Apache重写意外地解析了两次URL

时间：2012-03-08 14:07:01

标签： apache .htaccess mod-rewrite

我正在尝试将所有网页从某些域名重定向到处理多个网站的特定网络应用程序。 我将我的网络应用程序放在“skylight2”文件夹和另一个名为“testsite”的文件夹中，只有一个.htaccess文件：

RewriteEngine on
RewriteRule ^(((?!skylight2).)*)$ /home/stefano/webroot_aliases/skylight2/$1/?site=testsite [QSA]

我正在使用虚拟根，我的httpd-vroot.conf看起来像这样：

<VirtualHost *:80>
        ServerName webserver
        ServerAlias *.webserver

        UseCanonicalName Off
        VirtualDocumentRoot /home/stefano/webroot_aliases/%1

        Options -Indexes FollowSymLinks -MultiViews
        RewriteLog "/var/log/httpd/vroot_rewrite.log"
        RewriteLogLevel 3

        <Directory /home/stefano/webroot_aliases/>
                Order allow,deny
                Allow from all
                AllowOverride FileInfo Indexes Limit Options

                RewriteEngine On
                RewriteBase / 
        </Directory>
</VirtualHost>

如果我尝试访问testsite.webserver，则会收到“找不到对象”错误。这是我的重写日志：

显然，URL被解析一次（正确），然后第二次再次添加前缀，导致错误。不幸的是，我不能在此规则中加上[L]标志，因为URL会在应用程序文件夹中进一步解析。 任何人都可以向我解释发生了什么事吗？

编辑：我应用了规则：

RewriteRule ^(?!skylight2)(.*)$ skylight2/$1/?site=testsite [QSA,L]

为什么apache会不断添加路径信息？ L和DPI标志都不起作用。

根据TerryE的建议，我使用了这个配置：

RewriteEngine On
RewriteBase /testsite
RewriteRule ^(?!skylight2)(.*)$ /skylight2/$1?site=testsite [QSA,L]

Apache抛出“文件不存在：/ home / stefano / webroot_aliases / testsite / skylight2”错误。正确的URL应该是/ home / stefano / webroot_aliases / skylight2 / articles / view。

可能是因为VirtualDocumentRoot设置为testsite并且一旦设置我就无法摆脱它吗？

顺便说一下，我正在使用Apache 2.2.22。

编辑＃3

我实际上通过在testsite中放置一个符号链接“skylight2”来解决它，指向“../skylight2”。谢谢你的帮助！

1 个答案:

答案 0 :(得分：2)

我之前遇到过这个错误，并且它上面有一个旧的bugrep，它已经失败了。如果您在Per Directory上下文中执行此操作，则可能会发生此问题。但是由于重写引擎无论如何都会循环遍历htaccess文件，[L]并不代表最后它真正意味着“重启循环”。

接下来您的重写规则是错误的，因为您的文档根目录是home / stefano / webroot_aliases，而规则目标位于URI空间而不是文件空间中，因此您的目标应该只是skylight2/$1/?site=testsite。

接下来，Negative lookahead断言不应该在（。*）循环中，所以请尝试：

RewriteRule ^(?!skylight2)(.*)$ skylight2/$1/?site=testsite [QSA,L]

如果这不起作用，则附加新的rewrite.log提取。感谢。

更新以下评论

重写日志显示DOCROOT为/home/stefano/webroot_aliases/testsite并重定向

articles/view -> testsite/skylight2/articles/view/?site=testsite

这使得负向前瞻和循环再次失败，所以当你做需要领先/替换字符串时就是这种情况：

RewriteBase  /testsite
RewriteRule ^(?!skylight2)(.*)$ /skylight2/$1/?site=testsite [QSA,L]
