我有一个很难创建重写规则，使用旧的URL的一部分重定向。例如：

旧网址： HTTP：// WWW .example.com的/新闻/ index.php文件/一十一分之二千零一十四/ 07 /我 - 博客 - 后 - 从历史的现场 要么 http://www.example.com/news/index.php /十一分之二千〇一十四/ 07 / my_blog_post_from_old_site

新网址： http://www.example.com/2014/11/07/my -blog岗位

新的URL应该只具有日期和固定链接由破折号剥离后，前三个元素。即使我不知道是否可以使用的.htaccess规则作出规定，但肯定可以使用PHP来完成。

下面是我的.httaccess规则

 的RewriteCond％{HTTP_HOST} ^ example.com [NC，OR]
的RewriteCond％{HTTP_HOST} ^ www.example.com [NC]
重写规则^（/？新闻/ index.php文件/.*/[^/]*?)_([^/]*?_[^/]*)$ $ 1- $ 2 [N]
重写规则^（/？新闻/ index.php文件/.*/[^/]*?)_([^/_]*)$ $ 1- $ 2 [R = 301]
重写规则^新闻/ index.php文件/([^/]+)-([^/]+)-(.*)$ http://www.example.com/$1-$2-$3 [L，R = 301 ，NC]
 

解决方案

只是匹配块，直到连字符（ - ）遇到：

 重写规则^新闻/指数 .PHP /([^-]+-[^-]+-[^-]+).* / $ 1 [R = 301，L ，NC]
 

I have a hard time to create rewrite rule for a redirect using part of an old URL. Example:

Old URL: http://www.example.com/news/index.php/2014/11/07/my-blog-post-from-old-site or http://www.example.com/news/index.php/2014/11/07/my_blog_post_from_old_site

New URL: http://www.example.com/2014/11/07/my-blog-post

New URL should to have only dates and first three elements of a permalink after stripping from dashes. Even I'm not sure if can be done using .htaccess rule but for sure can be done using PHP.

Here are my .httaccess rules

RewriteCond %{HTTP_HOST} ^example.com [NC,OR]
RewriteCond %{HTTP_HOST} ^www.example.com [NC]
RewriteRule ^(/?news/index.php/.*/[^/]*?)_([^/]*?_[^/]*)$ $1-$2 [N]
RewriteRule ^(/?news/index.php/.*/[^/]*?)_([^/_]*)$ $1-$2 [R=301]
RewriteRule ^news/index.php/([^/]+)-([^/]+)-(.*)$ http://www.example.com/$1-$2-$3 [L,R=301,NC]

Just match for the blocks until hyphen (-) is encountered:

RewriteRule ^news/index.php/([^-]+-[^-]+-[^-]+).* /$1 [R=301,L,NC]
