反正是有在Flex应用程序找出（在运行时），当运行的SWF编译？

Is there anyway in a flex application to figure out (in runtime) when the running swf was compiled?

我想在服务器上的SWF的最新文件版本比较这并检测是否有在服务器上较新的版本，如果是强制用户重新加载他们的浏览器来获得新的版本。

I'd like to compare this with the latest file version of the swf on the server and detect if there's a newer version on the server and if so force the user to reload their browser to get the new version.

我需要这也与从缓存主权财富基金的工作。

I need this to also work with swfs from the cache.

推荐答案

我常做，以确保用户获得一个Flash文件的最新版本（因为有一些奇怪的与Flash内容的缓存）是使用一个服务器端脚本附加文件被修改的时间。

What I normally do to make sure the user gets the latest version of a Flash file (because there is something weird with the caching of Flash content) is to use a serverside script to append the time the file was changed.

我也一直在尝试用在SWF设置变量，尽管这需要一些命令行欺骗，如果你不使用一个构建脚本不会真正成为现实。

I've also been experimenting with setting variables in the swf, although that requires some command line trickery and won't really be practical if you're not using a build script.

基本上你添加到您mxmlc的电话：

Basically you append this to your mxmlc call:

-define+=BUILD::DATE,"2008-12-10"

那么变量BUILD ::日期将提供您的构建过程中，所以你可以用它来设置上，你以后要阅读静态变量：

Then the variable BUILD::DATE will be available during your build, so you can use that to set at static variable which you later read:

private static var COMPILEDATE:String = DATE;
