Apache的mod_rewrite无法删除尾部斜杠 [英] Apache's mod_rewrite failing to remove trailing slash

问题描述

我有一个XAMPP Apache服务器，并添加了一个配置文件，以用斜杠重写URL并将其重定向到无斜杠的对应URL.

因此，像http://example.com/the-audio/这样的URL被重定向到http://example.com/the-audio.问题是，当目录名只有一个单词时，它将无法正常工作.

因此，http://example.com/audio/不会删除斜杠.这对我来说真的很奇怪，在这种情况下，检查该日志似乎好像该规则不匹配.

这是我的规则(文件中只有一个)

.htaccess

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)\/+$
RewriteRule ^ %1 [R=301,L]

这是错误转储

提前谢谢！

解决方案

根据您的日志，/audio/是一个现有目录.因此，您的规则将不会运行，因为第一个条件会使其停止在现有目录上运行.删除第一个条件即可解决.

此外，要在现有目录上执行此操作，您将需要关闭DirectorySlash，否则服务器将在其自身中添加反斜杠.请注意，存在与此相关的一些安全问题.

I have a XAMPP Apache server, and have added a configuration file to rewrite URLs with a trailing slash and redirect to their slash-less counterparts.

Therefore, a url like http://example.com/the-audio/ gets redirected to http://example.com/the-audio. The problem is, it's not working when the directory name is only one word.

So, http://example.com/audio/ does not get it's slash removed. This is really strange for me, and checking the logs it appears as though the rule isn't matched in this case.

Here's my rule (only one in the file)

.htaccess

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)\/+$
RewriteRule ^ %1 [R=301,L]

And this is the error dump

Thanks in advance!

解决方案

According to your log /audio/ is an existing directory. So your rule wouldn't run since the first condition stops it running on existing directories. Remove the first condition to resolve it.

Also, to do this on existing directories, you will need to turn DirectorySlash off, or the server will add the slash back in itself. Note that there is some security concern with that.
