PHP cURL：發佈到Facebook頁面爲頁面

Question

我嘗試了一個示例代碼發佈到Facebook頁面。但它發佈爲我自己。我已經包含Page_access_token。

授予的權限是'manage_pages'和'publish_action'。 這裏是我的代碼：

<?php 

    $page_id='xxxx'; 
    $page_access_token='cccc'; 
    $url="https://graph.facebook.com/{$page_id}/feed?message=Hello&access_token=".$page_access_token; 
    $ch=curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_POST, true); 
    curl_setopt($ch, CURLOPT_REFERER, ''); 
    curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate'); 
    curl_setopt($ch, CURLOPT_AUTOREFERER, true); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 10); 

    $value = json_decode(curl_exec($ch)); 
    $var_dump($value); 

?> 

我在哪裏出錯了？我如何解決它？ 我希望它作爲頁面發佈。由於

編輯： 我與/ $ PAGE_ID新的代碼字段=的access_token：

<?php 
    $page_id='xxx'; 
    $message='helloworld'; 
    $url="https://graph.facebook.com/v2.3/{$page_id}?fields=access_token"; 
    $curl = curl_init(); 
    curl_setopt($curl, CURLOPT_URL, $url); 
    curl_setopt($curl, CURLOPT_POST, true); 
    curl_setopt($curl, CURLOPT_REFERER, ''); 
    curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate'); 
    curl_setopt($curl, CURLOPT_AUTOREFERER, true); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($curl, CURLOPT_POSTFIELDS, $message); 
    curl_setopt($curl, CURLOPT_TIMEOUT, 10); 

    $json = json_decode(curl_exec($curl)); 
    var_dump($json); 
?> 

這將返回一個錯誤：

object(stdClass)#1 (1) { 
    ["error"]=> 
    object(stdClass)#2 (3) { 
    ["message"]=> 
    string(64) "(#210) A page access token is required to request this resource." 
    ["type"]=> 
    string(14) "OAuthException" 
    ["code"]=> 
    int(210) 
    } 
} 

我要去哪裏錯了？

我是否需要從圖形API瀏覽器創建page_access_token？或者上面的url足夠了？我該如何使用User_access_token來獲取page_access_token？

Answer 1

如果它發佈爲您自己，則表示您沒有使用Page Token。調試令牌，看看頁ID列 - that's你怎麼知道it'sa頁令牌：https://developers.facebook.com/tools/debug/

順便說一句，你應該使用新publish_pages留言的權限頁：https://developers.facebook.com/docs/apps/changelog#v2_3_changes

<?php 
    $page_id='xxx'; 
    $message='helloworld'; 
$access_token = "XXXXXXXXXXXXXXXXXXXXX"; 
    $url="https://graph.facebook.com/v2.3/{$page_id}/feed/?access_token=".access_token ."&message=".urlencode(message); 
    $curl = curl_init(); 
    curl_setopt($curl, CURLOPT_URL, $url); 
    curl_setopt($curl, CURLOPT_POST, true); 
    curl_setopt($curl, CURLOPT_REFERER, ''); 
    curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate'); 
    curl_setopt($curl, CURLOPT_AUTOREFERER, true); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($curl, CURLOPT_POSTFIELDS, $message); 
    curl_setopt($curl, CURLOPT_TIMEOUT, 10); 

    $json = json_decode(curl_exec($curl)); 
    var_dump($json); 
?>
