如何从 Sinatra 中的 URL 检测语言 [英] How to detect language from URL in Sinatra

问题描述

我有一个多语言网站，我将语言放在 URL 中，例如 domain.com/en/.当用户没有在 URL 中输入语言时，我想将他重定向到主要语言的页面，例如domain.com/posts".到domain.com/en/posts".使用 Sinatra 有没有简单的方法来做到这一点?

I have a multi-language website and I'm puting the language in the URL like domain.com/en/. When the user doesn't put the language in the URL I want to redirect him to the page in the main language like "domain.com/posts" to "domain.com/en/posts". Is there an easy way to do this with Sinatra?

我有一百多条路线.所以对每条路线都这样做并不是一个很好的选择.

I have more than one hundred routes. So doing this for every route is not a very good option.

获取/:locale/posts"做...结束

get "/:locale/posts" do... end

获取/posts"做...结束

get "/posts" do... end

有人可以帮我吗?

谢谢

推荐答案

使用前置过滤器，有点像这样:

Use a before filter, somewhat like this:

set :locales, %w[en sv de]
set :default_locale, 'en'
set :locale_pattern, /^/?(#{Regexp.union(settings.locals)})(/.+)$/

helpers do
  def locale
    @locale || settings.default_locale
  end
end

before do
  @locale, request.path_info = $1, $2 if request.path_info =~ settings.locale_pattern
end

get '/example' do
  case locale
  when 'en' then 'Hello my friend!'
  when 'de' then 'Hallo mein Freund!'
  when 'sv' then 'Hallå min vän!'
  else '???'
  end
end

随着即将发布的 Sinatra，您将能够做到这一点:

With the upcoming release of Sinatra, you will be able to do this:

before('/:locale/*') { @locale = params[:locale] }
