    测试场景：子设备（IotProductDeviceTypeEnum 的 SUB 类型）通过网关设备代理上报数据 + * + *

    重要说明：子设备无法直接连接平台，所有请求均由网关设备（Gateway）代为转发。 + * + *

    支持两种编解码格式： + *

    + * + *

    使用步骤： + *

      + *
    1. 启动 yudao-module-iot-gateway 服务（TCP 端口 8091）
      2. + *
    2. 确保子设备已通过 {@link IotGatewayDeviceTcpProtocolIntegrationTest#testTopoAdd()} 绑定到网关
      3. + *
    3. 修改 {@link #CODEC} 选择测试的编解码格式
      4. + *
    4. 运行以下测试方法： + *
        + *
      • {@link #testAuth()} - 子设备认证
        • + *
      • {@link #testPropertyPost()} - 子设备属性上报（由网关代理转发）
        • + *
      • {@link #testEventPost()} - 子设备事件上报（由网关代理转发）
        • + *
      + *
      5. + *
    + * + *

    注意：TCP 协议是有状态的长连接，认证成功后同一连接上的后续请求无需再携带认证信息 + * + * @author 芋道源码 + */ +@Slf4j +public class IotGatewaySubDeviceTcpProtocolIntegrationTest { + + private static final String SERVER_HOST = "127.0.0.1";
