Tp5.1 login configuration method of whether to login public functions (complete login case)

2022-07-25 02:34:00 【51CTO】

After configuration , You don't need to add a function to check login for each controller

1、 stay \application\admin\controller Create Common.php

       
       namespace app\admin\controller;
       
use think\Controller;
       
use think\Request;
       
use think\Db;
       
class Common extends Controller
       
{   
       
// Check if you are logged in 
       
  public function _initialize()
       
  {
       
     if(!session('username')){
       
       $this->error(' Please log in first ！',url('/admin/login/index'));
       
     }
       
  } 
       
}

Be careful ：

The controller has been inherited here (class Common extends Controller), Other controls do not inherit controllers , And it's Common

2、 Other control documents , such as ： stay \application\admin\controller The files under the admin.php
