.htaccess重写问题

Question

要么我真的需要回到学校的办公桌，要么有一些奇怪的事情发生。

下不起作用，因为真正的物理文件和目录没有解决：

<IfModule mod_rewrite.c> 
    Options +FollowSymLinks 
    RewriteEngine on 
    RewriteBase/
    RewriteCond %{REQUEST_FILENAME} !-d 
    RewriteCond %{REQUEST_FILENAME} !-f 
    RewriteCond %{REQUEST_FILENAME} !-l 

    # The following rule must not affect real physical files, but does 
    RewriteRule ^(img/.*)$ http://old.site.com/$1 [L,R=301] 

    RewriteRule .* index.php [L] 
</IfModule> 

然而这段代码工作和解决实际文件和文件夹就好了：

<IfModule mod_rewrite.c> 
    Options +FollowSymLinks 
    RewriteEngine on 
    RewriteBase/
    RewriteCond %{REQUEST_FILENAME} !-d 
    RewriteCond %{REQUEST_FILENAME} !-f 
    RewriteCond %{REQUEST_FILENAME} !-l 

    RewriteRule ^(img/.*)$ http://old.site.com/$1 [L,R=301] 

    RewriteCond %{REQUEST_FILENAME} !-d 
    RewriteCond %{REQUEST_FILENAME} !-f 
    RewriteCond %{REQUEST_FILENAME} !-l 

    RewriteRule .* index.php [L] 
</IfModule> 

我是否真的需要在每个RewriteRule之前添加一个新的RewriteCond？

Answer 1

的RewriteCond只适用于第二天重写规则。所以是的，在你的情况下，你需要在每个RewriteRule之前有一个RewriteCond。

但好消息是它可以避免。

如果你想避免写这些多重的RewriteCond你可以这样做，因为这代码：

## If the request is for a valid directory 
RewriteCond %{REQUEST_FILENAME} -d [OR] 
## If the request is for a valid file 
RewriteCond %{REQUEST_FILENAME} -f [OR] 
## If the request is for a valid link 
RewriteCond %{REQUEST_FILENAME} -l 
## don't do anything 
RewriteRule^- [L] 

RewriteRule ^(img/.*)$ http://old.site.com/$1 [L,R=301] 

RewriteRule .* index.php [L] 

Answer 2

是的。

根据一套（一套）RewriteCond s不能有两个RewriteRule s。

从manual的一些话：

Each rule can have an unlimited number of attached rule conditions...

One or more RewriteCond can precede a RewriteRule directive...

The RewriteRule directive [...] can occur more than once, with each instance defining a single rewrite rule...
