如何在同一个 Rails 控制器动作中处理多个 HTTP 方法

问题描述：

假设我想在同一个 URL 上同时支持 GET 和 POST 方法.我将如何在 Rails 控制器操作中处理它?

Let's say I want to support both GET and POST methods on the same URL. How would I go about handling that in a rails controller action?

答

你可以使用 request.post 来检查它是否是一个帖子?

You can check if it was a post using request.post?

if request.post?
  #handle posts
else
  #handle gets
end

要使您的路线生效:

resources :photos do
  member do
    get 'preview'
    post 'preview'
  end
end
