查找应用名称

Question

FlashBuilder 弹性

在我的重启代码中，我有以下行：

var file:File = File.applicationDirectory.resolvePath("app:/playerAir.exe");

只要应用名称不变，它就可以工作

我想要一种自动查找此应用名称的方法来更改 "playerAir"。

原因： 如果我更改名称，我也必须在重启功能中更改它 如果客户端有多个版本的文件（playerAir.exe、playerAir1.exe、playerAir2.exe），那么它会启动错误的版本。

我怎样才能使它根据应用程序的名称进行相应的更改？

reboot函数代码如下：

public function Reboot():void                                                                   ///

            var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();     ///
            var app:WindowedApplication=WindowedApplication(FlexGlobals.topLevelApplication);           ///
            var swf:String=stage.loaderInfo.url.substring(0,stage.loaderInfo.url.lastIndexOf("/")+1);   ///get swf's path (- *name*.swf)
            swf=swf+app.applicationID;                                                                  ///adds applicationID after the path. ex: app:/ -> becomes -> app:/m7tvPlayerAir

您应该能够使用舞台的loaderinfo 对象的url 属性来确定应用程序名称。

这将指向正在运行的 swf 文件，默认情况下与可执行文件同名。

因此，如果您知道您的应用具有 .exe 扩展名，这可能会起作用：

var path:String = stage.loaderInfo.url.replace(".swf",".exe");
var file:File = File.applicationDirectory.resolvePath(path);

---

如果您正在运行一个多平台应用程序，您可以在应用程序目录中查找合适的应用程序扩展：

//get the swf path minus the 'swf'
var swf:String = stage.loaderInfo.url.substring(0,stage.loaderInfo.url.lastIndexOf(".") + 1);

//get all the files in the application directory
var d = File.applicationDirectory.getDirectoryListing();

//find your executable (this is just a sample of how to do this, ideally you'd have a compile time constant to indicate the extension of your current build)
var exe:String;
for each(var f:File in d){
    if(f.url.indexOf(swf) === 0 && (f.url.indexOf(".dmg") > -1 || f.url.indexOf(".app") > -1 || f.url.indexOf(".exe") > -1)){
        exe = f.url; //found the executable path
        break; //stop the loop
    }
}
