codeigniter正则表达式的路由 [英] Codeigniter regexp routing

问题描述

我有一个问题，像这样的路由：

I have a problem with routing like this:

$route['(/[a-z]{2}/)'] = 'locale/somepage';

和在.htaccess

And in .htaccess

RewriteEngine on
RewriteBase /
RewriteRule ^(/[a-z]{2}/)$ /index.php/locale/somepage

我需要更换URL（类或控制器）的第一部分，并调用另一个控制器。例如，我需要网址 / EN /页将呼叫控制器的区域设置，但URL不需要更改。

I need replace first section of url (class or controller) and call an another controller. For example, I need to url as /en/page will call controller locale, but url need not be changed.

这code不工作。如果我尝试只用routes.php文件或仅htaccess的，它不是工作压力太大。 我怎样才能使它工作？

This code is not working. And if I try use only routes.php or only .htaccess, it not working too. How I can make it work?

推荐答案

我想你写你的htaccess正则表达式规则错误。你不需要写它作为一个PHP的正则表达式规则，尝试重写它不会在你的htaccess斜线：

I think you've written your htaccess regexp rule wrong. You don't need to write it as a PHP regexp rule, try to rewrite it without the slash in your htaccess:

RewriteRule ^([a-z]{2})/page$ /index.php/locale/somepage

这将发送任何 http://mypage.com/en/page 来的index.php /区域/ SomePage的。

This will send any http://mypage.com/en/page to index.php/locale/somepage.

通过这条规则，CI将接收URL 的index.php /区域/ SomePage的。在这一点上，CI会去 routes.php文件，并检查是否有任何规则调用特定的控制器。如果不是，它会尝试去到一个名为区域控制器，加载一个名为方法 SomePage的。

With that rule, CI will receive the url index.php/locale/somepage. At that point, CI will go to routes.php and will check if there are any rule to call a specific controller. If not, it'll try to go to a controller called locale, to load a method called somepage.

所以，你不需要使用 routes.php文件再修改Apache的URL，你receving调用另一个控制器。

So, you don't need to use routes.php to modify again the apache url that you're receving to call another controller.
