            if (!$responseStr) {
                throw new Exception("【".date("Y-m-d H:i:s")."】  参数不能为空\r\n");
            }

            $passed = IcbcSignature::verify($respBizContentStr, $responseArr['sign_type'], C("icbc_gateway_public_key"), $responseArr['charset'], $sign,'');
            if (!$passed) {

            }

            // 修改unipay_log

            return $this->response("-1","error");
        }
    }

    /**

    private function response($return_code,$return_msg) {
        // 应答
        $respBizContent = array(
            'return_code' => $return_code,
            'return_msg' => $return_msg,
            'msg_id' => microtime()
        );

        $answer['response_biz_content'] = json_encode($respBizContent);
        $answer['sign_type'] = C('icbc_sign_type');
        $answer['sign'] = IcbcSignature::sign(substr(json_encode($answer),1),C("icbc_sign_type"),C("icbc_private_key"),C("icbc_charset"),'');

        return json_encode($answer);
    }

强调：
在支付回调签名验证的时候的path不要自己手写，会发生验签不通过，切记要用

 $path = parse_url('域名' +'接口名', PHP_URL_PATH);
