Rendering file with MIME Type in rails
提问by user38684
Here's the code:
这是代码:
render :file => @somedir + "/blah.xml"
...but the resulting MIME type is text/html when I check in FireBug. How do I specify a MIME type in this case?
...但是当我签入 FireBug 时,生成的 MIME 类型是 text/html。在这种情况下如何指定 MIME 类型?

Actually there are two ways to set the content-type (I think this is what you mean by mime-type). You should use the second option, if it works for your Rails version.
实际上有两种设置内容类型的方法(我认为这就是你所说的 mime-type)。您应该使用第二个选项,如果它适用于您的 Rails 版本。
class FileController < ApplicationController
def index
filename = 'some.xml'
extname = File.extname(filename)[1..-1]
mime_type = Mime::Type.lookup_by_extension(extname)
content_type = mime_type.to_s unless mime_type.nil?
# 1
#headers['Content-Type'] = content_type
#render :file => filename
# 2
render :file => filename, :content_type => content_type
end
end
Hope this helps!
希望这可以帮助!

Per http://api.rubyonrails.org/classes/Mime/Type.html, you could specify it like so:
根据http://api.rubyonrails.org/classes/Mime/Type.html,您可以像这样指定它:
render file: @somedir + "/blah.xml", mime_type: Mime::Type.lookup("text/xml")
