在rewriten文件路径重写规则检查文件是否存在 [英] RewriteRule checking file in rewriten file path exists

问题描述

您

如何使用ModRewrite检查一个缓存文件存在，如果是这样，重写缓存文件否则改写为一个动态的文件。

例如我有以下文件夹结构：

pages.php
缓存/
  页/
   1.HTML
   2.HTML
   textToo.html
   等等

你会如何设置此所以请求的RewriteRules可以发送这样的：

example.com/pages/1

和如果高速缓存文件是否存在重写托特缓存文件，并且如果高速缓存文件不存在，改写到pages.php？p为1

应该是这样的：（注意，这是不行的，不然我也不会问这个）

重写规则^页/([^/\\.]+）缓存/页/ $ 1.HTML [NC，QSA]
的RewriteCond％{} REQUEST_FILENAME -f [NC，OR]
的RewriteCond％{} REQUEST_FILENAME -D [NC]
重写规则缓存/页/([^/\\.]+）HTML pages.php？p = $ 1 [NC，QSA，L]

我能够把粗做到这一点使用PHP，但我认为它必须使用mod_rewrite就可以了。

解决方案

 重写规则^页/([^/\\.]+）缓存/页/ $ 1.HTML [NC，QSA ]＃在这一点上，我们已经重新编写页/ 4缓存/页/ 4.html
的RewriteCond％{} REQUEST_FILENAME！-f＃如果上述的RewriteCond成功，我们没有一个高速缓存，所以重写
＃在pa​​ges.php URI，否则我们脱落月底与去
＃缓存/页/ 4.html
重写规则^缓存/页/([^/\\.]+）HTML pages.php？p = $ 1 [NC，QSA，L]
 

关闭多视图是至关重要的（如果你有他们启用）为好。

 选项-MultiViews
 

否则初始请求（/页/ ...）将获得自动转换的mod_rewrite在踢之前/pages.php，你也可以只重命名pages.php到别的东西（和更新的最后一个重写规则以及）以避免多视图冲突

编辑：我最初包括的RewriteCond ... -d 但它是多余的。

How can you use ModRewrite to check if a cache file exists, and if it does, rewrite to the cache file and otherwise rewrite to a dynamic file.

For example I have the following folder structure:

pages.php
cache/
  pages/
   1.html
   2.html
   textToo.html
   etc.

How would you setup the RewriteRules for this so request can be send like this:

example.com/pages/1

And if the cache file exists rewrite tot the cache file, and if the cache file does not exists, rewrite to pages.php?p=1

It should be something like this: (note that this does not work, otherwise I would not have asked this)

RewriteRule ^pages/([^/\.]+) cache/pages/$1.html [NC,QSA]
RewriteCond %{REQUEST_FILENAME} -f [NC,OR] 
RewriteCond %{REQUEST_FILENAME} -d [NC] 
RewriteRule cache/pages/([^/\.]+).html pages.php?p=$1 [NC,QSA,L]

I can off coarse do this using PHP but I thought it had to be possible using mod_rewrite.

解决方案

RewriteRule ^pages/([^/\.]+) cache/pages/$1.html [NC,QSA]

# At this point, we would have already re-written pages/4 to cache/pages/4.html
RewriteCond %{REQUEST_FILENAME} !-f

# If the above RewriteCond succeeded, we don't have a cache, so rewrite to 
# the pages.php URI, otherwise we fall off the end and go with the
# cache/pages/4.html
RewriteRule ^cache/pages/([^/\.]+).html pages.php?p=$1 [NC,QSA,L]

Turning off MultiViews is crucial (if you have them enabled) as well.

Options -MultiViews

Otherwise the initial request (/pages/...) will get automatically converted to /pages.php before mod_rewrite kicks in. You can also just rename pages.php to something else (and update the last rewrite rule as well) to avoid the MultiViews conflict.

Edit: I initially included RewriteCond ... !-d but it is extraneous.
