ASP.NET Core Web API将所有枚举发布为第0个选项

我已经开始构建一个webapi。我有一个像这样的模型类：

public class ParentItem
    {
        public long Id { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Address { get; set; }
        public string Profession { get; set; }
        public string PhoneNumber { get; set; }
        public CaretakerType Caretaker { get; set; }
        public string Email { get; set; }
        
    }

    public enum CaretakerType 
    {
        Father,
        Mother,
        LegalGuardian,
        EmergencyContact
    }

目前的post方法只是默认方法

        [HttpPost]
        public async Task<ActionResult<ParentItem>> PostParentItem(ParentItem parentItem)
        {
            _context.ParentItems.Add(parentItem);
            await _context.SaveChangesAsync();

            return CreatedAtAction(nameof(GetParentItem), new { id = parentItem.Id }, parentItem);
        }

但是，每当我用邮递员测试post方法时，就像这样：

{
    "firstName": "Person",
    "lastName" : "Name",
    "address" : "an address",
    "profession": "a profession",
    "phoneNumber": "a number",
    "caretakerType": "Mother",
    "email": "an email"
}

使用Raw单选按钮并作为JSON类型，它总是返回

{
    "id": 1,
    "firstName": "Person",
    "lastName": "Name",
    "address": "an address",
    "profession": "a profession",
    "phoneNumber": "a number",
    "caretaker": "Father",
    "email": "an email"
}

我说母亲，LegalGuardian或EmergencyContact并不重要，它总是以“父亲”的身份出现。为什么是这样？目标框架是net5.0。我目前正在使用EntityFrameworkCore.SqlServer和EntityFrameworkCore.InMemory。

JSON的名称与DTO类的属性名称不同。

public class ParentItem
    {
        public long Id { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string Address { get; set; }
        public string Profession { get; set; }
        public string PhoneNumber { get; set; }
        public CaretakerType Caretaker { get; set; }  // <---- "Caretaker"
        public string Email { get; set; }
        
    }

{
    "firstName": "Person",
    "lastName" : "Name",
    "address" : "an address",
    "profession": "a profession",
    "phoneNumber": "a number",
    "caretakerType": "Mother",            // <-- "caretakerType"
    "email": "an email"
}

将您的JSON更改为此：

{
    "firstName": "Person",
    "lastName" : "Name",
    "address" : "an address",
    "profession": "a profession",
    "phoneNumber": "a number",
    "caretaker": "Mother",            // <-- "caretaker"
    "email": "an email"
}
