Ruby on Rails 301 重定向 [英] Ruby on Rails 301 redirection

问题描述

我在某些模型中添加了 slug，但由于 SEO，我需要从旧链接进行 301 重定向:旧:

I added slugs to some of the models, but because of SEO I need to do 301 redirection from old links: old:

http://host.com/foo/1

新:

http://host.com/foo/foo_slug

问题:在这种情况下如何实现301重定向?是否可以从大写链接实现 301 重定向?像这样:

question: how to implement 301 redirection in this case? and is it possible to implement 301 redirection from uppercased link? Like this:

http://host.com/foo/FOO_SLUG -> http://host.com/foo/foo_slug

推荐答案

您应该能够通过将其添加到您的控制器操作来重定向状态 301:

You should be able to redirect with status 301 by adding this to your controller action:

redirect_to "http://host.com/foo/foo_slug", :status => 301

请参阅 redirect_to 的 API 文档，了解详情.

See the API documentation for redirect_to for details.

并且将大写 URL 重定向到小写版本应该没有问题，尽管这可能由 HTTP 服务器层的某些东西更好地处理，例如 Apache mod_rewrite 规则.

And there should be no problem with redirecting upper-cased URLs to lowercased versions, although this may be better handled by something at the HTTP server layer such as Apache mod_rewrite rules.
