mod_rewrite 前缀问题 [英] mod_rewrite prefix problem

问题描述

我在使用 mod_rewrite 时遇到了一些困难.我的目录结构(其中的一部分)是:

index.php.htaccess应用程序控制器楷模意见...民众javascripts样式表富酒吧

因此，如您所见，所有静态文件都在 app/public 中.这就是我想路由请求的原因:

http://www.example.com/images/logo.png =>应用程序/公共/图像/标志.pnghttp://www.example.com/javascripts/app.js =>应用程序/公共/javascripts/app.jshttp://www.example.com/uploads/blog/something =>应用程序/公共/上传/博客/东西

如果该文件不存在，那么它应该路由到 index.php，例如:

http://www.example.com/news/show/42 =>索引.php(因为文件 app/public/news 不存在)

所以，这是我目前的 .htaccess，但我认为它可以以更优雅的方式完成.

RewriteEngine onRewriteRule (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/$1.css [L]重写规则 ^(.*)$ index.php [NC,L,QSA]

另外，这个问题是，它只处理图像、javascripts 和样式表，而不是所有其他文件.

我知道有:

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

但是，我不知道如何使用前缀app/public/"来路由它们?我试过了:

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

但它不起作用！我也尝试过使用 RewriteBase，但没有成功.

我正在使用 mod_expires，我真的很想自动化请求，例如:

http://www.example.com/images/logo.42.png =>应用程序/公共/图像/标志.pnghttp://www.example.com/javascripts/app.42.js =>应用程序/公共/javascripts/app.js

所以，正如你所看到的，我希望在文件名和扩展名之间有一个可选的数字，这个数字应该被忽略(它只用于未来的到期).

之前，我发现:

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

但我真的不明白它是如何工作的，它在我的例子中是否总是有效(可能有多个扩展)?

谢谢！

解决方案

试试这个:

/.htaccess

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

/app/.htaccess

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

/app/public/.htaccess

RewriteEngine OnRewriteCond %{REQUEST_FILENAME} !-dRewriteCond %{REQUEST_FILENAME} !-f重写规则 ^(.*)$ index.php?url=$1 [QSA,L]

最后，在您的 /app/public/ 中创建一个 index.php 并在此处放置一个调度程序:

<?php函数调度($action，$request){回声'动作:'.$动作;echo "\n参数:" ;打印_r($请求)；}$fragments = expand('/', $_GET['url']);dispatch($fragments[0], array_slice($fragments, 1));?>

现在说尝试访问:

# 这些将通过 php/控制器/动作/发布/创建/发布/删除/1# 这些是静态文件/样式表//foo/bar/myfile.txt

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

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

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)

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]

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

I know there is:

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

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

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

EDIT:
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  

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, I found:

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

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

Thanks!

解决方案

Try this instead:

/.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]

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>

Now say try accessing:

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

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