I thkink this is a easy question, but I didn't find the solution. 我认为这是一个简单的问题,但我找不到解决方案。 In Rails, How can I get my application URL inside routes?
在Rails中,如何在路由中获取应用程序URL?
Something like: 就像是:
get '/foo', to: redirect("http://whatheverurl.com/?bar=#{MY_APPLICATION_URL}")
match '/foo', :to => redirect { |params, request|
"http://whatheverurl.com/?bar=#{request.env['HTTP_HOST']}"
}
You could do something like this: 你可以这样做:
match "/web_site", :to => proc { |env|
[301, {
'Location' => "http://www.greenviewdata.com?from=#{env['HTTP_HOST']}"
}, ["Go here instead: http://www.greenviewdata.com?from=#{env['HTTP_HOST']}"]]
}
