liliuwei / thinkphp-auth example snippets

//简单实例
namespace app\admin\controller;
use think\Controller;

class Base extends Controller
{
    public function initialize()
    {
        if (!session('admin_id')) {
           $this->redirect('login/index');
        }
        $auth = new \liliuwei\think\Auth();
        $controller = strtolower(request()->controller());
        $action = strtolower(request()->action());
        $url = $controller . "/" . $action;
        if (!$auth->check($url, session('admin_id'))) {
           $this->error('抱歉，您没有操作权限');
        }
    }

//高级实例  根据用户积分判断权限

//Auth类还可以按用户属性进行判断权限， 比如 按照用户积分进行判断，假设我们的用户表 (tp_admin) 有字段 score 记录了用户积分。我在规则表添加规则时，定义规则表的condition 字段，condition字段是规则条件，默认为空 表示没有附加条件，用户组中只有规则 就通过认证。如果定义了 condition字段，用户组中有规则不一定能通过认证，程序还会判断是否满足附加条件。 比如我们添加几条规则：

//name字段：grade1 condition字段：{score}<100 
//name字段：grade2 condition字段：{score}>100 and {score}<200
//name字段：grade3 condition字段：{score}>200 and {score}<300

//这里 {score} 表示 think_members 表 中字段 score 的值。

//那么这时候

$auth = new \liliuwei\think\Auth();
$auth->check('grade1', 1); //是判断用户积分是不是0-100
$auth->check('grade2', 1); //判断用户积分是不是在100-200
$auth->check('grade3', 1); //判断用户积分是不是在200-300
