ruby-on-rails - 如何使用涉及 Unicode 的 Assets 名称？

Question

我有很多需要支持的音频文件名，都是用中文拼音写的，例如wǒ shì xuésheng.mp3 .将这些转换为 Assets 路径或处理生成的路径似乎存在问题，因为

http://localhost:3000/assets/wǒ shì xuésheng.mp3
http://localhost:3000/assets/w%C7%92+sh%C3%AC+xu%C3%A9sheng.mp3
http://localhost:3000/assets/w%C7%92%20sh%C3%AC%20xu%C3%A9sheng.mp3

不要结果什么。我尝试了 asset_path 和 Rack 编码，但似乎无法访问我的目录结构中的这些文件。为了消除潜在的错误源，我还尝试了一个名为 ma ma.mp3 的文件。在同一目录中，并且该目录加载正常，因此问题似乎出在文件名中的 Unicode 字符上。

有趣的是， File.exists 有效:

File.exists?(File.join(Rails.root, "/app/assets/audios/", "wǒ shì xuésheng.mp3"))

此外，欧洲变音符号工作:

http://localhost:3000/assets/bù.mp3

只是 Unicode 会破坏系统。

我使用的是 Rails 3.2.11 和 Ruby 1.9.3。 (编辑:这个问题即使在 Rails 4.0.2 中仍然存在)

编辑:我怀疑这是 Assets 管道的问题，因为我也无法执行 rake assets:precompile 而我在文件名中有 Unicode 字符，它失败并显示“未定义的方法目录？为 nil:NilClass”。

编辑:这是 rake Assets 的跟踪:预编译:

** Invoke assets:precompile (first_time)
** Execute assets:precompile
C:/RailsInstaller/Ruby1.9.3/bin/ruby.exe C:/RailsInstaller/Ruby1.9.3/bin/rake assets:precompile:all RAILS_ENV=produ
ction RAILS_GROUPS=assets --trace

** Execute assets:precompile:all
** Invoke assets:precompile:primary (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
** Invoke tmp:cache:clear (first_time)

Answer 1

Rails 3.2.x 补丁版本中已经有大量错误修复，可能已经解决了这个问题。这里的其他帖子暗示升级到 3.2.14 修复了这个 UTF-8 URL 编码问题。

我建议升级到 Rails 3.2.15 (当前补丁版本)以查看此问题是否已解决。
