插件后台管理控制器

1. 在插件类主文件里加hasAdmin为1的属性；

2. 默认后台管理控制器AdminIndex,默认方法index,不可更改

3. cmf_get_current_admin_id();可获取后台管理员id，可用于判断是否登录

在插件controller目录下创建AdminIndexController.php文件,内容如下:

namespace plugins\demo\controller; //Demo插件英文名，改成你的插件英文就行了

use think\Db;
use cmf\controller\PluginBaseController;
use plugins\Demo\Model\PluginDemoModel;

class AdminIndexController extends PluginBaseController
{

    function _initialize()
    {
        $adminId = cmf_get_current_admin_id();//获取后台管理员id，可判断是否登录
        if (!empty($adminId)) {
            $this->assign("admin_id", $adminId);
        } else {
            //TODO no login
        }
    }

    function index()
    {
        $users = Db::name("user")->limit(0, 5)->select();
        $demos = PluginDemoModel::all();

        // print_r($demos);

        $this->assign("users", $users);

        return $this->fetch('/admin_index');
    }

}
