我正在使用LEMP（Linux Nginx MySQL PHP）。
我正在尝试按照此处的教程：http://www.codeigniter.com/user_guide/tutorial/static_pages.html
这是我的控制器/ Pages.php
<?php
class Pages extends CI_Controller {
public function view($page = 'home') {
if ( ! file_exists(APPPATH.'/views/pages/'.$page.'.php'))
{
// Whoops, we don't have a page for that!
show_500();
}
show_500();
$data['title'] = ucfirst($page); // Capitalize the first letter
$this->load->view('templates/header', $data);
$this->load->view('pages/'.$page, $data);
$this->load->view('templates/footer', $data);
}
}
?>
在config / routes.php中，这是默认控制器：
$route['default_controller'] = 'welcome';
现在，当我去
http://127.0.0.1/CodeIgniter-3.0.0/index.php
我得到一个屏幕上写着：
Welcome to CodeIgniter!
The page you are looking at is being generated dynamically by CodeIgniter.
If you would like to edit this page you'll find it located at:
application/views/welcome_message.php
The corresponding controller for this page is found at:
application/controllers/Welcome.php
If you are exploring CodeIgniter for the very first time, you should start by reading the User Guide.
但是，当我去：
http://127.0.0.1/CodeIgniter-3.0.0/index.php/pages
或
http://127.0.0.1/CodeIgniter-3.0.0/index.php/pages/view
我收到404错误。我没有在Pages类的任何地方引发404错误，所以我假设我的Pages类甚至没有被调用。知道为什么我收到404错误/为什么我的Pages类没有被调用？
编辑：
http://127.0.0.1/CodeIgniter-3.0.0/index.php/welcome
和
http://127.0.0.1/CodeIgniter-3.0.0/index.php/welcome/index
也会返回404错误。这很奇怪，因为在Welcome.php中它说：
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Welcome extends CI_Controller {
/**
* Index Page for this controller.
*
* Maps to the following URL
* http://example.com/index.php/welcome
* - or -
* http://example.com/index.php/welcome/index
* - or -
* Since this controller is set as the default controller in
* config/routes.php, it's displayed at http://example.com/
编辑2：Nginx抛出了404.我认为这可能与我的Nginx配置有关，这就是：
# You may add here your
# server {
# ...
# }
# statements for each of your virtual hosts to this file
##
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.

#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.

#}
我想也许问题出在这一部分：
location / {
# First attempt to serve request as file, then
# as directory, then fall back to displaying a 404.
try_files $uri $uri/ =404;
# Uncomment to enable naxsi on this location
# include /etc/nginx/naxsi.rules
}
可能是因为Nginx首先尝试将以下URL作为文件和目录提供服务
http://127.0.0.1/CodeIgniter-3.0.0/index.php/welcome/index
因为上面的URL既不是文件也不是目录，Nginx会抛出404？
答案 0 :(得分：0)
如果您使用的是unix系统，则大小写会导致此问题。核实。它可能会奏效。尝试http://127.0.0.1/CodeIgniter-3.0.0/index.php/Pages（作为控制器的大写字母P的名称是Page not page）。
它奇怪但同样的问题发生在我身上，我能够以这种方式排除故障并解决问题。我不得不用小写字母重命名控制器名称。

试试这个
<?php
class Pages extends CI_Controller {
public function view($page = 'home') {
if ( ! file_exists(APPPATH.'/views/pages/'.$page.'.php'))
{
// Whoops, we don't have a page for that!
show_404();
}
//show_500(); comment this line
$data['title'] = ucfirst($page); // Capitalize the first letter
$this->load->view('templates/header', $data);
$this->load->view('pages/'.$page, $data);
$this->load->view('templates/footer', $data);
}
}
?>
注意：找不到网页错误为
404而非500
