以下代码采用laravel框架，如果原生php自行改动

###同步请求

            'partner' => config('services.alipay.id'),
            'key' => config('services.alipay.key'),
            'sign_type' => strtoupper('MD5'),
            'input_charset' => strtolower('utf-8'),
            'cacert' => getcwd() . '\\cacert.pem',
            'transport' => 'http',
        ];
        $alipayNotify = new \AlipayNotify($alipayConfig);
        $result = $alipayNotify->verifyNotify();
        if ($result) {
            //更新订单状态
            return 'success';
        }

        return 'fail';
    }
