Azure IoT C SDK 配置持续失败

问题描述 投票：0回答：1

我已在 Debian（在 Virtual Box 虚拟机上）上克隆并构建了 azure-iot-sdk-c。我在调整 prov_dev_client_sample 并使其正常工作时遇到问题。我只是无法在 IoT 中心上配置我的 Debian 设备。

我已详细完成创建 IoT 中心、DPS、链接它们，然后为 DPS 创建对称密钥注册的所有步骤。 id_scope 是正确的。对称密钥设置中的主密钥在prov_dev_set_symmetry_key_info中使用。我也尝试过辅助键。

这是我的 prov_dev_client_sample 代码：

无论如何，我都会收到以下未经授权的错误。

我已经尝试一遍又一遍地重新创建 IoT 中心和 DPS 等。这里可能有什么问题？谢谢

确保您提供注册 ID、主密钥、ID 范围的详细信息，并确保共享访问策略具有此权限以避免“未经授权”错误。

按照所提供的文档中的指南，我使用 Azure 设备配置服务 (DPS) 和 C 中的对称密钥证明成功将设备连接到 Azure IoT 中心。请记住链接 IoT 中心，在注册期间包括目标 IoT 中心创建，并根据需要添加例外。

  • 选择“管理注册”选项，然后选择“个人注册”。

  • 证明机制：选择“对称密钥”。

  • 对称密钥设置：您可以自动生成密钥或提供自己的密钥。

  • 注册ID：为设备提供唯一的ID。

  • 其他详细信息：根据您的要求设置配置状态、重新配置策略和其他选项。

  • 添加目标 IoT 中心。

  • 代码取自git

        prov_device_result = Prov_Device_Register_Device(prov_device_handle, register_device_callback, NULL, registration_status_callback, NULL);

        if (prov_device_result == PROV_DEVICE_RESULT_OK)
        {
            (void)printf("\r\nRegistering Device\r\n\r\n");
            do
            {
                ThreadAPI_Sleep(1000);
            } while (!g_registration_complete);
        }
        else
        {
            (void)printf("\r\nRegistering failed with error: %d\r\n\r\n", prov_device_result);
        }

        Prov_Device_Destroy(prov_device_handle);
    }
    prov_dev_security_deinit();

    // Free all the sdk subsystem
    IoTHub_Deinit();

    (void)printf("Press enter key to exit:\r\n");
    (void)getchar();

    return 0;
}

输出：
