ruby-on-rails - redirect_to 自定义 http header

Question

在我当前的项目中，在为 http 基本身份验证重定向时需要设置自定义 http header 变量。我可以为自定义 header 指示 redirect_to 吗？

谢谢。

Rails 允许您在重定向时添加自定义 header 。在 Rails guides 中进行了讨论.

10.2.1 Setting Custom Headers

If you want to set custom headers for a response then response.headers is the place to do it. The headers attribute is a hash which maps header names to their values, and Rails will set some of them automatically. If you want to add or change a header, just assign it to response.headers

所以你的操作代码最终会是这样的:

def some_action
  # do_some_work

  response.headers["your-key"] = "some value"
  redirect_to url
end
