问题描述

我正在尝试创建一个重写规则，该规则将仅检测数字并相应地转发它们.我希望重写规则可以忽略，除非出现数字.

I am trying to create a rewrite rule which will detect numbers only and forward them accordingly. I want the rewrite rule to be ignored if anything but numbers appears.

/index.php-确定
/-确定
/42365-重写为view.php?id=42365

/index.php - OK
/ - OK
/42365 - rewrites to view.php?id=42365

到目前为止我所拥有的:

What I have so far:

RewriteEngine on
RewriteRule ^([0-9]+)?$ view.php?id=$1 [L]

推荐答案

从([0-9]+)组的末尾删除?，这使其成为可选项.您必须必须有数字才能进行重写:

Remove the ? from the end of the ([0-9]+) group, which makes it optional. You must have numbers for the rewrite to occur:

RewriteEngine on
RewriteRule ^([0-9]+)$ view.php?id=$1 [L]
