ThinkPHP's redirect jump and referer usage issues

If you jump from the Topic/topic page to the Login/login page using $_SERVER['HTTP_REFERER'] and then log in, the address of the page will be like this http://localhost/a/jz/index .php/Home/topic/topic, this address is correct, why does the address on the address bar become like this after I use redirect? http://localhost/a/jz/index.php/a/jz /index.php/Home/Login/login.html? And why is this jump address not the address previously stored in the session?

<code>以下是login控制器下login操作方法跳转部分的代码
$url=$_SERVER['HTTP_REFERER'];
session('url',$url);
var_dump(session('url'));
if(!isset(session('res2')[0])){  //验证通过产生的session是否存在
    $this->display();            //不存在session还显示login页面
}else{
    $this->redirect(session('url')); //存在则跳转
}</code>

It should be a problem handled by

$this->redirect

Method 1: Use

str_replace

to remove the previous part of the content obtained by $_SERVER['HTTP_REFERER']$url = str_replace('http://localhost/a/jz/index.php','' ,$url); Method 2: Instead of using

$this->redirect(session('url'));

jump, use header('location:'.session('url'));exit();
