如果在iTunes上以编程方式设置Itunes：Keep iTunes Folder Organized，我该怎么办？

Question

如果Itunes：首选项：高级：保持iTunes文件夹组织是如何在Windows上以编程方式设置的，我的Java应用程序与iTunes交互需要知道这一点。

不幸的是，iTunes xml文件或Itunes COM API似乎都没有提供这些信息，我认为它是因为它们是存储在其他地方的偏好但我怎么能知道是否启用了，我还需要知道这是为了将文件复制到iTunes Media添加到库时的文件夹

更新：注册表中没有任何内容，但我找到了一个首选项文件

C：\\ Users \\ username \\ AppData \\ Roaming \\ Apple Computer \\ iTunes

但它似乎是加密/编码，我不知道如何读取值

更新2：

保存了一份文件，在添加到库时将复制文件的值更改为iTunes Media Folder并进行了比较并获得了更改

<key>Documents:132</key>

但是你可以看到很难发现差异，并且我担心如果我攻击这个valkue它可能会在iTunes版本之间中断，有没有办法解码这个文件？

我发现Apache Commons Configuration支持Apples plist格式为Xml格式http://commons.apache.org/proper/commons-configuration/apidocs/org/apache/commons/configuration/plist/XMLPropertyListConfiguration.html但不幸的是二进制格式在这里使用

我写了这个列出所有键的代码，然后尝试解码位置属性，因为我知道这只包含一个base64编码器文件路径。

public File getITunesXMLFile()
    {
        String homedir = System.getProperty("user.home");

        File prefsFile = new File(homedir,"AppData/Roaming/Apple Computer/iTunes/iTunesPrefs.xml");
        try
        {
            XMLPropertyListConfiguration xpc = new XMLPropertyListConfiguration(prefsFile);
            xpc.load();
            Iterator<String> keys = xpc.getKeys();
            while(keys.hasNext())
            {
                String nextKey = keys.next();
                System.out.println(nextKey+":"+xpc.getProperty(nextKey).getClass());
            }
            ArrayList location = (ArrayList)xpc.getProperty("User Preferences.iTunes Library XML Location:1");
            System.out.println("Location:"+location.get(0).getClass());
            System.out.println("Location:"+location.get(1).getClass());

            System.out.println("Location1:"+ new BASE64Decoder().decodeBuffer(location.get(0).toString()));
            System.out.println("Location2:"+ new BASE64Decoder().decodeBuffer(location.get(1).toString()));
        }
        catch(Exception ex)
        {
            MainWindow.logger.log(Level.SEVERE,"Unable to open iTunes Prefs file:"+prefsFile.getName(),ex);
        }
        File xmlFile = new File(homedir + "/Music/iTunes/iTunes Music Library.xml");
        if (!xmlFile.exists())
        {
            return null;
        }
        return xmlFile;
    }

但遗憾的是没有工作，因为数据作为类型[B类的ArrayList]返回，这对我来说没有意义，它不是类的有效名称。

输出是

找到一个已经支持二进制code.google.com/p/plist的图书馆看起来很有希望

我已设法使用此库来解码Xml文件位置，如下所示（来自Apache Commons Codec 1.8的Base64类）

public File getITunesXMLFile()
    {
        System.getProperties().list(System.out);
        String homedir = System.getProperty("user.home");
        File prefsFile = new File(homedir,"AppData/Roaming/Apple Computer/iTunes/iTunesPrefs.xml");
        File xmlFile;
        try
        {
            NSDictionary rootDict = (NSDictionary) PropertyListParser.parse(prefsFile);
            NSDictionary userPrefs = (NSDictionary) rootDict.objectForKey("User Preferences");
            if(userPrefs!=null)
            {
                NSData iTunesLocation = (NSData) userPrefs.objectForKey("iTunes Library XML Location:1");
                if(iTunesLocation!=null)
                {
                    String base64 = iTunesLocation.getBase64EncodedData();
                    String filepath = new String(Base64.decodeBase64(base64),"UTF-16LE");
                    xmlFile = new File(filepath);
                    System.out.println(filepath+":File Exists:"+xmlFile.exists());
                    if (xmlFile.exists())
                    {
                        return xmlFile;
                    }
                }
            }
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
            //Use default then
            xmlFile = new File(homedir + "/Music/iTunes/iTunes Music Library.xml");
            if (xmlFile.exists())
            {
                return xmlFile;
            }
        }
        return null;
    }

我试图对我真正感兴趣的数据执行此操作，我能够从Documents：132键中提取base64encoded数据，但不幸的是尝试解码这个base64encoding并没有真正让我在任何地方，也许我只需要看看对于启用/禁用标志时base64encoded数据的差异。

 public boolean isiTunesCopyFolderToMediaFolder()
    {
        String homedir = System.getProperty("user.home");
        File prefsFile = new File(homedir,"AppData/Roaming/Apple Computer/iTunes/iTunesPrefs.xml");
        try
        {
            NSDictionary rootDict = (NSDictionary) PropertyListParser.parse(prefsFile);
            NSDictionary userPrefs = (NSDictionary) rootDict.objectForKey("User Preferences");
            if(userPrefs!=null)
            {
                NSData options = (NSData) userPrefs.objectForKey("Documents:132");
                if(options!=null)
                {
                    String base64 = options.getBase64EncodedData();
                    System.out.println("optionBase54Data:"+base64);
                    String optionData = new String(Base64.decodeBase64(base64));
                    System.out.println("optionData:"+optionData);
                    return true;
                }
            }
        }
        catch(Exception ex)
        {
            ex.printStackTrace();
        }
        return false;
    }

Answer 1

我使用设置打开和关闭复制了iTunesPrefs.xml，然后比较了差异。

检查（真）

Base64编码：AAIAAAAAAAEAAAAGAQAA ///// wEAAHoAAP //// 8EAEYAbABhAHQAAAAAAAAAA

十六进制值：02 01 06 01 01 7a 04 46 6c 61 74

没有检查（假）

Base64编码：AAIAAAAAAAEAAAAGAQAA ///// wEAAHsAAP //// 8EAEYAbABhAHQAAAAAAAAAA

十六进制值：02 01 06 01 01 7b 04 46 6c 61 74

这包含在首选项：130中，这些值是如何存储的我不知道，也许你可以在这里找到一些东西。 考虑使用命令行查找文件中的diff ，使用diff for linux或fc for windows。

我知道这不是答案，但这不符合评论。
