【中文标题】更多关于我可怜的 mod_rewrite 尝试的眼球请【英文标题】：More Eyeballs on my Poor mod_rewrite Attempt Please 【发布时间】：2011-04-07 15:58:58 【问题描述】：我们正在改变用户在其博客中嵌入图片的方式，但我需要确保之前嵌入的图片仍能显示。
我正在尝试将旧图像嵌入链接重定向到静态图像或单个旧图像嵌入处理文件。我正在使用 mod_rewrite，但似乎我失败了。令人惊讶的是，我设法拼凑出一个防止盗链的功能性规则集。
不过，我在将遗留嵌入重定向到单个遗留处理程序时遇到了一些困难。此规则属于热链接集[L]，因此只有在嵌入请求不是热链接的结果时才应评估。
这是我尝试将所有请求重定向到任何文件，例如gp[2]?.php[5]?\?p=(.*)
RewriteRule %REQUEST_FILENAME gp[2]?\.php[5]?(.*)=(.*)$ [NC]
RewriteRule gp[2]?\.php[5]?(.*)=(.*)$ /legacy/gp.php5$1=$2 [L]
但它不起作用，我只是得到了我美妙的 404 页面。
一些示例请求：
http://ecpod.com/includes/gp.php5?p=cfcfbfbe5d9d63eab4a3e784bd30cfe016fcfcfbfbe5d9d6a19ebc57139d56bb
http://www.ecpod.com/includes/gp.php5?p=928e3888a526b462b684aea5609016f928e3888a585d0963ac4ebb335a522e09
http://www.ecpod.com/includes/gp2.php?p=cfcfbfbe5d9d63eab4a3e784bd30cfe016fcfcfbfbe5d9d6a19ebc57139d56bb
我的目标是将任何看起来像这些示例之一的请求定向到：
http://ecpod.com/legacy/gp.php?p=HASH
感谢您的帮助。
编辑：
旧版网址将具有gp|gp2、php|php5 和长度为 n 的查询字符串。它们可能不一定在includes 目录中。我知道，这很混乱而且很可怕。现在图像嵌入的处理方式不同了，这种情况再也不会发生了。

【问题讨论】：
只是猜测ewriteRule 是一个 opy & aste 错误？ :)
【参考方案1】：
RewriteRule 测试模式的输入将不包含查询字符串，因此对其进行测试将阻止规则匹配和应用。
考虑到这一点，我们可以将规则改写成这样：
RewriteRule ^(includes/)?gp2?\.php5?$ /legacy/gp.php5 [NC,L]
假设查询字符串已经是您想要的格式，我们可以让mod_rewrite 自动附加它，而不是在我们的重写中指定替换。
如果您不确定查询字符串是否始终只是 p=HASH，并且希望保证它是针对目标脚本的，我们可以扩展规则块以考虑到这一点，寻找 @查询字符串中的 987654328@ 参数，并将现有查询字符串替换为该部分：
RewriteCond %QUERY_STRING (^|&)(p=[^&]+)(&|$) [NC]
RewriteRule ^(includes/)?gp2?\.php5?$ /legacy/gp.php5?%2 [NC,L]
根据Roland Illig's 的评论，您还可以执行以下操作以减少对文件所在目录的限制：
RewriteCond %REQUEST_URI !^/legacy/
# Input to RewriteRule in .htaccess never has a leading slash, so make sure
# we're at the beginning or there was a slash before the filename
RewriteRule (^|/)gp2?\.php5?$ /legacy/gp.php5 [NC,L]
编辑：更改了规则以反映它们在httpd.conf 而不是.htaccess 中的定义方式。编辑：...然后更改它又回来了。
【讨论】：
我建议改为RewriteRule /gp2?\.php5?$ /legacy/gp.php?%2 [NC,L]。它更短，不需要特定的目录，并确保 php5? 出现在 URI 的最后。
@Roland Illig - 哎呀，我忘记了结尾锚。我还删除了不必要的字符类。如果我们只是在最后锚定，我们需要一个额外的RewriteCond 到prevent an internal redirect loop，因为测试模式匹配我们重写的内容。不过，根据具体情况，这可能不是一个坏主意，所以我将其添加为另一种选择。
谢谢蒂姆，我都试过了，但这个 ecpod.com/includes/… 仍然给出 404。
@Michael Robinson - 当我点击链接时，我看到了一张图片，上面写着“ECPod 分享你的世界”，那么你刚刚让它工作了吗？
糟糕，我发现我弄错了。文档清楚地表明重写规则的替换是替换与 Pattern 匹配的原始 URL 路径的字符串。所以你应该尝试RewriteRule (?:^|.*/)gp2?\.php5?$ /legacy/gp.php [NC,L]。我不知道这是否适用于.htaccess 文件。【参考方案2】：
应该这样做：
RewriteRule ^\/includes\/gp\.php5?\?p=([a-f,0-9]64)$ /legacy/gp.php?p=$1
【讨论】：
嗯，我试过了，但不幸的是它不起作用.. 旧 url 可以是php 或 php5，并且文件可能不在 includes 目录中...应该在问题中说对不起。
RewriteRule ^\/(includes\/)?gp\.php5?\?p=([a-f,0-9]64)$ /legacy/gp.php?p=$2 这使得 include/ 目录是可选的，而 php5 中 5 之后的问号使得该字符是可选的。单独使用没有和 [] 修饰符的重写。它应该可以工作（我没有地方真正测试它）以上是关于更多关于我可怜的 mod_rewrite 尝试的眼球请的主要内容，如果未能解决你的问题，请参考以下文章
