正则表达式匹配 --所有语言通用

 uri的校验 匹配 http://0.0.0.0:55

       nd = {}
        nd['uuid'] = uuid.encode('utf-8')
        res = re.match(r"(http://){1}([\d]{2,3}([.]{1}" +
            "[\d]{1,3}){3}[:]{1}[\d]{2,5}){1}", uri)
        if res == None:
            return http_client.BAD_REQUEST, {'error': 'uri illegal'}
        if 'gffgfgg' and 'ghrefgfg' not in body.keys():
            LOG.error('create failed with body paras error')
            return http_client.BAD_REQUEST, {'error': 'create error'}
        nd['dcId'] = body['dcId'].encode('utf-8')

变量匹配 小写字母打头  只包含字母和数字的 

            m1 = re.match(r"(^[a-z]){1}", bianliang)
            m2 = re.search(r"([^a-z0-9])+", bianliang)
            if m1 == None and  m2:
                return http_client.BAD_REQUEST, {'error': 'params bianliang illegal!'}

ipv6匹配
