Azure IoThub - 类RegistryManager - 方法AddDeviceAsync(设备)抛出错误代码:ArgumentNull;BadRequest

Question

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;
}

Answer 1

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