Asp.net web api 如何通过postman将自定义对象数组作为多种形式的数据内容发送到asp.net web api？

如何通过Postman将自定义对象数组正确发送到asp.net web api？我所做的是：

自定义类：

public class SystemConsumerConfiguration
    {
        public int SystemId { get; }
        public Uri CallbackUrl { get; }

        public SystemConsumerConfiguration()
        {
        }

        public SystemConsumerConfiguration(int systemId, Uri callbackUrl)
        {
            SystemId = systemId;
            CallbackUrl = callbackUrl;
        }
   }

public class PostDigitalPostSubscriptionConfiguration
    {
        public IReadOnlyList<SystemConsumerConfiguration> SystemsModel { get; set; }

        public IFormFile Certificate { get; set; }


        public PostDigitalPostSubscriptionConfiguration()
        {
        }
    }

在REST API中查看模型：

public class SystemConsumerConfiguration
    {
        public int SystemId { get; }
        public Uri CallbackUrl { get; }

        public SystemConsumerConfiguration()
        {
        }

        public SystemConsumerConfiguration(int systemId, Uri callbackUrl)
        {
            SystemId = systemId;
            CallbackUrl = callbackUrl;
        }
   }

public class PostDigitalPostSubscriptionConfiguration
    {
        public IReadOnlyList<SystemConsumerConfiguration> SystemsModel { get; set; }

        public IFormFile Certificate { get; set; }


        public PostDigitalPostSubscriptionConfiguration()
        {
        }
    }

公共类PostDigitalPostSubscriptionConfiguration
{
公共IReadOnlyList系统模型{get；set；}
公共文件证书{get；set；}
公共PostDigitalPostSubscriptionConfiguration（）
{
}
}

现在，我向邮递员提出了一个请求

问题是，该模型与默认值绑定：

忘记在

系统消费者配置中设置公共设置器

应该是这样的：

public class SystemConsumerConfiguration
    {
        public int SystemId { get; set; }
        public Uri CallbackUrl { get; set; }

        public SystemConsumerConfiguration()
        {
        }

        public SystemConsumerConfiguration(int systemId, Uri callbackUrl)
        {
            SystemId = systemId;
            CallbackUrl = callbackUrl;
        }
   }

答复如下：
