Question

我正在Flash Builder（Flex）中开发AIR应用程序，我需要选项与计算机上的串行端口进行通信。所以我正在使用Serproxy来帮助我。

我希望能够在我的应用程序运行时启动serproxy.exe。我尝试了两种方法，但它们都不适合我。

我已使用extendedDesktop设置supportedProfiles。

第一种方法：

var file:File = File.applicationDirectory.resolvePath("assets/serproxy.exe");
file.openWithDefaultApplication();

这会打开程序，但会立即关闭它。没有错误。

第二种方法：

var file:File = File.applicationDirectory.resolvePath("assets/serproxy.exe");

var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
var process:NativeProcess = new NativeProcess();

process.start(nativeProcessStartupInfo);

虽然通过研究发现这种方法有效，但它对我没有任何作用。不会抛出任何错误，也不会启动任何程序。

如果有任何想法请告诉我！感谢

Answer 1

我已经解决了。我的问题是，由于Serproxy使用cmd.exe打开，因此在保持文件打开时存在一些问题，因为Windows喜欢自动关闭它。我通过创建文件的快捷方式并使用

预先挂起其目标来解决这个问题

C:\Windows\System32\cmd.exe /K "C:\...assets\serproxy.exe"

然后我可以用

运行快捷方式

var file:File = File.applicationDirectory.resolvePath("assets/serproxy.lnk");
file.openWithDefaultApplication();

窗户一直开着！

我去年写了一个名为 Disco Desktop 的应用程序，该应用程序使用TinkerProxy允许AIR通过USB串口与Arduino进行通信。我的TinkerProxy / TinkerProxyEvent类发布在下面。

应用程序捆绑了serproxy并使用Native Process API来调用它，因此有2个不同的安装程序 - Mac OS X和Windows。 TinkerProxy.as扩展了Socket，根据用户的输入在运行时写入serproxy配置文件，并基于此配置启动serproxy作为后台进程。终端/ cmd窗口永远不可见。注意：调用open（）而不是connect（）。包含在安装程序中的是Arduino的简单设备原理图和草图。

它可能不是我最好的代码，但确实有效。我希望它有所帮助。

使用URLRequest使用AIR

启动应用程序

public function clickButton():void{
var request : URLRequest = new URLRequest('C:\\path to serproxy\serproxy.exe');
navigateToURL(request)

also here are the paths to default folders
var appDir:File    = File.applicationDirectory;
var appStoreDir:File= File.applicationStorageDirectory;
var desktopDir:File = File.desktopDirectory;
var docDir:File    = File.documentsDirectory;
var userDir:File    = File.userDirectory;
var rootDirArr:Array = File.getRootDirectories();

使用Adobe AIR启动EXE（Serproxy）
