使用 .htaccess 路由到 codeigniter 中的两个不同应用程序答案

【问题标题】：Using .htaccess to route to two different applications in codeigniter使用 .htaccess 路由到 codeigniter 中的两个不同应用程序

【问题描述】：

我有两个类似于 example 的 codeigniter 应用程序。我创建了两个index.php 文件，如示例所述（第二个名为 oglasnik.php）。我想调用没有调用所需应用程序的文件名的应用程序。

我以this 为例。所以我现在的 .htaccess 文件是：

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /PublishWall/
    DirectoryIndex indexl.php

    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ indexl.php?/$1 [L]

    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ indexl.php?/$1 [L]

    RewriteCond $1 !^(indexl\.php|oglasnik\.php|images|robots\.txt)
    RewriteRule ^oglasnik$ oglasnik.php [L]

 </IfModule>

 <IfModule !mod_rewrite.c>

    ErrorDocument 404 /index.php
 </IfModule> 
php_value date.timezone "Europe/Ljubljana"
AddDefaultCharset utf-8

当我路由到 oglasnik 时，我得到 404 Page Not Found，不应该这条规则：

RewriteRule ^oglasnik$ oglasnik.php [L]

将其重写为 oglasnik.php。当我去 oglasnik.php 它工作正常。

我也很想知道这个路由实际上是如何工作的。重写的 url 是否再次访问 .htacces 文件，我在 this answer 中看到的。

【问题讨论】：

在您的 oglasnik 规则中，RewriteCond 正在检查 $1，这是在 RewriteRule 中捕获的第一个字符序列 - 但您没有捕获任何内容，因此它永远不会正确，因此出现 404 错误。将 oglasnik 包裹在花括号中可能会产生更好的效果。至于 mod_rewrite 的流程：查看令人难以置信的启发性 flowchart 和 docs。那张流程图真的非常值得一看。
感谢流程图的链接。虽然括号没有帮助。在帖子的编辑中，我将添加此重写的重写日志。
我发现我实际上到达了我想要的 codeigniter 应用程序，但它转到了 404_override

【解决方案1】：

你可能想试试这个：

RewriteCond %{REQUEST_URI} !^(indexl\.php|oglasnik\.php|images|robots\.txt)
RewriteRule ^oglasnik.*$ oglasnik.php?/$1 [L]
