IoT 中心 RegistryManager - 如何從后端更改設備的主鍵？

Question

在 Azure IoT 后端，我如何使用 Microsoft.Azure.Devices.RegistryManager（或其他類，如果這是我需要的）來更改設備的主鍵？

Answer 1

以下行將回收設備對稱密鑰：

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

在僅更改設備主鍵的情況下：

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;

或者你可以簡化它：

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