htaccess：从查询字符串中删除选定的键=值对 [英] htaccess: remove selected key=value pair from query string

问题描述

我一直在努力解决这个问题，但是.htaccess的功能却不尽如人意。我有以下示例查询字符串：

I've been trying to work my head around this but my .htaccess powers just aren't as good as I thought. I have this sample query string:

http://mycoolsite.com/store.php?a=apples&type=fresh&b=banana

是否可以使用.htaccess来做到这一点：

Is it possible to do this using .htaccess:

1. 检查是否存在 type = fresh 。如果不是，则重定向到页面index.php


2. 如果存在 type = fresh ，请将其删除，但保留其余的查询字符串

1. Check if type=fresh exists. If not then redirect to page index.php
2. If type=fresh exists, remove it but retain the rest of the query string

推荐答案

您可以使用mod_rewrite来匹配查询字符串。在您的.htaccess文件中：

You can use mod_rewrite to match against the query string. In your .htaccess:

RewriteEngine On
RewriteCond %{QUERY_STRING} ^(.*)type=fresh&?(.*)$
RewriteRule ^(.*)$ /$1?%1%2   [L,R]

如果有人输入在浏览器中http://mycoolsite.com/store.php?a=apples&type=fresh&b=香蕉，他们的浏览器将重定向到 http://mycoolsite.com/store.php?a=apples&b=banana 。如果您希望重定向在内部进行（因此浏览器的位置栏不会改变），请删除RewriteRule末尾方括号中的，R 。

This will make it so if someone enters http://mycoolsite.com/store.php?a=apples&type=fresh&b=banana in the browser, their browser will get redirected to http://mycoolsite.com/store.php?a=apples&b=banana . If you want the redirect to happen internally (so the browser's location bar doesn't change), remove the ,R in the brackets at the end of the RewriteRule.
