌給世界,請注意它。任何人都可以濫用它。 –

  1. 創建應用程序Facebook Developer Page

用PHP後可以得到實時訪問托克

$app_id = '{Application Id}'; 
$app_secret = '{Application Secret}'; 
$access_token = "https://graph.facebook.com/oauth/access_token?client_id=$app_id&client_secret=$app_secret&grant_type=client_credentials"; 
$access_token = file_get_contents($access_token); // returns 'accesstoken=APP_TOKEN|APP_SECRET' 
$access_token = str_replace('access_token=', '', $access_token); 
0
$app_id = 'APP_ID'; 
$app_secret = 'APP_SECRET'; 
$access_token_url = "https://graph.facebook.com/oauth/access_token?client_id=$app_id&client_secret=$app_secret&grant_type=client_credentials"; 
$access_token_data = file_get_contents($access_token_url); 
$access_token_arr = json_decode($access_token_data); 
$access_token = $access_token_arr->access_token;

請不要只是發佈一些代碼作爲答案。請解釋你的邏輯。 –
