如何在.htaccess中更改我的网站网址结构

My current page-url looks like the below,

http://localhost/testWP/?mode=home

but I want to make the url like the following:

http://localhost/testWP/mode/home

• How do I write an appropriate .htaccess-file to turn this into reality?

Try adding these rules to your document root:

RewriteEngine On

RewriteCond %{THE_REQUEST} \ /+testWP/?\?mode=([^&\ ]+)
RewriteRule ^ /testWP/mode/%1? [L,R]

RewriteRule ^testWP/mode/(.+)$ /testWP/?mode=$1 [L]

Note that if you change your URL base (in your question it seems to be /testWP/), you'll need to adjust the rules to reflect any changes you make by replacing testWP with whatever is appropriate.
