在order.php 中能够获取到 $tgis->uid。

Fpe.php : 不能够获取到 $this->uid   ::

class Fpe extends Common
{

    public function __construct()
    {
         $this->businessAlliance = new BusinessFederationLogic();
         $this->validate = new BusinessAlliance();
    }

    public function typesOption()
    {
        if (!$this->uid) return resultArray(lang('NO_USER'), "", 102);
        $logic = new GroupLogic();
        return $logic->getTypesLists($this->uid, $this->Language);
    }

    public function submit()
    {
        if(request()->isPost()){
            $post = request()->post();
            $this->validate->scene('submit')->check($post);
            if ($this->validate->getError()) {
                return resultArray(lang(strval($this->validate->getError())));
            }
            dump($this->uid);
            dump('ssss');
            die();
            return $this->businessAlliance->submit($this->uid,$post['account'],$post['name'],$post['phone'],$post['province'],$post['city'],$post['zone'],$post['address'],$post['wechat'],$post['qq']);
        }
        return '';
    }

打印的结果：

解决办法 ：

在__construct 函数中  调用父 构造函数

public function __construct(App $app = null)
{
     parent::__construct($app);
     $this->businessAlliance = new BusinessFederationLogic();
     $this->validate = new BusinessAlliance();
}
