如何通过文件扩展名确定mime类型? (露比) [英] How to determine mime type by the file extension? ( Ruby )

问题描述

我已经在stackoverflow上看到过类似的问题，但对于ruby来说却一无是处.

I've seen questions like this on stackoverflow but nothing was for ruby.

所以我有这样的文件扩展名:

So I have file extensions like these:

css，html，js，json

我想将它们转换为:

text/css，text/html，text/javascript，application/json

我想用红宝石实现这一目标.

I want to achieve this in ruby.

因此，在编写此代码之后:

So after writing this:

ext_to_mime("css")

我应该得到:

text/css

如果有任何瑰宝，也欢迎他们.

If there are any gems for this they are also welcome.

推荐答案

您可以使用 mime-types gem:

You could use the mime-types gem:

puts MIME::Types.type_for('css')
  => [text/css]
