修复 RewriteRule - 访问由连字符分隔的字符串末尾的 ID

问题描述

我有一个包含超过 3000 张图片的图片库，并且还在不断增加。我访问图像的网址如下：

1.
http://example.com/gallery/image/cloud-blue-plane-hawaii-428459

or 

2.
http://example.com/gallery/image/428459

PHP 脚本可以在这里找到：

http://example.com/gallery/image.PHP?image=428459

所以，我需要编写一个 RewriteRule 来访问它。

我相信第二个网址的正确规则（http://example.com/gallery/image/428459 ) 如下：

RewriteRule ^gallery/image/(\d+|[^/]+)/?$ gallery/image.PHP?image=$1 [L]

当需要为第一个 url ( http://example.com/gallery/image/cloud-blue-plane-hawaii-428459 ) 编写规则时，我有点不知所措……我不知道……

有没有办法为两个 url 制定一个规则？

解决方法

使用

^gallery/image/[^/]*?([0-9]+)/?$

见proof。

  (                        group and capture to \1:

--------------------------------------------------------------------------------
  )                        end of \1
--------------------------------------------------------------------------------
  /?                       '/' (optional (matching the most amount
                           possible))
--------------------------------------------------------------------------------
  $                        before an optional \n,and the end of the
                           string
