的.htaccess定期EX pression需要进行尾随正斜杠可选 [英] .htaccess regular expression need to make trailing forward slash optional

问题描述

我需要包括一个可选尾随forwardslash，这是一个/在我的重写规则

I need to include an optional trailing forwardslash, that's an /, in my RewriteRule

我至今是

RewriteRule ^([a-zA-Z0-9]+)$ u.php?$1|$2

//：

工作正常，例如 http://foo.bar/abcde 会重定向到的http://foo.bar/u.php?abcde 并处理任何查询字符串参数，这可能是present。

Which works fine, for example http://foo.bar/abcde will redirect to http://foo.bar/u.php?abcde and handles any querystring parameters that may be present.

我需要做的是采取 http://foo.bar/abcde/ （与尾随forwardslash），并重定向到 http://foo.bar/u.php?abcde

What I need to do is take http://foo.bar/abcde/ (with the trailing forwardslash) and redirect to http://foo.bar/u.php?abcde

因此​​，如果present，我需要删除从$ 1的最后斜线在我的重写规则。我该怎么做呢？我是新来的Apache和已经尝试了许多不同的正则表达式规则，但不能得到它的权利。

So, if its present, I need remove the final forward slash from $1 in my RewriteRule. How do I do this? I'm new to apache and have tried many different regex rules but can't get it right.

推荐答案

只要把 / <？/ code>在 $ 在结束在你的模式：

Just put /? before the $ at the end in your pattern:

RewriteRule ^([a-zA-Z0-9]+)/?$ u.php?$1

不过，我更建议你允许只有一个拼写（无论有或没有斜线）和重定向另一个：

But I would rather suggest you to allow just one spelling (either with or without trailing slash) and redirect the other one:

# remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*)/$ /$1 [L,R=301]
# add trailing slash
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .*[^/]$ /$0/ [L,R=301]
