codeigniter中的产品详细信息页面路由

在我的本地站点中

http://localhost/giftsware/nl/products/details/2382

这是我的产品描述页面的浏览器url现在我想要更多的用户友好的产品描述页面的网址。我想将上面的url更改为

http://localhost/giftsware/products/2382

我尝试通过添加将所有呼叫路由到详细信息

$route['products/（：any）']="nl/products/details/$1"；

这在routes.php文件中，但它给了我404错误。可能出现的问题是什么？我该如何解决？

这是我完整的路线文件代码

$route['(:any)/products/(:num)'] = "products/details/$2";
$route['default_controller'] = "pages";
$route['404_override'] = '';
$route['^en/admin/([a-zA-Z_-]+)/(:any)']    = '$1/admin/$2';
$route['^en/admin/(login|logout)']          = 'admin/$1';
$route['^en/admin/([a-zA-Z_-]+)']           = '$1/admin/index';
$route['^nl/admin/([a-zA-Z_-]+)/(:any)']    = '$1/admin/$2';
$route['^nl/admin/(login|logout)']          = 'admin/$1';
$route['^nl/admin/([a-zA-Z_-]+)']           = '$1/admin/index';
$route['admin']                         = 'admin'; 
$route['pages/(:any)'] = "pages/index/$1";

$route['^nl/(.+)$'] = "$1";
$route['^en/(.+)$'] = "$1";

$route['^nl$'] = $route['default_controller'];
$route['^en$'] = $route['default_controller'];

$route['^nl/products/details/('d+)$'] = 'products/$1';
