Laravel permission control

Add roles to the user table id, According to the character id Get user role , If it is a role, there is no need to create an intermediate table , Otherwise, you need to create an intermediate table .

According to the character id Get the role owned by the user , Get the permissions of the role according to the Chinese table of roles and permissions id, According to authority id Get the permission range of the user ,

$node_id = role_node::where('role_id', $role['id'])->get()->toArray();

  $res = [];
        foreach ($node_id as $v) {
            $res[] = node::where('id', $v['node_id'])->first()->toArray();

        }

What we got here $res It is the user permissions queried , Deposit in session in , Then read the current permissions of the user in the middleware ,

This is the user permission obtained

 

Read the user's permission in the display homepage , Use recursion or three-level linkage , What you read is before you get it and then put it in session Authority

  $res = Cache::get('auths');
        $rbac = rbac::data($res);
        return view('index', ['list' => $rbac]);

recursive ：

 public static function data($data,$pid=0)
        {
            $res=[];
            foreach ($data as $v){
                if ($v['pid']==$pid){
                    $res[$v['id']]=$v;
                    $res[$v['id']]['son']=self::data($data,$v['id']);
                }
            }
            return $res;
        }

Then display the obtained permissions on the home page .
