03、查询路由以及路由的外部网关信息

直接上代码

//获取连接
OSClientV3 os=getOSClientV3(tenantid,user_id,password,region);
//获取网络服务
NetworkingService ns = os.networking();
//获取路由
List routerList = ns.router().list();
//遍历路由
if(routerList != null){
            for(Router r : routerList){
                 //通过网卡查询外部网关
                    ExternalGateway eg = r.getExternalGatewayInfo();
                    //根据路由ID查询网卡信息
                    PortListOptions plo = PortListOptions.create();
                    plo.deviceId(r.getId());
                    String netWorkid = eg.getNetworkId();
                    plo.networkId(netWorkid);
                    //使用此网卡的实体类型
                    plo.deviceOwner("network:router_gateway");
                    List portList = ns.port().list(plo);
                    ---todo,遍历即可获取外部网卡信息
                }
