Facebook连接'下一个'错误

Mar*_*ark 9 javascript php facebook

我正在尝试使用新的facebook身份验证系统,但我无法让登录工作.

我收到以下错误消息:

API错误代码:100

API错误说明:参数无效

错误消息:next不归应用程序所有.

发送到Facebook的网址是:

http://www.facebook.com/connect/uiserver.php?app_id=444444444444444&next=http%3A%2F%2Fstatic.ak.fbcdn.net%2Fconnect%2Fxd_proxy.php%23%3F%3D%26cb%3Df357eceb0361a8a% 26origin%3Dhttp%253A%252F%252Fwww.mysite.com%252Ff38fea4f9ea573%26relation%3Dopener%26transport%3Dpostmessage%26frame%3Df23b800f8a78%26result%3DxxRESULTTOKENxx&显示弹出=&信道= HTTP%3A%2F%2Fwww.mysite.com%2Ffbtester.php&取消= HTTP%3A%2F%2Fstatic.ak.fbcdn.net%2Fconnect%2Fxd_proxy.php%23%3F%3D%26CB%3Df6095a98598be8%26origin%3Dhttp%253A%252F%252Fwww.mysite.com%252Ff38fea4f9ea573%26relation%3Dopener% 26transport%3Dpostmessage%26frame%3Df23b800f8a78%26result%3DxxRESULTTOKENxx&语言环境= EN_US&return_session = 1&session_version = 3&fbconnect = 1&帆布= 0&legacy_return = 1&方法= permissions.request

请注意,网址中的"下一个"变量是:

下一个HTTP =%3A%2F%2Fstatic.ak.fbcdn.net%2Fconnect%2Fxd_proxy.php%23%3F%3D%26CB%3Df357eceb0361a8a%26origin%3Dhttp%253A%252F%252Fwww.mysite.com%252Ff38fea4f9ea573%26relation% 3Dopener%26transport%3Dpostmessage%26frame%3Df23b800f8a78%26result%3DxxRESULTTOKENxx

什么想法可能会出错？我所做的就是从facebook的网站上复制并粘贴facebook登录演示代码:

 <?php
define('FACEBOOK_APP_ID', 'your application id');
define('FACEBOOK_SECRET', 'your application secret');

function get_facebook_cookie($app_id, $application_secret) {
  $args = array();
  parse_str(trim($_COOKIE['fbs_' . $app_id], '\\"'), $args);
  ksort($args);
  $payload = '';
  foreach ($args as $key => $value) {
    if ($key != 'sig') {
      $payload .= $key . '=' . $value;
    }
  }
  if (md5($payload . $application_secret) != $args['sig']) {
    return null;
  }
  return $args;
}

$cookie = get_facebook_cookie(FACEBOOK_APP_ID, FACEBOOK_SECRET);

?>

               cookie: true, xfbml: true});
      FB.Event.subscribe('auth.login', function(response) {
        window.location.reload();
      });
    </script>
  </body>

我得到了同样的错误,但我使用的是Rails,问题是Connect URL没有更新.我的本地应用程序在端口3000上运行,Connect URL指向端口80.

看看改变是否适合你.

转到http://www.facebook.com/developers
编辑您正在处理的应用程序
单击Connect左侧的选项卡
验证是否Connect URL正确设置

我对 Facebook API 不太了解，但我确实知道您必须实际替换文本your application idandyour application secret为您的应用程序 ID 和应用程序密钥。:)
