.htaccess删除网址的重复部分 [英] .htaccess remove duplicate part of a URL

问题描述

我的在线目录SEF URL生成中的一些错误造成了以下情况:将某些类别的标签两次添加到URL.要解决此问题，我想使用.htaccess删除URL的这一部分，并使整个URL向上移动一个级别，包括URL，该URL下还包括一个产品.

some bug in my online catalog SEF URL generation created a situation where some category slug is added to the URL twice. to fix this i would like to use .htaccess to remove the this part of the URL and have the whole URL shift up one level including URL's which also include a product under them.

重复出现的是类别 tools

所以错误的URL看起来像这样:/store/items/catalog/tools/painting-tools/painting-tools或者/store/items/catalog/tools/painting-tools/painting-tools/{某些产品}

so the wrong URL looks like this: /store/items/catalog/tools/painting-tools/painting-tools or /store/items/catalog/tools/painting-tools/painting-tools/{some product}

不是这样的正确网址:

 /store/items/catalog/tools/painting-tools

或/store/items/catalog/tools/painting-tools/{某些产品}

or /store/items/catalog/tools/painting-tools/{some product}

和网址

  /store/items/catalog/tools/painting-tools/

或/store/items/catalog/tools/painting-tools/{某些产品}

or /store/items/catalog/tools/painting-tools/{some product}

实际上应该是这样

  /store/items/catalog/tools

或/store/items/catalog/tools/{某些产品}

or /store/items/catalog/tools/{some product}

尝试使用此规则，但不起作用

tried using this rule, but its not working

RewriteRule ^/painting-tools/painting-tools/(.*) /painting-tools/$1 [QSA]

我认为^部分不正确，因为它不是URL的开头.我该如何解决?谢谢

i think the ^ part is not correct since its not the beginning of the URL. How can i fix it ? thanks

推荐答案

您可以在.htaccess中将此基于反向引用的重定向规则用作第一条规则:

You can use this back-reference based redirect rule as very first rule in your .htaccess:

RewriteRule ^(.+?/([^/]+))/\2(/.*)?$ $1/$3 [NE,L,R=302]

RewriteRule ^(.+?/tools)/painting-tools(?:/.*)?$ $1/ [L,NC,R=302]

正在捕获初始部分之后的重复值，并将其分组到此子模式([^/] +)中.稍后在正则表达式中，它使用向后引用 \ 2 来确保重复捕获相同的值.

It is capturing repeat value after initial part and grouping it in this sub-pattern ([^/]+). Later in the regex it is using back-reference \2 to make sure same captured value is repeated.

确保您已正确定义/或/store/的htaccess所在的正确的 RewriteBase .

Make sure you have proper RewriteBase defined to either / or /store/ wherever your htaccess is located.

更新:根据以下讨论:

RewriteRule ^(.+?/tools)/painting-tools2(/.*)?$ $1$2 [L,NC,R=302]

这将从网址中删除/painting-tools2 .
