404 Page Not Found 找不到您请求的页面。- CodeIgniter

Question

大家好，我尝试在 CodeIgniter 1.7.1 上工作，我已经完成了逐步安装 但它显示错误 404 页面未找到 未找到您请求的页面。

这是我使用的代码

控制器 home.php

class Home extends Controller {
       function __construct()
       {
        parent:: __construct();
        //$this->output->enable_profiler();
        $this->load->library('DX_Auth'); 

    } 

模型 homemodel.php

class HomeModel extends Model {


    function __construct()
    {
        // Call the Model constructor
        parent::Model();

    }

.htaccess

RewriteCond $1 !^(index\.php|assets|xcache|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L] 

我使用本地主机“XAMPP”

请帮帮我

和主index.php

<?php

    error_reporting(E_ALL);

    $system_folder = "system";


    $application_folder = "application";


if (strpos($system_folder, '/') === FALSE)
{
    if (function_exists('realpath') AND @realpath(dirname(__FILE__)) !== FALSE)
    {
        $system_folder = realpath(dirname(__FILE__)).'/'.$system_folder;
    }
}
else
{
    // Swap directory separators to Unix style for consistency
    $system_folder = str_replace("\\", "/", $system_folder); 
}


define('EXT', '.'.pathinfo(__FILE__, PATHINFO_EXTENSION));
define('FCPATH', __FILE__);
define('SELF', pathinfo(__FILE__, PATHINFO_BASENAME));
define('BASEPATH', $system_folder.'/');

if (is_dir($application_folder))
{
    define('APPPATH', $application_folder.'/');
}
else
{
    if ($application_folder == '')
    {
        $application_folder = 'application';
    }

    define('APPPATH', BASEPATH.$application_folder.'/');
}

服务器错误致命错误：在第 21 行的 /hermes/bosoraweb075/b2180/ipg.djsaifnycom/paly/system/application/controllers/home.php 中找不到类“Memcache”

        $this->template->write('title', 'Home');
        $this->template->write_view('content', 'home/index', $data, TRUE);
        $this->template->render();
    }



    //$this->load->view('home/index', $data);
    //$this->output->enable_profiler(TRUE);
}

这条线是 $data['memcache'] = new Memcache;

Answer 1

您可能还想检查您的httpd.conf 文件，看看是否允许 apache “尊重”您的 .htaccess 文件。搜索AllowOverride 命令并将其从AllowOverride None（默认）更改为AllowOverride All。

另外：之后不要忘记重新启动 httpd 服务器。

Answer 2

也许 .htaccess 不在正确的目录中。你可能想检查它，应该在你的项目目录中。如果是的话，

把它放在你的 .htaccess 文件中

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
