Description:

依赖注入对象失败。

可能原因：注入类的成员函数中使用了匿名类继承了另外一个类。导致在抽象语法树AST解析的时候误认为此类有父类，导致注入失败。错误信息大概的意思是这个类没有父类，不能使用parent关键字。

抛出的异常：

[ERROR] Cannot use "parent" when current class scope has no parent[20] in /www/runtime/container/proxy/XXX.proxy.php
[ERROR] #0 /www/vendor/hyperf/di/src/Resolver/ObjectResolver.php(99): App\Wx\Service\XXX->__construct()

Steps To Reproduce:

• 创建一个类，类中成员函数使用了匿名类继承了另外一个类

class Service{
    public function payNotify(RequestInterface $request, ResponseInterface $response){
        $payNotify = new class extends \Yurun\PaySDK\Weixin\Notify\Pay
        {
            /**
             * 后续执行操作
             * @return void
             */
            protected function __exec()
            {
                //var_dump($this->swooleRequest->getQueryParams());
                //var_dump($this->swooleRequest->post);
            }
        };
        //..........................................
       //..........................................
    }
}

• 在其他类中注入Service类时发生了错误（错误信息上面有）

namespace App\XXX\Controller;


use Hyperf\Di\Annotation\Inject;
class XXX extends AbstractController
{
    /**
     * @Inject
     * @var Service
     */
    private $service;
//...................................................
}

• Runtime中的Service代理类(AST生成),发现这个类没有父类，但是使用parent关键字

class VipService
{
    use \Hyperf\Di\Aop\ProxyTrait;
    use \Hyperf\Di\Aop\PropertyHandlerTrait;
    function __construct()
    {
        if (method_exists(parent::class, '__construct')) {
            parent::__construct(...func_get_args());
        }
        self::__handlePropertyHandler(__CLASS__);
    }
//.........................................
//.........................................
//.........................................
}

• 解决办法1：
  既然是没有父类导致的，那么继承一个父类就好了，比如BaseServcie类
• 导致错误的其它方式：
  （1）在一个文件中定义多个类，并且其中含有一个类有父类
• 根本原因：
  抽象语法树AST没有正确的判断这个类是否有父类

这个 VipService 就是内部有 匿名类 的 Service ？？？

[guiqibusixin]

是的哈，vipService就是前面所说的Service。这里忘记改名字了

按照 PR 里的修改，试试看

好。晚点试下
