Apache RewriteRule [L] 未得到尊重

【问题描述】：

在启用了 SEF 的 Joomla 网站中，我有关键字友好的 url，例如 /keyword/keyword。我需要重写所有以index.php开头的url，例如/index.php/keyword/keyword

我尝试在 Joomla 附带的核心 .htaccess 规则之后和之前添加条件 RewriteRule：

## Begin - Joomla! core SEF Section.
#
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
#
# If the requested path and file is not /index.php and the request
# has not already been internally rewritten to the index.php script
RewriteCond %{REQUEST_URI} !^/index\.php
# and the requested path and file doesn't directly match a physical file
RewriteCond %{REQUEST_FILENAME} !-f
# and the requested path and file doesn't directly match a physical folder
RewriteCond %{REQUEST_FILENAME} !-d
# internally rewrite the request to the index.php script
RewriteRule .* index.php [L]
#
## End - Joomla! core SEF Section.


#rewrite all urls starting with index.php

RewriteCond %{REQUEST_URI} ^/index.php
RewriteRule ^index.php(.*?)$ /$1 [R=302,L]

这是重写日志：

似乎第一次重写时的 [L] 被忽略，第二次重写无论如何都会执行。我该如何解决这个问题？

澄清我期望发生的事情：

http://test.com/index.php/keyword header redirect 301 -> http://test.com/keyword
http://test.com/keyword rewrite -> http://test.com/index.php/keyword

    【解决方案1】：

    L 仅结束当前规则 ant 导致 mod_rewrite 再次循环遍历您的 .htaccess。

    实际上，您需要的是重新排序规则以在重写之前保持重定向：

    ## Begin - Joomla! core SEF Section.

#rewrite all urls starting with index.php
RewriteCond %{THE_REQUEST} /index\.php [NC]
RewriteRule ^index\.php(.*)$ $1 [R=302,L]

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

# If the requested path and file is not /index.php and the request
# has not already been internally rewritten to the index.php script
RewriteCond %{REQUEST_URI} !^/index\.php
# and the requested path and file doesn't directly match a physical file
RewriteCond %{REQUEST_FILENAME} !-f
# and the requested path and file doesn't directly match a physical folder
RewriteCond %{REQUEST_FILENAME} !-d
# internally rewrite the request to the index.php script
RewriteRule .* index.php [L]
#
## End - Joomla! core SEF Section.

    请务必在清除浏览器缓存后对其进行测试。

    【讨论】：

    • 不幸的是，我得到了完全相同的结果。如果我在这里尝试我的规则，并删除 E=HTTP_AUTHORIZATION:%{HTTP:Authorization} 规则，那么它就可以工作。但是在我的本地测试系统中删除它并不能解决问题。
    • 那么您在浏览器中输入的 URL 是什么，您看到了什么错误？
    • 我正在输入 test.com/keyword/keyword 并被重定向到 test.com，这是不正确的。
    【解决方案2】：

    我建议您使用 ErrorDocument 而不是尝试将其与重写规则一起使用：

    ## Begin - Joomla! core SEF Section.
#
RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
ErrorDocument 404 /index.php

    【讨论】：

    • 我不是在寻找错误文档。我正在寻找一种解决方案，允许我重定向test.com/index.php/keyword/keyword 而不会影响其他任何东西。
    • 我对你在这个问题中提到的不同网址感到困惑：在一条评论中你说你想重定向 example.com/keyword/keyword，在这里你说你想重定向 example.com/ index.php/关键字/关键字。人们在浏览器中输入的实际网址是什么？那应该在内部重定向到 index.php 脚本？
