ASP.NET MVC - 如何将帖子中的FormCollection数据传递给另一个Action？

Question

I have a page "Results" with a form and when "submit" is clicked, the form is submmited to another Action. So far, so good...

But, this works fine just if user is logged in. If not, he will be redirected to "Login" page and my FormCollection loses its data.

Is there a way to persist this data without using TempData??

Thanks!!

Answer 1

I don't think that's possible. The only thing the system remembers during the redirect to the login page is the 'return url'. No post data is saved (this could be megabytes of data...)

You can use the Session object as alternative, or make sure that the user is logged in before you post.

Or, if it's just a search result, try to live without the POST, and use a GET (which also has other advantages)

Answer 2

我宁愿不允许未经授权的用户访问“结果”页面或至少向他显示消息“请先登录”而不是表格。
