注册表的AddDeviceAsync方法抛出异常ArgumentNull。 参数、registryManager和输出参数notjing为空但仍然抛出异常。
异常:{"Message":"ErrorCode:ArgumentNull;BadRequest","ExceptionMessage":"跟踪 ID:adf7e83e7db046969086702500cbe73b-G:2-TimeStamp:03/21/2018 14:09:50"} 方法:ProjectXXX。 NTB.FN.DeviceRegistration.IdentityCreationService.CreateDeviceIdentity() 描述:意外异常
它是否与 Microsoft.Azure.Devices 库相关？
代码
RegistryManager registryManager = null;
void Initialize()
{
registryManager = RegistryManager.CreateFromConnectionString(AppSetting.IoTHubConnectionString);
}
public async Task<string> CreateDeviceIdentity(string deviceId, string deviceKey)
{
Device device = new Device(deviceId);
Device newdevice = new Device();
Exception exception = null;
bool bExceptionHasOccured = false;
string token = string.Empty;
string primarySasToken = Base64Encode(deviceKey);
string secondarySasToken = Base64Encode($"{deviceId}-{deviceId}");
device.Authentication = new AuthenticationMechanism
{
SymmetricKey = new SymmetricKey
{
PrimaryKey = primarySasToken,
SecondaryKey = secondarySasToken
}
};
try
{
newdevice = await registryManager.AddDeviceAsync(device);
break;
}
catch (DeviceAlreadyExistsException)
{
token = GetDeviceToken(deviceId);
break;
}
catch (IotHubThrottledException e)
{
}
catch (SocketException e)
{
}
catch (Exception e)
{
}
token = newdevice.Authentication.SymmetricKey.PrimaryKey;
return token;
}

最佳答案
当我将 Microsoft.Azure.Devices 从 1.5.1 降级到 1.3.2 时，它起作用了
