有人知道如何在Chrome Packaged应用程序中获取 DirectoryEntry 对象的完整路径，无需任何折叠或其他快捷方式吗？
我在撰写谷歌浏览器打包应用程序。我的应用程序有一个按钮，用户可以使用 chrome.fileSystem API选择目录。当目录选择回到我的应用程序时，它由 DirectoryEntry 对象表示，该对象在 File API 。该对象在控制台中看起来像这样： $ $ $ $ $ c $ DirectoryEntry { filesystem：DOMFileSystem fullPath：/ to_read isDirectory：true isFile：false name：to_read __proto__：DirectoryEntry }
我使用的是Windows，目录的完整路径是 C：\ Users \David\Desktop\to_read
我想要一个函数那可以返回那条路径或其他东西。不幸的是，我发现的最接近的东西是 chrome.fileSystem.getDisplayPath ，但返回以下内容：
〜\Desktop\to_read来自 getDisplayPath 的返回值对于因为我想获得目录的全名（包括驱动器），所以我可以将它与其他完整目录路径进行比较。
我试过调用 toURL（）放在 DirectoryEntry 中，并返回一个空字符串。
关于我的项目：我想以Chrome Packaged App的身份编写iTunes资料库同步器。 iTunes资料库XML文件包含完整路径，如 file：// localhost / D：/David/Music/Bob/Bob%20Album/01%20Bob.mp3 。用户将给我的应用程序访问他的音乐文件夹，我希望能够告诉他是否允许我访问正确的文件夹。
这是目前（2014-01-10）不是Chrome的一个功能，但我已经建议它，他们正在努力：code.google/p/chromium/issues/detail?id = 322952
Does anyone know how to get the full path of a DirectoryEntry object in a Chrome Packaged App, without any tildes or other shortcuts?
I am writing a Google Chrome Packaged App. My app has a button where a user can choose a directory using chrome.fileSystem API. When the directory choice comes back to my app, it is represented by a DirectoryEntry object, which is defined in the File API. The object looks like this in the console:
DirectoryEntry { filesystem: DOMFileSystem fullPath: "/to_read" isDirectory: true isFile: false name: "to_read" __proto__: DirectoryEntry }I am using Windows and the full path of the directory is
C:\Users\David\Desktop\to_readI would like a function that can return that path or something close. Unfortunately, the closest thing I found is chrome.fileSystem.getDisplayPath, but that returns the following:
~\Desktop\to_readThe return value from getDisplayPath is not useful to me, because I want to get the full name of the directory (including the drive) so I can compare it to some other full directory paths I have.
I tried calling toURL() on the DirectoryEntry and it returned an empty string.
A bit about my project: I want to write an iTunes library synchronizer as a Chrome Packaged App. The iTunes library XML file contains full paths like file://localhost/D:/David/Music/Bob/Bob%20Album/01%20Bob.mp3. The user will give my app access to his music folders, and I want to be able to tell if he gave me access to the right folders.
解决方案This is currently (2014-01-10) not a feature of Chrome, but I have suggested it and they are working on it:
