c# - Azure 函数 - 队列触发器将 DateTimeOffset 返回为 null

Question

我正在运行一个 Azure Function，它连接到 API、获取一些数据并将其保存到 Azure 中的队列中。

然后我有另一个 Azure 函数作为该队列上的触发器运行，但我在 DateTimeOffset 方面遇到了一些问题？数据中对象之一的属性。所有其他属性均按预期工作。

简化的示例代码:

运行.csx:

using System;
using System.Collections.Generic;
using GoApi;
using GoApi.Reporting.AccountTransactions;

public static void Run(ReverseFactoringTransaction myQueueItem, TraceWriter log)
{
    log.Info(myQueueItem.Transaction.CreatedDate.ToString());
    log.Info(myQueueItem.Transaction.Text.ToString());
    log.Info(myQueueItem.Transaction.Amount.ToString());
    log.Info(myQueueItem.Transaction.Date.ToString());
    log.Info(myQueueItem.Partner.Name.ToString());
    log.Info(myQueueItem.Partner.IsActive.ToString());
    log.Info(myQueueItem.Partner.CreatedDate.ToString());
    log.Info(myQueueItem.LastSynchronizationDate.ToString());
    log.Info(myQueueItem.PostOnCreatedDate.ToString());
}

public class Auditable
{
    public string CreatedBy { get; set; }
    public string UpdatedBy { get; set; }
    public DateTime CreatedDate { get; set; }
    public DateTime UpdatedDate { get; set; }
}

public class Client : Auditable
{
    public Guid Id { get; set; }
    public long? CustomerId { get; set; }
    public string Name { get; set; }
    public string ClientKey { get; set; }
    public bool IsManuallyRecognized { get; set; }
    public bool IsActive { get; set; }
    public Guid PartnerId { get; set; }
    public Partner Partner { get; set; }
}

public class Partner : Auditable
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public string PartnerKey { get; set; }
    public bool IsActive { get; set; }
    public List<Client> Clients { get; set; }
}

public class ReverseFactoringTransaction
{
    public Partner Partner { get; set; }
    public AccountTransaction Transaction { get; set; }
    public int ReverseAccountCode { get; set; }
    public DateTimeOffset LastSynchronizationDate { get; set; }
    public bool PostOnCreatedDate { get; set; }
}

项目.json:

{
    "frameworks":
    {
        "net46":
        {
            "dependencies":
            {
                "PowerOfficeGoSDK": "1.6.3"
            }
        }
    }
}

当我使用此测试输入时:

{
  "Partner": {
    "Id": "da462e01-d999-41d0-a71d-dbcf36ca219b",
    "Name": "Test Acme",

    "IsActive": true,
    "CreatedBy": "sth",
    "UpdatedBy": "sth",
    "CreatedDate": "2017-10-18T07:40:16.3244273+00:00",
    "UpdatedDate": "2017-10-18T07:40:16.3244273+00:00"
  },
  "Transaction": {
    "Id": 4889211,

    "VoucherCID": "141",
    "VoucherId": "95620904-623a-48b6-99a4-6316d893886b",

    "CreatedFromImportJournalId": "1c9d60cf-9cc0-409e-9b3e-787461a0ae96",
    "IsCreatedFromEhf": false
  },
  "ReverseAccountCode": 1510,
  "LastSynchronizationDate": "2017-01-18T00:00:00+00:00",
  "PostOnCreatedDate": true,
  "$AzureWebJobsParentId": "765c4f56-0cdb-4d08-b9fa-8bc4a94e0499"
}

我得到这个作为函数的输出:

2017-10-18T08:05:50.391 Function started (Id=bb8f485c-9f33-4976-833f-4a1ac0840e22)

如您所见，DateTimeOffset？ Transaction 对象上的 CreatedDate 显示为 null。但我完全不知道为什么。 有谁知道问题出在哪里吗？

Answer 1

AccountTransaction.CreatedDate 有内部 setter，因此在反序列化期间它将被忽略。

参见this question用于内部属性反序列化的描述。

如果您确实需要它，您可以接受队列项目作为字符串，然后使用自定义设置/解析器手动反序列化。
