表格数据是通过会话还是参数传递的？(Is form data passed through session or params?)

 我不理解以下应用程序中session和params之间的区别。 
 
 
 
 用户提交新的电影表单。 相关控制器如何访问电影的标题？ 
 
 
 
  
 session['title'] 
 
  
 session.title 
 
  
 params['title'] 
 
  
 params.title 
 
  
 上述所有的 
 
 
 
 
 基于StackOverflow答案在Controller类中的session和params之间的差异 ： 
 
 
 
 params存在于表单的url或post体中，因此在查询完成后它就会消失。 
 
 
 会话在多个请求之间保持不变（信息通常存储在cookie中，但这取决于您的配置）。 
 
 
 简而言之： 
 
 
 
  
 params：仅一个请求（创建一个对象，访问一个特定页面） 
 
  
 session：要保留的信息（购物车，登录用户..） 
 
 
 
 
 我在测验中选择了（1） session ['title']并得到了错误的答案。 我选择了（1）因为我认为它涉及访问必须持久的信息。 
 
 我是否误解了这个问题，也许这只是“只有一个请求”，所以答案应该是（3） params['title'] ？ 

I am not understanding the difference between session and params in the following application.
 
 
 
A user submits a new movie form. How would the associated controller access the title of the movie?
 
 
 
  
session['title']
 
  
session.title
 
  
params['title']
 
  
params.title
 
  
All of the above
 
 
 
 
Based on the StackOverflow answer at Difference between session and params in Controller class:
 
 
 
params live in the url or in the post body of a form, so it vanishes as soon as the query is made.
 
 
Session persists between multiple requests (the info are often stored in cookies but this depends on your configuration).
 
 
To be short:
 
 
 
  
params: one request only (creation of one object, access to one particular page)
 
  
session: info to be persisted (cart, logged user..)
 
 
 
 
I chose (1) session ['title'] on the quiz and got the answer wrong. I chose (1) because I thought it involved accessing information that had to persist.
 
Am I misinterpreting the question and maybe this falls more under "one request only" so the answer should be (3) params['title']?
