确定swf是否处于“调试”播放器或模式 [英] Determine if swf is in a "debug" player or mode

问题描述

有没有办法使用Flash（CS3 + AS3）来确定发布的swf是否在调试播放器或Flash的调试模式下运行？

Is there a way using Flash (CS3+AS3) to determine if the published swf is running in a debug player or in Flash's debug mode?

我是意识到Flex提供了设置不同的构建目标（释放/调试）的功能，您可以使用 CONFIG :: debug 为 #ifdef 在编译时包含代码的样式。

I'm aware that Flex provides the ability to setup different build targets (release/debug) and that you can use something like CONFIG::debug for #ifdef style inclusion of code at compile time.

我想象的是像$ code> System.isDebug（）但找不到任何东西。我想使用这个，因为我的应用程序中有调试功能，我确定不希望在生产环境中可用。

I'm imagining something like System.isDebug() but can't find anything. I want to use this because there's debug functionality in my app that I definitely don't want to be available in a production environment.

推荐答案

查看这个课程 http://blog.another-d-mention.ro/programming/how-to-identify-at-runtime-if-swf-is -in-debug-or-release-mode-build /

这个类提供了两个相关的（和不同的）信息：

This class provides two pertinent (and different) pieces of information:

• SWF是否使用-debug开关构建（已调试符号）？


• Flash Player是否为调试播放器（有能力显示错误等）？

Capabilities.isDebugger只回答第二个问题 - 用户是否正在运行Flash调试播放器。在您的情况下，要在调试版本上部署应用程序，您需要--debug构建检查（然后不要将-debug版本生成）生产。

The Capabilities.isDebugger only answers the second question - is the user running the Flash Debug player. In your case, to gate portions of your application on a debug build, you want the -debug build check (and then don't deliver -debug builds into production).

但请注意，这两个检查都是运行时检查。在调试代码周围使用条件编译（又称CONFIG :: debug）仍然是一个好主意，因为它将确保可能敏感的调试代码不会在最终的SWF中提供，使其尽可能小且安全。

Note however, that both these checks are runtime checks. Using conditional compilation (aka CONFIG::debug) around your debug code is still a good idea, as it will ensure that possibly sensitive debug code is NOT delivered in the final SWF, making it as small and secure as possible.

我在这里复制引用的代码，以防博客链接发生故障：

I'm reproducing the referenced code here, in case the blog link ever goes down:

package org.adm.runtime
{
  import flash.system.Capabilities;

  public class ModeCheck
  {
    /**
     * Returns true if the user is running the app on a Debug Flash Player.
     * Uses the Capabilities class
     **/
    public static function isDebugPlayer() : Boolean
    {
        return Capabilities.isDebugger;
    }

    /**
     * Returns true if the swf is built in debug mode
     **/
    public static function isDebugBuild() : Boolean
    {
        var stackTrace:String = new Error().getStackTrace();
        return (stackTrace && stackTrace.search(/:[0-9]+]$/m) > -1);
    }

    /**
     * Returns true if the swf is built in release mode
     **/
    public static function isReleaseBuild() : Boolean
    {
        return !isDebugBuild();
    }
  }
}
