thinkphp still has a problem with jumping to the pre-login page after logging in

I previously wanted to implement this in the background. Yesterday I asked a question about the link description here, but no one answered. I felt that the background implementation was a bit complicated. Then I wanted to implement the function of jumping after login in the front desk.
I am in the login template I made the following judgment. If there is a session, let it return to the previous page. When judging whether there is a session in the action, I only wrote that there is no session and then let it display() if there is no session. If there is, it will not be processed. I am just afraid. I can't jump to the previous page, so I didn't write it, but it still can't jump. I never thought that the problem of login jump is so complicated. I don't know if you guys have a good way. I searched all over the Internet and there is no good and complete example. Can everyone help me

<code><if condition="isset(session('res2')[0])">
<script type="text/javascript">
window.location=history.go(-1);
</script>
</if>
</code>
<code>public function login(){
            $user=M('user');
            $name=I('name');
            $pw=I('pw');
            $res=$user->where("username='$name' AND password='$pw'")->select();
            if($res){
               session('res2',$res);
            }
            if(!isset(session('res2')[0])){
               $this->display();//如果没有session则显示login页面 
            }      
    }</code>

<code>$_SERVER['HTTP_REFFERER']</code>

Just try history.go(-1)

Let’s put it this way, the problem of detecting login and permissions should be written in the parent class, and then let each controller inherit it.
Then judge
session(!$args)
Then redirct is roughly like this
As for the jump, you can read more about this self document, it should not be difficult.
Or you can also use session. thinkphp still has a problem with jumping to the pre-login page after logging in
