怎么了?少了什么?哪些fbs cookie未创建

您使用的是旧的oauth 1.0格式。你现在必须使用新的格式

PHP代码中的一个示例,应该足够接近,可以修改为js,只需很少的更改:

函数get_facebook_cookie() { $CI=&get_instance(); $app_id=$CI->config->item('facebook_app_id'); $application\u secret=$CI->config->item('facebook\u app\u secret'); 如果(isset($COOKIE['fbsr.$app_id])){ 列表($encoded_sig,$payload)=分解('.',$COOKIE['fbsr'.$app_id],2)

}


这是从这里传来的,还有一些关于这个问题的小道消息。

嗯……你在那里发布的其他错误呢?你的浏览器允许该网站在你的电脑上创建cookie吗?
     $sig = base64_decode(strtr($encoded_sig, '-_', '+/'));
     $data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);

     if (strtoupper($data['algorithm']) !== 'HMAC-SHA256') {
         return null;
     }
     $expected_sig = hash_hmac('sha256', $payload,
     $application_secret, $raw = true);
      if ($sig !== $expected_sig) {
          return null;
      }
      $token_url = "https://graph.facebook.com/oauth/access_token?"
     . "client_id=" . $app_id . "&client_secret=" . $application_secret. "&redirect_uri=" . "&code=" . $data['code'];
      $response = file_get_contents($token_url);

      $params = null;
      parse_str($response, $params);
      $data['access_token'] = $params['access_token'];
      return $data;
  }else{
      return null;
 }
