测试场景:网关设备(IotProductDeviceTypeEnum 的 GATEWAY 类型)通过 UDP 协议管理子设备拓扑关系 * *

使用步骤: *

    *
  1. 启动 yudao-module-iot-gateway 服务(UDP 端口 8093)
  2. *
  3. 运行 {@link #testAuth()} 获取网关设备 token,将返回的 token 粘贴到 {@link #GATEWAY_TOKEN} 常量
  4. *
  5. 运行以下测试方法: * *
  6. *
* *

注意:UDP 协议是无状态的,每次请求需要在 params 中携带 token(与 HTTP 通过 Header 传递不同) * * @author 芋道源码 */ @Slf4j @Disabled public class IotGatewayDeviceUdpProtocolIntegrationTest { private static final String SERVER_HOST = "127.0.0.1";
