注册回调事件验证失败

hi，版本是：php7.3.5 ,会提示{"errcode":71009,"errmsg":"返回文本非succes}，询问钉钉官方，说是不支持7.1+版本 ,验证回调的写法如下，不知道有没有遇到过这个问题

    $signature = $_GET["signature"];
    $timeStamp = $_GET["timestamp"];
    $nonce = $_GET["nonce"];
    $postdata = file_get_contents("php://input");
    $postList = json_decode($postdata,true);
    $encrypt = $postList['encrypt'];
    $crypt = new DingtalkCrypt(TOKEN, ENCODING_AES_KEY, SUITE_KEY);
    $msg = "";
    $res = $crypt->DecryptMsg($signature, $timeStamp, $nonce, $encrypt, $msg);

    if ($res['ErrorCode'] != 0){//当解密失败记录
        Log::e("ErrorCode:" . $res['ErrorCode']);
        Log::e(json_encode($_GET));
        Log::e(json_encode($encrypt));
        Log::e('------------------------------------------------------------------------------------------');
    }else{
        Log::e("SuccessCode:" . $res['ErrorCode']);
        if(!$res['data']){//当返回值为空记录加密字符串信息
            Log::e(json_encode($_GET));
            Log::e(json_encode($encrypt));
        }
        Log::e(json_encode($res['data']));
        Log::e('------------------------------------------------------------------------------------------');

        //创建成功后的回调推送
        //$eventMsg = json_decode($res['data']);
        //$eventType = $eventMsg->EventType;

        //工作流变动:审批任务开始，结束，转交
        //if("bpms_task_change" === $eventType){

        //}

        //工作流变动:审批实例开始，结束
        //if("bpms_instance_change" === $eventType){

        //}
        //注册回调接口 回调URL返回值调试
        $res = "success";
        $encryptMsg = "";
        $encryData = $crypt->EncryptMsg($res, $timeStamp, $nonce, $encryptMsg);
        if($encryData['ErrorCode'] != 0){
            Log::e("ERR:" . $encryData);
        }else{
            echo $encryData['data'];
        }

    }
