CodeIgniter路由和404自定义错误

时间:2016-04-13 13:43:04

标签: .htaccess codeigniter http-status-code-404 url-routing codeigniter-2

我使用CodeIgniter。

我使用routes.php文件根据url的结构将某些url路由到不同的文件。一切都很好。

然而,几个月前,我想我会添加一个自定义的404页面。我做了,事情似乎工作正常。

但是,我刚刚意识到我网站上的每个页面(主页除外)都会给出404错误的服务器响应,并向人类用户显示正确的页面作为自定义页面!

我不知道这是怎么回事,但它显然是一场噩梦,因为我现在没有从所有搜索引擎列表索引!域名为http://citylightstours.com

routes.php文件

<?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/*
| -------------------------------------------------------------------------
| URI ROUTING
| -------------------------------------------------------------------------
| This file lets you re-map URI requests to specific controller functions.
|
| Typically there is a one-to-one relationship between a URL string
| and its corresponding controller class/method. The segments in a
| URL normally follow this pattern:
|
|   example.com/class/method/id/
|
| In some instances, however, you may want to remap this relationship
| so that a different class/function is called than the one
| corresponding to the URL.
|
| Please see the user guide for complete details:
|
|   http://codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There area two reserved routes:
|
|   $route['default_controller'] = 'welcome';
|
| This route indicates which controller class should be loaded if the
| URI contains no data. In the above example, the "welcome" class
| would be loaded.
|
|   $route['404_override'] = 'errors/page_missing';
|
| This route will tell the Router what URI segments to use if those provided
| in the URL cannot be matched to a valid route.
|
*/

$route['default_controller'] = "content";
$route['en/(:num)/(:any)'] = "content/en/$1";
$route['de/(:num)/(:any)'] = "content/de/$1";
$route['es/(:num)/(:any)'] = "content/es/$1";
$route['it/(:num)/(:any)'] = "content/it/$1";
$route['ar/(:num)/(:any)'] = "content/ar/$1";

我有一个MY_Router.php文件来处理客户404页面,并想知道这是否正在设置404 http状态?

MY_Router.php文件:

    // this is just the same method as in Router.php, with show_404() replaced by $this->error_404();
    function _validate_request($segments)
    {
        // Does the requested controller exist in the root folder?
        if (file_exists(APPPATH.'controllers/'.$segments[0].EXT))

您的路线需要修理: -

$route['en/(:num)/(:any)'] = "content/en/$1";
$route['de/(:num)/(:any)'] = "content/de/$1";
$route['es/(:num)/(:any)'] = "content/es/$1";
$route['it/(:num)/(:any)'] = "content/it/$1";
$route['ar/(:num)/(:any)'] = "content/ar/$1";

请阅读: -

根据您的路由,您可以使用每种语言的控制器。例如(enController,deController,esController等...),我认为你不具备内容控制器。
