重定向 HTTP 请求，避免控制器操作问题

发布于 2024-11-09 18:18:21 字数 649 浏览 3 评论 0原文

routes.rb 文件中进行了说明，如下所示：

#routers.rb
resources :users

namespace "users" do
  resources :profiles
  ...
end

使用上面的代码，我可以访问以下 URL：

<my_web_site>/users/1
<my_web_site>/users/1/edit
...
# and also
<my_web_site>/users/profiles/1
<my_web_site>/users/profiles/1/edit
...

我正在使用 Ruby on Rails 3。在我的项目中，我有很多类，其中一些类在我想做的是将一些 URL 请求重定向到其他 URL，但如果在 routes.rb 文件中我重定向所有这些，某些控制器操作将无法正常工作，因为这些请求被重定向（GET、POST...）。

我该如何解决这个问题？

PS：我知道（也许）我的路由器声明是错误的，但目前我正在寻找一个简单的解决方案来解决这个问题。不过，欢迎就此事提出建议。

I am using Ruby on Rails 3. In my project I have many classes and some of those are stated in the routes.rb file like the following:

#routers.rb
resources :users

namespace "users" do
  resources :profiles
  ...
end

With the above code I can access the following URLs:

<my_web_site>/users/1
<my_web_site>/users/1/edit
...
# and also
<my_web_site>/users/profiles/1
<my_web_site>/users/profiles/1/edit
...

What I would like to do is to redirect some URL requests to others URL but if in the routes.rb file I redirect all those, some controller actions will not work properly because also those requests are redirected (GET, POST, ...).

How can I solve this issue?

P.S.: I know that (maybe) my router statements are wrong, but at the moment I am looking for a easy solution too the problem. However suggestions about this matter are welcome.

好的，看起来您想要设置一个仅适用于给定路径和一个 HTTP 动词的重定向。这似乎就是您正在寻找的内容：

#routers.rb
resources :users

match "/users/profile/:id" => redirect("/profiles/%{id}"), :via => :get

namespace "users" do
  resources :profiles
  ...
end

根据此路由，命中 /users/profile/1 的每个 GET 请求都将被重定向到 /profiles/1< /code> 而任何 POST、PUT 或 DELETE 请求都不会受到重定向。

仅当请求方法计算给定值时， :via 参数才会执行重定向。它还接受动词数组，例如，您可以重定向 :via =>; [:post, :put]

如果您添加有关您需要的特定重定向的更多详细信息，我们可以创建一个更好的示例。

Ok, looks like you want to set up a redirection that will only apply for to a given path and just one HTTP verb. This seems to be what you are looking for:

#routers.rb
resources :users

match "/users/profile/:id" => redirect("/profiles/%{id}"), :via => :get

namespace "users" do
  resources :profiles
  ...
end

Based on this routes every GETrequest hitting /users/profile/1 will be redirected to /profiles/1 while any POST, PUT or DELETE requests won't be suffering the redirection.

The :via param will execure the redirection only if the request method math the given value. It also accepts an array of verbs so, for example, you can redirect :via => [:post, :put]

If you add more detailed information about the specific redirections that you need we can create a better example.
