php - How to get get parameters after CI framework rewrites routing???

Question

Using CI 3.1.2 version
I want to rewrite the URL http://waimao.test.com/web/ho... to http://waimao.test.com/goods/64 ,
Added the following rules under application/config/routes.php:
$route['goods/(:any)'] = '/web/home/product_detail/?pid=$1';
The controller can jump normally, but $_GET cannot get the value. What is the problem????

Answer 1

Why do we need to add a slash?
