使用 BrokeredMessage 从 Azure 服务总线队列 (v1) 反序列化强类型对象

无论出于何种原因，我似乎无法弄清楚如何将我的对象从队列中取出并将其反序列化回它放入其中的内容（An账户事件DTO).

Azure函数成功将对象放入队列：

[FunctionName("AccountCreatedHook")]
public static async Task<HttpResponseMessage> Run([HttpTrigger(AuthorizationLevel.Function, "post", Route = null)]HttpRequestMessage req,
    TraceWriter log, [ServiceBus("topic-name", Connection = "BusConnectionString", EntityType = Microsoft.Azure.WebJobs.ServiceBus.EntityType.Topic)] IAsyncCollector<BrokeredMessage> accountCreatedTopic)
{
    var accountEvent = await req.Content.ReadAsAsync<AccountEventDTO>();

    if (accountEvent != null && accountEvent.Name != null)
    {
        // Serialization
        var bytes = Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(accountEvent));
        var memoryStream = new MemoryStream(bytes, writable: false);
        var message = new BrokeredMessage(memoryStream) { SessionId = Guid.NewGuid().ToString() };

        await accountCreatedTopic.AddAsync(message);
        return req.CreateResponse(HttpStatusCode.OK, "Account successfully added to topic.");
    }

    return req.CreateResponse(HttpStatusCode.BadRequest, "Account was not formed well.");
}

Azure函数从队列中提取对象：

[FunctionName("AccountCreatedSubscriber")]
public static void Run([ServiceBusTrigger("topic-name", "license-keys", Connection = "BusConnectionString")]BrokeredMessage accountEvent, ILogger log)
{
    // ERROR on this line during deserialization
    var account = accountEvent.GetBody<AccountEventDTO>();

    var accountAddedEvent = Mapper.Map<AccountEventDTO, AccountAddedEvent>(account);
    _accountHandler.Handle(accountAddedEvent);
    GenericLogger.AccountLogging(log, accountAddedEvent);
}

错误信息：

帐户事件DTO：

public class AccountEventDTO : IAccountEvent
{
    public string Name { get; set; }
    public string SugarId { get; set; }
    public string AccountSubTypeRaw { get; set; }
    public AccountType AccountType { get; set; } = AccountType.Customer;
    public AccountSubType? AccountSubType { get; set; } = null;
    public string Phone { get; set; }
    public string PhoneAlternate { get; set; }
    public string BillingAddressCity { get; set; }
    public string BillingAddressCountry { get; set; }
    public string BillingAddressPostalCode { get; set; }
    public string BillingAddressState { get; set; }
    public string BillingAddressStreet { get; set; }
    public string ShippingAddressCity { get; set; }
    public string ShippingAddressCountry { get; set; }
    public string ShippingAddressPostalCode { get; set; }
    public string ShippingAddressState { get; set; }
    public string ShippingAddressStreet { get; set; }
    public string Website { get; set; }
}

你正在使用BrokeredMessage（适用于 .NET 的旧 Azure 服务总线客户端，WindowsAzure.ServiceBus https://www.nuget.org/packages/WindowsAzure.ServiceBus/）。当消息作为内存流发送时，必须使用相同的方法接收和反序列化消息。GetBody<T>如果你构建就会起作用BrokeredMessage传入一个类型的对象T.

注：下一代客户端（微软Azure服务总线 https://www.nuget.org/packages/Microsoft.Azure.ServiceBus/）仅适用于字节数组（旧客户端的内存流）。如果这是一个新项目，建议坚持使用该方法而不是序列化类型。更多信息可在 GitHub 问题中找到here https://github.com/Azure/azure-service-bus-dotnet/issues/239.
