如何将除一个 URL 之外的所有 URL 重定向到脚本

发布于 2024-09-15 20:02:19 字数 361 浏览 10 评论 0原文

我试图让 www.example.com 和 www.example.com/index.html 转到 index.html，但我希望所有其他网址（例如 www.example.com/this/is/another/link）仍然显示 www.example.com/this/is/another/link 但由通用脚本处理。我已经尝试过

RewriteEngine on
RewriteCond %{REQUEST_URI} !^index\.html$
RewriteCond %{REQUEST_URI} !^$
RewriteRule ^(.*)$ mygenericscript.php [L]

，但行不通，有人可以帮忙吗？

I'm trying to get www.example.com and www.example.com/index.html to go to index.html, but I want all other urls e.g. www.example.com/this/is/another/link to still show www.example.com/this/is/another/link but be processed by a generic script. I've tried

RewriteEngine on
RewriteCond %{REQUEST_URI} !^index\.html$
RewriteCond %{REQUEST_URI} !^$
RewriteRule ^(.*)$ mygenericscript.php [L]

but it wont work, can someone please help?

您可以只测试资源是否存在，而不是测试 %{REQUEST_URI} 是什么：

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* mygenericscript.php

这可以防止您的静态资源（图像、样式表等）在通过您的 .htaccess 也位于同一目录中。

现在可能发生的情况是，当您尝试访问 / 或 /index.html.这是因为 .* 匹配每个请求，并且在您第一次重写到 mygenericscript.php 后，规则集将被重新处理（因为 mod_rewrite code> 在您使用它的上下文中工作）。

Instead of testing what %{REQUEST_URI} is, you can instead just test if the resource exists:

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* mygenericscript.php

This prevents your static resources (images, stylesheets, etc.) from being redirected if they're handled through the same directory your .htaccess is in as well.

What's probably happening now is that you're seeing an internal server error, caused by an infinite internal redirection loop when you try to access anything that isn't / or /index.html. This is because .* matches every request, and after you rewrite to mygenericscript.php the first time, the rule set is reprocessed (because of how mod_rewrite works in the context that you're using it in).

最简单的方法是安装一个 404 处理程序，当服务器找不到要显示的文件时执行该处理程序。

ErrorDocument 404 /mygenericscript.php

或

ErrorDocument 404 /cgi-bin/handler.cgi

类似的应该可以解决问题。

并不是说 RewriteRule 不能用于此目的，只是它们的设置比较棘手，并且需要深入了解 apache 如何处理请求。这有点像黑魔法。

The easiest to do this is to install a 404-handler which gets executed when the server does not find a file to display.

ErrorDocument 404 /mygenericscript.php

ErrorDocument 404 /cgi-bin/handler.cgi

or similar should do the trick.

It is not that RewriteRule's can not be used for this, it is just that they are tricky to set up and requires in depth knowledge on how apache handles requests. It is a bit of a black art.
