CodeIgniter 路由和 404 自定义错误

技术标签:
【中文标题】CodeIgniter 路由和 404 自定义错误【英文标题】：CodeIgniter Routing and 404 Custom Errors 【发布时间】：2016-08-04 15:53:29 【问题描述】：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。一切正常。
然而，几个月前，我想我会添加一个自定义 404 页面。我做到了，一切似乎都很好。
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，但会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，但这显然是一场噩梦，因为我现在没有从所有搜索引擎列表中编入索引！！！域名是http://citylightstours.com
ROUTES.PHP
<?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";

我有一个 MY_Router.php 文件来处理客户 404 页面，想知道这是否错误地设置了 404 http 状态？？
MY_Router.php 文件：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class MY_Router extends CI_Router
var $error_controller = 'error';
var $error_method_404 = 'error_404';
function My_Router()
parent::CI_Router();
// 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))
return $segments;
// Is the controller in a sub-folder?
if (is_dir(APPPATH.'controllers/'.$segments[0]))
// Set the directory and remove it from the segment array
$this->set_directory($segments[0]);
$segments = array_slice($segments, 1);
if (count($segments) > 0)
// Does the requested controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$segments[0].EXT))
return $this->error_404();
else
$this->set_class($this->default_controller);
$this->set_method('index');
// Does the default controller exist in the sub-folder?
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$this->default_controller.EXT))
$this->directory = '';
return array();
return $segments;
// Can't find the requested controller...
return $this->error_404();
function error_404()
$this->directory = "";
$segments = array();
$segments[] = $this->error_controller;
$segments[] = $this->error_method_404;
return $segments;
function fetch_class()
// if method doesn't exist in class, change
// class to error and method to error_404
$this->check_method();
return $this->class;
function check_method()
$ignore_remap = true;
$class = $this->class;
if (class_exists($class))
// methods for this class
$class_methods = array_map('strtolower', get_class_methods($class));
// ignore controllers using _remap()
if($ignore_remap && in_array('_remap', $class_methods))
return;
if (! in_array(strtolower($this->method), $class_methods))
$this->directory = "";
$this->class = $this->error_controller;
$this->method = $this->error_method_404;
include(APPPATH.'controllers/'.$this->fetch_directory().$this->error_controller.EXT);
function show_404()
include(APPPATH.'controllers/'.$this->fetch_directory().$this->error_controller.EXT);
call_user_func(array($this->error_controller, $this->error_method_404));
/* End of file MY_Router.php */
/* Location: ./system/application/libraries/MY_Router.php */
有人可以帮忙吗？？
谢谢
【问题讨论】：
我认为它正在查找页面并返回它，但将服务器响应代码设置为 404。它将在 CodeIgniter 中设置在哪里？？？？ 【参考方案1】：您的路线需要修复：-
$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：-
http://www.codeigniter.com/userguide2/general/routing.html
根据您的路由，每种语言都有一个控制器。例如（enController、deController、esController 等...），我假设你没有，你只有一个内容控制器。

【讨论】：
您好，codenathan，感谢您抽出宝贵时间回复。我读了那篇文章，看不出我的路线有什么问题——它链接到内容类和语言方法。我不认为它指定了不同的内容控制器 - 只是一个具有不同方法的控制器......？无论如何，我删除了对路线语言方面的引用，但我仍然得到 404 服务器响应，并且正确的页面显示为人类自定义页面....有什么想法吗？？ 抱歉，我看错了，您能发布您的内容控制器代码吗？ 嗨，codenathan，我可以，但我认为这与我的内容控制器无关。一切正常，因为它正确运行并从数据库中获取正确的页面数据并正确显示它。问题是它以 404 而不是 200 的 http 状态显示它。我有一个自定义错误页面，并认为它可能与我为了执行此自定义 404 而拥有的 MY_Router.php 文件有关。我会发布MYRouter 代码...以上是关于CodeIgniter 路由和 404 自定义错误的主要内容，如果未能解决你的问题，请参考以下文章
