IoT中心HubManager-如何从后端更改设备的主键？

Question

在Azure IoT后端中，如何使用Microsoft.Azure.Devices.RegistryManager（或其他类（如果需要的话）来更改设备的主键？

Answer 1

以下行将回收设备对称密钥：

var device = registryManager.UpdateDeviceAsync(new Device(deviceId), true).Result;

仅更改设备主键的情况：

var device = registryManager.GetDeviceAsync(deviceId).Result;
var auth = new AuthenticationMechanism();
auth.SymmetricKey.PrimaryKey = "<new primary key>";
auth.SymmetricKey.SecondaryKey = device.Authentication.SymmetricKey.SecondaryKey;
device = registryManager.UpdateDeviceAsync(new Device(deviceId) { Authentication = auth}, true).Result;

或者您可以简化它：

var device = registryManager.GetDeviceAsync(deviceId).Result;
device.Authentication.SymmetricKey.PrimaryKey = "<new primary key>";
device = registryManager.UpdateDeviceAsync(device, true).Result;
