namespace app\admin\controller;

class Index

{

use \traits\controller\jump;

public function index()

{

return 'HELLow';

}

public function test($name)

{

if($name=='php')

{

$this->success('Jumping','//m.sbmmt.com');

}

}

}

This is my code. I have checked it several times and found no problem. I just need to use \traits\controller\ jump; you can run it after logging out, otherwise an error will be reported
