css - 如何检查页面是否加载到 facebook canvas 中并相应地更改布局

Question

我正致力于创建 Flash 游戏网站，并希望制作它的 Facebook 应用程序版本。由于网站宽度大于 Canvas 默认宽度，我试图找到检查网站是否加载到 facebook Canvas 内并相应更改宽度的方法。请帮助我找到解决方案。

Answer 1

如果用户通过您的 Facebook canvas iframe 应用程序访问您的网站，对您服务器的请求将包含一个“signed_request”参数。您可以检查此参数以确定用户是否在 Facebook Canvas 内。

另请注意，如果您将 Canvas Width to Fluid 设置为:

You can set your Canvas Width to "Fixed (760px)", the default setting, which makes your app have a fixed width of 760 pixels. You can also set your width to "Fluid" which means that we set the iframe width to 100%. Your content will then be left-aligned and resize to fill the page as the user changes the width of their browser.
