Created April 10, 2014 13:12 — forked from dahlia/lisp.rb
# 30 minutes Lisp in Ruby
# Hong Minhee <http://dahlia.kr/>

#
# [:def, :factorial,
# [:lambda, [:n],
# [:if, [:"=", :n, 1],
# 1,

Routes

小心地使用 Match(Rails 3 已实现)

Rails 3 提供了 match 方法供我们自定义 routes,然而我们要小心使用它以避免“跨站脚本攻击”(XSS Attack)。比如像这样的 routes:

注:(r3 代表 Rails 3,r4 代表 Rails 4)

# routes.rb
