htaccess从网址中删除参数 [英] htaccess remove the parameter from url

问题描述

我正在尝试从网址中删除某些网址参数.这些参数对显示的内容不再有影响，但是google对其进行了索引.

I am trying to remove certain url parameters from the urls. Those parameters have no effect on the content being displayed anymore, but google have a bunch of them indexed.

我想将它们重定向到基本URL.
这是示例.

I would like to redirect them to the base url.
Here are the examples.

来自www.myexamplesite.com/?start=10
到:www.myexamplesite.com

From www.myexamplesite.com/?start=10
To: www.myexamplesite.com

来自www.myexamplesite.com/folder1/?start=10
到:www.myexamplesite.com/folder1

From www.myexamplesite.com/folder1/?start=10
To: www.myexamplesite.com/folder1

来自www.myexamplesite.com/folder2/?start=10
到:www.myexamplesite.com/folder2

From www.myexamplesite.com/folder2/?start=10
To: www.myexamplesite.com/folder2

实际上我不需要带有参数的url，所以我想知道是否可以找到一种方法来从url中捕获并重定向所有其他可能的参数，并且只允许我在htaccess中指定的一些选定参数.

Actually I don't need to have any urls with parameters, so I am wondering if there can be a way to catch and redirect all other possible parameters from the urls, and only allow some selected ones that I will specify in htaccess.

示例:
来自www.myexamplesite.com/?param1=10
到:www.myexamplesite.com

Examples:
From www.myexamplesite.com/?param1=10
To: www.myexamplesite.com

来自www.myexamplesite.com/?param1=10&param2=20
到:www.myexamplesite.com

From www.myexamplesite.com/?param1=10&param2=20
To: www.myexamplesite.com

来自www.myexamplesite.com/folder1/?param1=10
到:www.myexamplesite.com/folder1

From www.myexamplesite.com/folder1/?param1=10
To: www.myexamplesite.com/folder1

来自www.myexamplesite.com/folder1/?param1=10&param2=20
到:www.myexamplesite.com/folder1

From www.myexamplesite.com/folder1/?param1=10&param2=20
To: www.myexamplesite.com/folder1

但是对于param3，它应该是我选择的一个:

But for param3 which should be my selected one:

来自www.myexamplesite.com/folder1/?param3=10 保持原样:www.myexamplesite.com/folder1/?param3=10

更新
我实际上已经实现了一个解决方案，但是我的主要问题是它总是重定向到主页，而不是适当的REQUEST_URI ...

Update
I actually have already implemented a solution, but my main problem is that it always redirect to the home page and not the appropriate REQUEST_URI...

这是我所拥有的:

RewriteCond %{QUERY_STRING} .
RewriteCond %{QUERY_STRING} !^item= 
RewriteCond %{REQUEST_URI} !^/manage
RewriteRule .? http://www.myexamplesite.com%{REQUEST_URI}? [R=301,L] 

推荐答案

您可以使用此规则除去所有查询字符串，除非在其中找到param3=.

You can use this rule to strip all query strings except when param3= is found in it.

RewriteEngine On

RewriteCond %{QUERY_STRING} .
RewriteCond %{QUERY_STRING} !(?:^|&)param3= [NC]
RewriteRule ^ %{REQUEST_URI}? [R=301,L,NE]
