无法将JSON对象发布到asp.net webapi

我需要将以下json对象传递给我的asp.net core 3.1 Web API

{
    "client": {
        "clientID": "3529",
        "clientData": "This a test data"
    },
    "selectedUserIDs": [
        3549,
        3567,
        3546,
        3561,
        3532       
    ],
    "selectedDepartmentsIDs": [
        10695,
        71,
        72,
        121     
       
    ]
}

现在如何在我的Web API中访问此对象？以下是我的api控制器

[HttpPost("/api/client/{id}/savedata")]
public ActionResult SaveClientDetails(int workflowID, [FromBody] Clientdata data)
{            
    //save operation        
}

以下是我的clientdata类

public class clientdata
{
    public client client{ get; set; }
    public List<selectedUserIDs> selectedUserIDs{ get; set; }
    public List<selectedDepartmentsIDs> selectedDepartmentsIDs { get; set; }
}

和客户端类

public class client 
{
    public string clientID { get; set; }
    public string clientData { get; set; }
}

和selectedUserIDs类如下

public class selectedUserIDs
{        
    public int Ids{ get; set; }
}

和selectedDepartmentsIDs类如下

public class selectedDepartmentsIDs
{        
    public int Ids{ get; set; }
}

但是我无法在Web API主体中访问此复杂对象

在邮递员中引发以下错误

{
    "type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
    "title": "One or more validation errors occurred.",
    "status": 400,
    "traceId": "|10eabbbb-4a15387d9152b7d6.",
    "errors": {
        "$.selectedUserIDs[0]": [
            "The JSON value could not be converted to System.Collections.Generic.List`1[ClientCoreAPI.Client.Entity.selectedUserIDs]. Path: $.selectedUserIDs[0] | LineNumber: 6 | BytePositionInLine: 12."
        ]
    }
}

您对的定义clientdata与json文件不匹配。您有两种选择：

更改clientdata为：

 public class clientdata
 {
     public client client{ get; set; }
     public List<int> selectedUserIDs{ get; set; }
     public List<int> selectedDepartmentsIDs { get; set; }
 }

或者将json更改为

{
    "client": {
        "clientID": "3529",
        "clientData": "This a test data"
    },
    "selectedUserIDs": [
        { "Ids": 3549 },
        { "Ids": 3567 },
        { "Ids": 3546 },
        { "Ids": 3561 },
        { "Ids": 3532 }       
    ],
    "selectedDepartmentsIDs": [
        { "Ids": 10695 },
        { "Ids": 71 },
        { "Ids": 72 },
        { "Ids": 121 }
    ]
}
