我如何才能將我的應用程序的manage_pages權限設置爲僅限特定頁面。現在我的應用程序獲得管理fb用戶的所有頁面的權限..我如何限制此功能並僅獲得訪問特定頁面的權限?如何將manage_pages權限設置爲特定的Facebook頁面?
我正在使用一種簡單的身份驗證方法。
$app_id = 'xxxxxxxxxxxxx';
$app_secret = 'xxxxxxxxxxxxxxxx';
$my_url = 'http://xxxxxxxxxxx.com/xxxx/facebook?client=params';
$code = $_REQUEST["code"];
//auth user
if(empty($code)) {
$dialog_url = 'https://www.facebook.com/dialog/oauth?client_id='
. $app_id . '&redirect_uri=' . urlencode($my_url).'&scope=offline_access,read_stream,publish_stream,manage_pages';
echo("<script>top.location.href='" . $dialog_url . "'</script>");
}
//get user access_token
$token_url = 'https://graph.facebook.com/oauth/access_token?client_id='
. $app_id . '&redirect_uri=' . urlencode($my_url)
. '&client_secret=' . $app_secret
. '&code=' . $code;
$access_token = file_get_contents($token_url);
am using the above code for authentication. when i try to print the $_REQUEST params, i couldnt find any variable names 'signed_request'. is any other method can we use with the above code..??
