我想订阅picture
特定 Facebook 页面的对象。为了做到这一点,我正在关注这篇文章。我在这里上传了用作回调的 PHP 文件。下面的代码:
<?php
/**
* This is sample subscription endpoint for using Facebook real-time update
* See http://developers.facebook.com/docs/api/realtime to additional
* documentation
*/
// Please make sure to REPLACE the value of VERIFY_TOKEN 'abc' with
// your own secret string. This is the value to pass to Facebook
// when add/modify this subscription.
define('VERIFY_TOKEN', 'app_code_123');
$method = $_SERVER['REQUEST_METHOD'];
// In PHP, dots and spaces in query parameter names are converted to
// underscores automatically. So we need to check "hub_mode" instead
// of "hub.mode".
if ($method == 'GET' && $_GET['hub_mode'] == 'subscribe' &&
$_GET['hub_verify_token'] == VERIFY_TOKEN) {
echo $_GET['hub_challenge'];
} else if ($method == 'POST') {
$updates = json_decode(file_get_contents("php://input"), true);
// Replace with your own code here to handle the update
// Note the request must complete within 15 seconds.
// Otherwise Facebook server will consider it a timeout and
// resend the push notification again.
error_log('updates = ' . print_r($updates, true));
}
?>
然后我access_token
按照文章中的指示得到了我的应用程序详细信息中的client_id
替换APP_ID
和client_secret
替换APP SECRET
:
https://graph.facebook.com/oauth/access_token?grant_type=client_credentials&client_id=<REMOVED APP ID>&client_secret=<REMOVED CLIENT SECRET>
随后尝试创建订阅:
https://graph.facebook.com/<REMOVED APP ID>/subscriptions?access_token=<REMOVED APP ACCESS TOKEN>object=user&fields=feed&verify_token=app_code_123&method=post&callback_url=http://www.shameemcompany.com/facebook.php
但它失败并出现错误:
"message": "(#2200) callback verification failed: ",
"type": "OAuthException",
"code": 2200
我想订阅特定的 Facebook 页面,那么我将在哪里或如何指定它?
