Question

我正在尝试使用facebook积分，但我收到了这个错误：

“您使用的应用没有响应。请稍后再试。”

我不知道是什么原因，

我查看了firebug控制台，看到一些长时间的请求需要40秒，请求目标是： http：//0-if-w.channel.facebook.com/pull?channel=p_685255507& ; SEQ = 3及客户端ID = 25523dd1＆安培; CB = gcgh＆安培;空闲= 41＆安培;状态=活性

有没有人知道我做错了什么？

这是我的HTML代码：

Answer 1

//更改了回调页面的编码。如果您的回调页面是以UTF-8编码的，请检查它是否为没有BOM的UTF-8。

我认为这个主题解决了你的问题。希望能帮助到你： http://forum.developers.facebook.net/viewtopic.php?id=90781

Answer 2

这可能是因为

文件的最长执行时间少于
当您的服务器（callback url)未以正确的JSON格式发回响应时，会发生此错误。请确保这些格式的响应完全且一切正常
或您请求的服务器可能会遇到停机时间。

Answer 3

如果您使用来自Facebook Docs的callback.php示例，则注释掉26,32和第44行。

这将结束那种情况下的错误。

 // if ($item_id == '1a') {
    $item = array(
      'title' => '100 some game cash',
      'description' => 'Spend cash in some game.',
      // Price must be denominated in credits.
      'price' => 10,
      //'image_url' => 'http://some_image_url/coin.jpg',
    );

    // Construct response.
    $response = array(
                  'content' => array(
                                 0 => $item,
                               ),
                  'method' => $request_type,
                );
    // Response must be JSON encoded.
    $response = json_encode($response);
  //}

为什么会出现此错误：您使用的应用程序没有响应。请稍后再试
