limodou,您好！

	应该没问题啊，后面还有加上这些代码啊：

	        response_ob = conn.getresponse()
            if response_ob.reason == 'OK':
                self.stc.svc_stat = 'OK'
                time_begin = time.time()
                page_len = len(response_ob.read())
                time_end = time.time()
                time_cost = time_cost + round(time_end - time_begin, 4)
                break
            else:
