mod_rewrite的preFIX问题 [英] mod_rewrite prefix problem

问题描述

我在使用mod_rewrite的一些困难。我的目录结构（它的一部分）是：

I'm having some difficulties with mod_rewrite. My directory structure (part of it) is:

index.php
.htaccess
app
  controllers
  models
  views
  ...
  public
    javascripts
    stylesheets
    foo
      bar

所以，你可以看到，所有的静态文件都在app /公众。这就是我喜欢它的原因路由请求，如：

So, as you can see, all static files are in app/public. That's the reason I would like to route requests like:

http://www.example.com/images/logo.png => app/public/images/logo.png  
http://www.example.com/javascripts/app.js => app/public/javascripts/app.js  
http://www.example.com/uploads/blog/something => app/public/uploads/blog/something

如果该文件不存在，那么它应该路由到index.php，如：

If that file doesn't exist, then it should route to index.php, like:

http://www.example.com/news/show/42 => index.php 
(Because file app/public/news doens't exist)

所以，这是我目前的.htaccess，但我认为它可以更优雅的方式来完成。

So, this is my current .htaccess, but I think it can be done in more elegant way.

RewriteEngine on
RewriteRule (png|jpg|gif|bmp|ico)$ app/public/images/$1/$2.$3 [L]
RewriteRule ([^/.]+).js$ app/public/javascripts/$1.js [L]
RewriteRule ([^/.]+).css$ app/public/stylesheets/$1.css [L]
RewriteRule ^(.*)$   index.php    [NC,L,QSA]

此外，问题与这一个时，它只能处理图像，JavaScript和样式表，但不是所有的其他文件。

Also, problem with this one is, it only handles images, javascripts and stylesheets, but not all other files.

我知道有：

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d

不过，我不知道如何将它们与preFIX应用程序/公/路线？我想：

But, I don't know how to route them with prefix "app/public/"? I tried:

RewriteCond app/public/%{SCRIPT_FILENAME} !-f
RewriteCond app/public/%{SCRIPT_FILENAME} !-d

不过，这是行不通的！我也尝试过使用的RewriteBase，但没有成功。

But it doesn't work! I also tried using RewriteBase, but it didn't work out.

编辑：
我使用mod_expires，我真的很想来自动请求，如：

I'm using mod_expires, and I'd really like to automate requests like:

http://www.example.com/images/logo.42.png => app/public/images/logo.png  
http://www.example.com/javascripts/app.42.js => app/public/javascripts/app.js  

所以，你可以看到，我想有文件名和扩展名之间的可选号码，而且这个数字应该被忽略（只用于未来到期）。

So, as you can see, I would like to have optional number between filename and extension, and that number should be ignored (it is only used for future expires).

previously，我发现：

Previously, I found:

RewriteRule ^(.*)\.(\d+)(_m_\d+)?\.([^\.]+)$ $1.$4 [QSA]  

但我实在不明白它是如何工作？它总是在我的例子（也许多个扩展名）的工作？

But I don't really understand how it works and does it always work in my example (multiple extensions maybe)?

谢谢！

推荐答案

试试这个来代替：

/的.htaccess

RewriteEngine on
RewriteRule    ^$ app/public/    [L]
RewriteRule    (.*) app/public/$1 [L]

/app/.htaccess

RewriteEngine on
RewriteRule    ^$ public/    [L]
RewriteRule    (.*) public/$1 [L]

/app/public/.htaccess

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

最后，创建一个的index.php 在 / APP /公/ ，然后把一个调度员在这里：

Finally, create an index.php in your /app/public/ and put a dispatcher here:

<pre>
<?php

function dispatch($action, $request) {

    echo 'action: ' . $action;
    echo "\nparameters: " ;
    print_r($request);
}

$fragments = explode('/', $_GET['url']);
dispatch($fragments[0], array_slice($fragments, 1));

?>
</pre>

现在说尝试访问：

# these will go through php
/controller/action
/post/create
/post/delete/1

# these are static files
/stylesheets/
/foo/bar/myfile.txt
