用 apache2 重写 Url

Question

我正在试验 CodeIgniter PHP 框架，这个框架的工作原理是：

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

所以，我尝试从那里删除 index.php 部分。到目前为止，我做了这些：

1. 将$config['index_page'] = "index.php"; 改为$config['index_page'] = "";

2. 从$config['uri_protocol'] = "AUTO"; 制作$config['uri_protocol'] = "REQUEST_URI";

3. 通过“a2enmod rewrite”启用 apache mod_rewrite

4. 将 .htaccess 文件放入/ci 目录：

   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. 当然还要重启 apache 服务器

这是我的 apache 日志，配置如下：

这是 Firefox 中的结果：

404 未找到：
在此服务器上未找到请求的 URL /index.php。

那么，我应该怎么做（或者我哪里错了）才能让这些 URL 工作？ http://localhost:7777/~dhalsim/ci/blog/ 而不是 http://localhost:7777/~dhalsim/ci/index.php/blog/

Answer 1

我是这样解决的：

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

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

然后在config.php文件中

/*
|--------------------------------------------------------------------------
| 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'] = "";

更新

在 routes.php 文件中：

//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

使用以下重写规则：

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]

为了让它工作，你应该在不同的端口上设置你的 CodeIgniter 应用程序或使用 /etc/hosts 给它一个简单的虚拟主机（127.0.0.1 ci 和 http://ci:7777/ Apache 设置为使用 ci 虚拟主机。 ）。然后您可以将基本 url 设置为 / 而不必担心。否则你将不得不处理令人困惑的目录问题和 mod_rewrite。
