get '/foo', :agent => /Songbird (\d.\d)[\d\/]*?/ do "You're using Songbird version #{params[:agent][0]}" end

get '/foo' do # Matches non-songbird browsers end

request.user_agent 匹配 /Songbird (\d.\d)[\d\/]*?/的 => "You're using Songbird version #{params[:agent][0]}", 否则走下面的

#5 楼 @dddd1919 Songbird 我以为是个普通的字符串

#6 楼 @shangrenzhidao 它在这里面的作用确实就是个具有写实意义的普通字符串 😊
