Gem Grape 如何以元编程的方式给 route 增加 callback?
Just like following:
add after callback to UserApi route with namespace and route "user_api/sign_in"
add_callback :after, "user_api/sign_in" do |params|
do_something
end
我看了下 grape 的代码，表示有点看不懂。。
你要的需求 Grape 已经有方案了啊 你看看https://github.com/ruby-grape/grape#before-and-after
