重寫URL以Apache2的

Question

我使用CodeIgniter PHP框架的實驗，這個框架的工作原理是：

http://localhost:7777/~dhalsim/ci/index.php/blog

所以，我試圖從那裏取出index.php一部分。到目前爲止，我做這些：

1. 使$config['index_page'] = "index.php";到$config['index_page'] = "";

2. 使$config['uri_protocol'] = "REQUEST_URI";從$config['uri_protocol'] = "AUTO";

3. 通過使阿帕奇mod_rewrite的 「a2enmod rewrite」

4. 把一個.htaccess文件到/ci目錄：

   RewriteEngine on 
   RewriteBase/
   RewriteCond %{REQUEST_URI} ^system.* 
   RewriteRule ^(.*)$ /index.php/$1 [L] 
   RewriteCond %{REQUEST_FILENAME} !-f 
   RewriteCond %{REQUEST_FILENAME} !-d 
   RewriteRule ^(.*)$ index.php?/$1 [L] 
   

5. 當然並重新啓動Apache服務器

這裏是我的Apache日誌進行以下配置：

127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (3) [perdir /home/dhalsim/public_html/ci/] strip per-dir prefix: /home/dhalsim/public_html/ci/blog -> blog

下面是結果在Firefox：

404未找到：
在此服務器上未找到請求的URL /index.php。

那麼，究竟應該怎麼辦？（或者我錯了），以獲得工作這些網址嗎？ http://localhost:7777/~dhalsim/ci/blog/代替http://localhost:7777/~dhalsim/ci/index.php/blog/

Answer 1

這是我如何解決它：

RewriteEngine on 
RewriteCond $1 !^(index\.php|images|flash|css|js|robots\.txt|downloads) 

RewriteRule ^(.*)$ /index.php/$1 [L] 

然後在config.php文件

/* 
|-------------------------------------------------------------------------- 
| Base Site URL 
|-------------------------------------------------------------------------- 
| 
| URL to your CodeIgniter root. Typically this will be your base URL, 
| WITH a trailing slash: 
| 
| http://example.com/ 
| 
*/ 
$config['base_url'] = "http://localhost:7777/~dhalsim/ci/"; 

/* 
|-------------------------------------------------------------------------- 
| Index File 
|-------------------------------------------------------------------------- 
| 
| Typically this will be your index.php file, unless you've renamed it to 
| something else. If you are using mod_rewrite to remove the page set this 
| variable so that it is blank. 
| 
*/ 
$config['index_page'] = ""; 

UPDATE

在routes.php文件文件：

//Point to default controller 
$route['default_controller'] = "site/home"; //Set to your controller 

// Point to the right controller 
$routing_array = array(
      'blog' => 'site/blog', 
     ); // set to your blog controler 

Answer 2

使用以下重寫規則：

RewriteEngine On 
RewriteCond %{REQUEST_FILENAME} -s [OR] 
RewriteCond %{REQUEST_FILENAME} -l [OR] 
RewriteCond %{REQUEST_FILENAME} -d 
RewriteRule ^.*$ - [NC,L] 
RewriteRule ^(.*)$ /index.php/$1 [NC,L] 

爲了這個工作，你應該設置一個不同的端口或使用/ etc/hosts文件在你的笨應用給它一個簡單的虛擬主機（127.0.0.1 ci和http://ci:7777/ Apache設置爲使用ci虛擬主機。）。然後，您可以將基礎網址設置爲/，而不必擔心。否則，你將不得不處理混淆的目錄問題和mod_rewrite。
