htaccess从网址中删除特定的查询字符串

Question

I have the URL

http://example.com/index.php?err=true&i=1

The i value changes 1 to 3. I want to transform that URL into this:

http://example.com/index.php?err=true 

Whenever the query string parameter i is found in the URL, the i has to be removed from the URL.

Answer 1

You can use this rule to remove parameter i from the query string from any position:

RewriteEngine On

RewriteCond %{THE_REQUEST} \?(.*&)?i=[^&]*&?(\S*)\sHTTP [NC]
RewriteRule ^ %{REQUEST_URI}?%1%2 [R=308,NE,L]
