图像URL htaccess的重写规则 [英] htaccess rewrite rule for image url

问题描述

我的网址： http://www.mywebsite.com/i/1Q2GmFuFdZ.jpg

我想重写规则，使得它去到文件 image.php？ID = 1Q2GmFuFdZ.jpg

I want to rewrite a rule that makes it go to the file image.php?id=1Q2GmFuFdZ.jpg

在我的PHP文件，我有这样的

In my PHP file, I have this

<?PHP
print_r($_GET);
?>

这是我在我的htaccess

This is what I have in my htaccess

RewriteEngine On
RewriteRule ([a-zA-Z0-9]+[\.]+[a-z]{3})$ image.php?id=$1

这是我得到的输出：

Array ( [id] => image.php )

我不知道我做错了。我不是正则表达式亲，但我知道的基本知识。

I am not sure what I am doing wrong. I'm no regex pro but I know the basics.

感谢

编辑： 忘了补充0-9在EX pression

Forgot to add 0-9 in expression

推荐答案

mod_rewrite规则的递归应用。下面是当您请求 1Q2GmFuFdZ.jpg 会发生什么：

mod_rewrite rules are applied recursively. Here is what happens when you request 1Q2GmFuFdZ.jpg:

• 1Q2GmFuFdZ.jpg 匹配模式，变为 image.php？ID = 1Q2GmFuFdZ.jpg
• 由于文件名已经改变，另一次迭代与所述重新编写的URL执行
• image.php 的匹配模式以及的并改写为 image.php ？ID = image.php
• 在文件名或目录并没有变化，所以没有进一步的迭代执行
• 最终结果：<？code> image.php ID = image.php

• 1Q2GmFuFdZ.jpg matches the pattern, becomes image.php?id=1Q2GmFuFdZ.jpg
• Since filename has changed, another iteration is performed with the re-written URL
• image.php matches the pattern as well and rewritten as image.php?id=image.php
• File name or directory did not change so no further iteration is performed
• End result: image.php?id=image.php

解决方法：添加此规则：

Solution: add this rule:

RewriteEngine On
RewriteRule image\.php$ - [L]
RewriteRule ([a-zA-Z0-9]+\.[a-z]{3})$ image.php?id=$1

第二条规则作为手制动。你需要调整规则＃3为好。

The second rule acts as a hand-brake. You need to tweak rule #3 as well.
