我的控制器中有这个 post 方法

[HttpPost]
public Task<AddClientAppSettingResponse> Post(AddClientAppSettingCommand mysetting)
    => Mediator.Send(mysetting);

AddClientAppSettingCommand如您所见，我的 post 方法接受一个模型：

public class AddClientAppSettingCommand : IRequest<AddClientAppSettingResponse>
{
        public ClientAppSettings Setting { get; set; }

        public AddClientAppSettingCommand(ClientAppSettings setting)
        {
            Setting = setting;
        }
}

这是我的模型类：

public class ClientAppSettings : BaseEntity
{
        public ClientAppSettings(string userId) : base($"ClientAppSettings/{userId}")
        {
        }

        public bool LightTheme { get; set; }
        public OrderSettings Order { get; set; }
        public NotchSettings Notch { get; set; }
        public int PageSize { get; set; }
        public bool ApplyCommissionInPortfolio { get; set; }
        public bool UseClosingPriceInPortfolioTotalValue { get; set; }
        public bool ShowNotifications { get; set; } = true;
        public bool NoSleep { get; set; } = true;
        public bool NoBalance { get; set; } = false;
        public bool DataTracker { get; set; } = false;
        public bool UserStatusBarToUp { get; set; } = false;
        public bool PortfolioBasedOnLastPositivePeriod { get; set; } = false;
}

public class OrderSettings
{
        public long BuyQuantity { get; set; }
        public long SellQuantity { get; set; }
        public float Tick { get; set; }
        public string TickType { get; set; }
        public bool PriceFromHeadline { get; set; }
        public bool OrderConfirmation { get; set; }
        public bool DivideOrderToMultiple { get; set; }
}

public class NotchSettings
{
        public bool Up { get; set; }
        public bool Down { get; set; }
}

但是当我使用具有这些值的邮递员呼叫我的 API 时

{
   "setting":{
      "LightTheme":true,
      "Order":{
         "BuyQuantity":"1",
         "SellQuantity":"1",
         "Tick":"1.0",
         "TickType":"asas",
         "PriceFromHeadline":true,
         "OrderConfirmation":true,
         "DivideOrderToMultiple":true
      },
      "Notch":{
         "Up":true,
         "Down":true
      },
      "PageSize":"10",
      "ApplyCommissionInPortfolio":true,
      "UseClosingPriceInPortfolioTotalValue":true,
      "ShowNotifications":true,
      "NoSleep":true,
      "NoBalance":true,
      "DataTracker":true,
      "UserStatusBarToUp":true,
      "PortfolioBasedOnLastPositivePeriod":true
   }
}

我收到这个错误

作为一个说明我用MediatR的CQRS，我跟着这个，但没有奏效。我把[JsonConstructor]上

 public AddClientAppSettingCommand(ClientAppSettings setting)
        {
            Setting = setting;
        }

但它没有用。我的变量setting为空

uj5u.com热心网友回复：

您需要一个用于 api 输入自变量的无自变量建构式

public class AddClientAppSettingCommand : IRequest<AddClientAppSettingResponse>
{
        public ClientAppSettings Setting { get; set; }

        public AddClientAppSettingCommand() {}
       

        public AddClientAppSettingCommand(ClientAppSettings setting)
        {
            Setting = setting;
        }
}

和设定相同

public class ClientAppSettings : BaseEntity
{
public ClientAppSettings(){}
      
}
