为什么 Apache mod_rewrite 重写了两次我的 URL? [英] Why Apache mod_rewrite rewrites twice my URL?

问题描述

我需要将/admin/page/create URL重写为/backend/www/index.php/page/create，所以我使用了下一个Apache重写规则和条件:

RewriteCond %{REQUEST_URI} !-fRewriteCond %{REQUEST_URI} !-dRewriteCond %{REQUEST_URI} !backend\/wwwRewriteRule admin\/(.*)$ backend/www/index.php/$1 [NS,L]

然而，检查重写日志，我看到 Apache 正确地重写了 URL，但最后考虑到不匹配任何条件的 /page/create URL，它执行了额外的重写，所以它失败了，我收到 未指定输入文件." 错误.

如何阻止 Apache 执行额外的重写?我使用了 NS 标志和 RewriteCond %{IS_SUBREQ} f 条件，它也执行子请求.

谢谢！

解决方案

好吧，我终于使用变通方法解决了这个问题.首先我尝试了这些解决方案，但是子请求一次又一次地执行，重写和以前一样失败.

使用 mod_rewrite，如果您将规则放在 .htaccess 或全局配置(httpd.conf、Virtualhost 配置等)中，则存在细微差别.子请求是差异之一.只需将我上面提到的相同规则放在 Virtualhost 配置文件中，而不是 .htaccess 和子查询停止，一切都开始像魅力一样工作.

我推荐这篇有用的帖子，以便在尝试解决任何相关问题之前充分了解 mod_rewrite 的内部原理:http://net.tutsplus.com/tutorials/other/a-deeper-look-at-mod_rewrite-for-apache/

I need to rewrite /admin/page/create URL to /backend/www/index.php/page/create, so I use the next Apache rewrite rule and conditions:

RewriteCond %{REQUEST_URI} !-f
RewriteCond %{REQUEST_URI} !-d
RewriteCond %{REQUEST_URI} !backend\/www

RewriteRule admin\/(.*)$ backend/www/index.php/$1 [NS,L]

However, examining the rewrite log, I see Apache rewrites correctly the URL, but at the end it performs an additional rewrite considering /page/create URL, which doesn't match any condition, so it fails and I receive the "No input file specified." error.

How can I prevent Apache to perform that additional rewrite? I used NS flag and RewriteCond %{IS_SUBREQ} f condition and it also performs the subrequest.

Thank you!

解决方案

Well, I finally solved this issue using a workaround. First I tried these solutions, but subrequests were performed again and again and rewriting failed as before.

With mod_rewrite, there are small differences if you put a rule in .htaccess or in global configuration (httpd.conf, Virtualhost configuration, etc.). Subrequests are one of that differences. Just place the same rule I mentioned above in Virtualhost config file instead of .htaccess and subqueries stop and everything starts working like a charm.

I recommend this useful post to fully understand the internals of mod_rewrite before trying to solve any related to it issue: http://net.tutsplus.com/tutorials/other/a-deeper-look-at-mod_rewrite-for-apache/
