It's ok,now, I review HTTP_SERVICE sample.to call session->close in lambda.

            void POST(const std::shared_ptr<restbed::Session> session)
            {
                const auto request = session->get_request();
                long long int content_length = stoll(request->get_header("Content-Length", "0"));
                auto handler = [](const std::shared_ptr<restbed::Session> session, const restbed::Bytes &body) -> void
                {
                    string m_body(body.begin(), body.end());
                    colnago::dao::Post postObj;
                    postObj.parse(string(body.begin(), body.end()));
                    std::pair<bool, std::string> res = colnago::server::server.postDao->INSERT(postObj);
                    BaseResponse<> response(res.first, res.second);
                    session->close(restbed::OK, response.stringify(), {{"Content-Type", "application/json"}});
                };
                session->fetch(content_length, handler);
            }
