if (at_resp_parse_line_args_by_kw()函数解析AT接受的地址出错？

我无法用换行识别获取，所以我利用关键字匹配来获取地址，函数如下
static void ec200x_get_netdev_info(struct rt_work *work, void *work_data)
{
#define AT_ADDR_LEN 32
#define EC200X_INFO_RESP_SIZE 128
    at_response_t resp = RT_NULL;
    char ip[AT_ADDR_LEN] = {0};
    char gateway[AT_ADDR_LEN] = {0};
    char netmask[AT_ADDR_LEN] = {0};
    char dns[AT_ADDR_LEN] = {0};
    char mac[AT_ADDR_LEN] = {0};
    ip_addr_t ip_addr;
    rt_uint32_t mac_addr[6] = {0};
    rt_uint32_t num = 0;
    // rt_uint32_t dhcp_stat = 0;
    // char dns_server1[AT_ADDR_LEN] = {0}, dns_server2[AT_ADDR_LEN] = {0};
    struct at_device *device = (struct at_device *)work_data;
    struct netdev *netdev = device->netdev;
    struct at_client *client = device->client;
    rt_err_t result = RT_EOK;
    int retry_num = 3;
    if (work != RT_NULL)
    {
        rt_free(work);
    }
    resp = at_create_resp(EC200X_INFO_RESP_SIZE, 2, rt_tick_from_millisecond(1000));
    if (resp == RT_NULL)
    {
        LOG_E("no memory for resp create.");
        goto __exit;
    }
while (retry_num--)
    {
        at_obj_exec_cmd(device->client, resp, "AT+QGETIP=station");
        if (at_resp_parse_line_args_by_kw(resp, "+QGETIP:","+QGETIP:ip:%[^\"],gate:%[^\"],mask:%[^\"],dns:%[^\"],%*s",
        ip, gateway, netmask, dns) <= 0)
        {
            at_resp_parse_line_args_by_kw(resp,"+QGETIP:","+QGETIP:gate:%[^\"],%*s",gateway);
            at_resp_parse_line_args_by_kw(resp,"+QGETIP:","+QGETIP:ip:%[^\"],%*s",ip);
            continue;
        }
        else
        {
            break;
        }
    }
    if (retry_num < 0)
    {
        goto __exit;
    }
LOG_D("%s device primary ip address: %s", device->name, ip);
LOG_D("%s device primary gate address: %s", device->name, gateway);
    inet_aton(ip, &ip_addr);
    netdev_low_level_set_ipaddr(netdev, &ip_addr);
    at_netif_refresh(&ip_addr, RT_NULL, RT_NULL); // 网卡写入IP地址
    /* set netdev info */
    inet_aton(gateway, &ip_addr);
    netdev_low_level_set_gw(netdev, &ip_addr);
    at_netif_refresh(RT_NULL, RT_NULL, &ip_addr); // 网卡写入网关
    inet_aton(netmask, &ip_addr);
    netdev_low_level_set_netmask(netdev, &ip_addr);
    at_netif_refresh(RT_NULL, &ip_addr, RT_NULL); // 网卡写入子网掩码
    inet_aton(dns, &ip_addr);
    netdev_low_level_set_netmask(netdev, &ip_addr);
    at_netif_refresh(RT_NULL, &ip_addr, RT_NULL); // 网卡写入dns地址
netdev_low_level_set_dhcp_status(netdev, RT_TRUE);
    result = RT_EOK; // yuanyuan加入
__exit:
    if (resp)
    {
        at_delete_resp(resp);
    }
}
获取地址语句为：
if (at_resp_parse_line_args_by_kw(resp, "+QGETIP:","+QGETIP:ip:%[^\"],gate:%[^\"],mask:%[^\"],dns:%[^\"],%*s", ip, gateway, netmask, dns) <= 0)
但最终的结果为：用了%*s，但，后面的回显还是没有屏蔽掉，并且所有的地址全部赋值给了IP

我想问一下，这样的地址要怎么获取，只能通过区字符串吗？
