我正在玩Sinatra,我想让我的一条路线不区分大小写.我尝试添加这样的路线:
get "(?i)/tileflood/?" do
end
但它与预期的/ tileflood的任何排列都不匹配.我在rubular.com上测试了以下正则表达式,它匹配得很好.我错过了什么吗？
\/(?i)tileflood\/?
你想要一个真正的正则表达式:
require 'sinatra'
get %r{^/tileflood/?$}i do
request.url + "\n"
end
证明:
smagic:~ phrogz$ curl http://localhost:4567/tileflood
http://localhost:4567/tileflood
smagic:~ phrogz$ curl http://localhost:4567/tIlEflOOd

smagic:~ phrogz$ curl http://localhost:4567/TILEFLOOD/
http://localhost:4567/TILEFLOOD/
smagic:~ phrogz$ curl http://localhost:4567/TILEFLOOD/z
