我已经从Joomla导入了我的文章！到K2保持id相同。现在我想重写Joomla！指向K2项目的url。我使用的Joomla 2.5.9带有SEF和modrewrite功能。此外，我从未使用过modrewrite规则，我认为这是最好的选择，因为我有成千上万的文章。
我想更改的url为：
http://www.mysite.com/news/component/content/article/9-society/19771-the-alias-of-the-article
并且同一K2项目生成的url是
http://www.mysite.com/news/society/19771-the-alias-of-the-article
我创建了菜单项society以便获得此url。
因此，我编辑了.htaccess来创建一个规则，如下所示
RewriteRule ^news/component/content/article/9-(.*)$ /news/$1 [R=301,L]
但我得到了一个404错误页面。请注意，这个例子是为了了解modrewrite是否有效。我没有考虑id类别(本例中为9(。
问题是：重写规则遗漏了什么？
此外，我还尝试了我在SO中看到的其他规则，并在谷歌上搜索，试图了解它们是如何工作的，但也涉及404错误页面。就我所知，这个问题中提供的规则是应该发挥魔力的规则。
答案中建议修改的htaccess文件如下(我的网站在新闻文件夹中。如果我使用重写库，我需要调整它(：
##
# @package Joomla
# ...
Options +FollowSymlinks -MultiViews
## Mod_rewrite in use.
RewriteEngine On
## Begin - Rewrite rules to block out some common exploits.
# Block out any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]*([^)]*) [OR]
# Block out any script that includes a <script> tag in URL.
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
# Block out any script trying to set a PHP GLOBALS variable via URL.
RewriteCond %{QUERY_STRING} GLOBALS(=|[|%[0-9A-Z]{0,2}) [OR]
# Block out any script trying to modify a _REQUEST variable via URL.
RewriteCond %{QUERY_STRING} _REQUEST(=|[|%[0-9A-Z]{0,2})
# Return 403 Forbidden header and show the content of the root homepage
RewriteRule .* index.php [F]
#
## End - Rewrite rules to block out some common exploits.
## Begin - Custom redirects
# My site is in the news folder. If I use RewriteBase I need to adjust it
RewriteBase /news/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^news/component/content/article/9-([^/]+)/([^/]+)/? /news/$1/$2 [R=301,L]
## End - Custom redirects
##
# Uncomment following line if your webserver's URL
# is not directly related to physical file paths.
# Update Your Joomla! Directory (just / for root).
##
# RewriteBase /
## Begin - Joomla! core SEF Section.
#
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
#
# If the requested path and file is not /index.php and the request
# has not already been internally rewritten to the index.php script
RewriteCond %{REQUEST_URI} !^/index.php
# and the request is for something within the component folder,
# or for the site root, or for an extensionless URL, or the
# requested URL ends with one of the listed extensions
RewriteCond %{REQUEST_URI} /component/|(/[^.]*|.(php|html?|feed|pdf|vcf|raw))$ [NC]
# 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.
您可以在根目录中的一个.htaccess文件中尝试此操作
已为文件夹/news中的.htaccess文件更新：
Options +FollowSymlinks -MultiViews
RewriteEngine On
RewriteBase /news
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^component/content/article/9-([^/]+)/([^/]+)/? $1/$2 [R=301,L]
重定向
带或不带尾部斜线的http://www.mysite.com/news/component/content/article/9-society/19771-the-alias-of-the-article
至
http://www.mysite.com/news/society/19771-the-alias-of-the-article
除society和19771-the-alias-of-the-article外，所有字符串都假定为固定字符串。
对于静默映射，从[R=301,L] 中删除R=301
注：两个RewriteCond %{REQUEST_FILENAME}...都用于防止循环。他们检查文件或目录是否存在，如果存在则跳过规则。
