為ASP.NETCore的GET請求序列化復雜物件

所以，以前我的團隊對所有事情都使用 POST 請求。我終于在說服他們按預期使用動詞方面贏得了戰爭。
GET 用于查詢，
POST 用于創建等。

我們有一個非常復雜的物件，我們需要將其作為 GET 發送：

{
    "UserId": "1",
    "CategoryId": "39",
    "StartMillis": 1609459200000,
    "EndMillis": 1635724799000,
    "GroupByAttributeTypeId": "105",
    "SelectedAttributes": [{
            "TypeId": "100",
            "AttributeIds": [1]
        }, {
            "TypeId": "105",
            "AttributeIds": [6697]
        }
    ]
}

這就像 POST 一樣簡單，但不如 GET。Action我們創建的方法類似于：

[HttpGet]
[Route(AspNet.Mvc.ActionTemplate)]

public IActionResult GetCompletedAudits([FromQuery]CompletedAuditDto payload)
{
   return OkResponse(_auditService.GetCompletedAudit(payload));
}

在哪里CompletedAuditDto：

public class CompletedAuditDto
{
    public int UserId { get; set; }
    public string CategoryId { get; set; }
    public long StartMillis { get; set; }
    public long EndMillis { get; set; }
    public string GroupByAttributeTypeId { get; set; }

    public IEnumerable<TypeAttributeDto> SelectedAttributes;
}

并且TypeAttributeDto是：

public class TypeAttributeDto
{
    public int TypeId;
    public IEnumerable<int> AttrIds;
}

我已經使用qs庫嘗試了許多不同的序列化。但該SelectedAttributes集合總是為空。我將日志記錄降低到debug級別，模型系結器甚至似乎都沒有嘗試反序列化該物件（沒有提到SelectedAttributes集合）

[14:35:44 DBG] Attempting to bind parameter 'payload' of type 'WebApp.Payloads.Request.CompletedAuditDto' ...

[14:35:44 DBG] Done attempting to bind parameter 'payload' of type 'WebApp.Payloads.Request.CompletedAuditDto'.

任何想法如何將其序列化為模型系結器會滿意的格式。這是我嘗試過的眾多事情之一：

UserId=1&CategoryId=39&StartMillis=1609459200000&EndMillis=1635724799000&GroupByAttributeTypeId=105&SelectedAttributes[].TypeId=100&SelectedAttributes[].Attribute[].AttributeIds[Attribute]Attribute]Attribute]Attribute]Attribute]Attribute%SelectAttribute[[ 6697

uj5u.com熱心網友回復：

首先，您需要在模型中添加 getter setter，如下所示：

public class CompletedAuditDto
{
    public int UserId { get; set; }
    public string CategoryId { get; set; }
    public long StartMillis { get; set; }
    public long EndMillis { get; set; }
    public string GroupByAttributeTypeId { get; set; }

    public IEnumerable<TypeAttributeDto> SelectedAttributes { get; set; }
}
public class TypeAttributeDto
{
    public int TypeId { get; set; }
    public IEnumerable<int> AttrIds { get; set; }
}

然后發送如下請求：

UserId=1&CategoryId=39&StartMillis=1609459200000&EndMillis=1635724799000&GroupByAttributeTypeId=105&SelectedAttributes[0].TypeId=100&SelectedAttributes[0].AttrIds=1].5TypeIds=1&SelectedTypeIds9AttrIds=1&Selected6TypeIds[7
