javascript - NWJS 应用程序在 Windows 上关闭后 Chrome 本地存储会被删除

Question

我有一个应用程序，它使用 Chrome 本地存储来保存用户电脑上的一些信息。

该应用程序在 OS X 和 Linux (Ubuntu) 上运行良好，但是在 Windows 8.1 上测试时，我打开了该应用程序的本地存储文件夹。有 2 个文件名为:

chrome-extension_nbcogalgoagjhkbkpjfkfcckdmochgmi_0.localstorage
chrome-extension_nbcogalgoagjhkbkpjfkfcckdmochgmi_0.localstorage-journal

关闭应用程序后，我在文件夹中看到两个文件都被删除了!

之后我再次打开应用程序，发现现在它创建了以下文件:

chrome-extension_cobbbbdapgeflbdpmchapmffabihofip_0.localstorage
chrome-extension_cobbbbdapgeflbdpmchapmffabihofip_0.localstorage-journal

关闭应用程序后，它们再次被删除。

我正在使用 NWJS SDK 13 alpha 版本 3，因为我们也在使用 Chrome Serial。

这是一个仅在 Windows 中发生的问题，尚未在其他版本的 Windows 上进行测试，但至少在 Windows 8.1 上是这样，当我检查 OS X 和 Ubuntu 上的本地存储文件夹时，文件没有被删除.

我正在管理员模式下执行它。

我还注意到关闭应用程序后它不会删除，而是再次打开它后。

不确定我应该发布哪些文件的代码，因此我将发布我认为可能有帮助的内容。我很少用 JS 编程，也没有用 NWJS 编程。可能我做错了什么，因为我不知道什么可能有用或什么没有，我对制作 MCVE 没有信心......

今天在 Google 群组发布了 NWJS 的 alpha 6 版本，您可以查看 here 。这个错误实际上已通过此更新解决:

Changes (features ported from nw12)

• nwjc: compile JS to machine code for source code protection
• nw.Tray fix
• 'single-instance' support ('true' only)
• 'user-agent' in manifest
• 'dom_storage_quota' and 'additional_trust_anchors' in manifest
• Fix 'child_process.fork'
• Fix: unable to launch in some Linux distributions
• nw.App methods: argv, clearCache, setProxyConfig, addOriginAccessWhitelistEntry, removeOriginAccessWhitelistEntry, part of 'open' event
• support migrating localstorage data file on app start
• nw-gyp updated to 0.13.0: Fix native module build support

所以，这是我正在使用的 alpha 版本的一个错误，今天已解决。
