小编Bil*_*oes的帖子

在Google maps API v2中,我们国家的地图非常适合700x400px地图,其中包含以下内容:

map.getBoundsZoomLevel(<bounds of our country>)

但是在API v3中,该map.fitBounds()方法不适合在700x400的缩放级别 - 它缩小了一个级别.

这意味着map.fitBounds()计算带有一些"优雅边际"或其他东西.

我该如何影响这个保证金的大小？

我正在尝试按照此处的示例开发示例facebook php登录示例

我在这里托管了我的应用程序,但每当我尝试访问该链接时,我都会在问题中收到错误消息.这是抛出错误的代码段

try {
  $e = new FacebookApiException(array(// LINE 887
             'error_code' => curl_errno($ch),
             'error' => array(
             'message' => curl_error($ch),
             'type' => 'CurlException',
        ),
  ));
  curl_close($ch);
}

// edit suggested by Kneel-before ZOD
catch(FacebookApiException $e) {
  $result = $e->getResult();
  echo 'Got an : ', $e->getType(),' while posting';
  echo(json_encode($result));
}

catch(Exception $e){
  echo 'Caught exception: ',  $e->getMessage(), "\n";
}

我很确定我已经在index.php中正确设置了APP ID和密码.

这是我在Facebook上的应用程序设置的屏幕截图

任何帮助,将不胜感激.谢谢!

在浏览器中输入localhost:3000时出现上述错误.我试图重新启动浏览器,但这不起作用.

这是Rubymine中服务器控制台的堆栈跟踪:

看一下mySQL Dump,我遇到了一些东西,想知道它们是什么.

我知道了:

/*!50001 DROP TABLE IF EXISTS `xxx` */;

什么是50001旗帜,是否有他们的意思清单？
