Laravel:拆分URL

I have the following url :

http://PenTest.dev/store?user_id=1

Basically this opens a pop via JavaScript.

The operations/logic is in a function and at the ends i am redirecting like this,

return redirect()->back()

Which again returns to the old url,

What i want is to redirect PenTest.dev/store

Is there any way to redirect to the above url.

see this Redirects in the docs

return redirect()->route('login');
