如何从Postman发送请求到ASP.Net MVC中的功能？

Question

我在尝试从Postman发送请求到Class函数时遇到问题。

这是我的代码：

 public ChargeInitResponse Post([FromBody]LocaliseChargeInit value)
        {
            if (value == null)
            {
                throw new HttpResponseException(HttpStatusCode.BadRequest);
            }

            ChargeInitResponse reply = new PaymentIntegrationService
            {
                ChargeInitRequest = value
            }.PushChargeInit();

            if (reply == null)
            {
                throw new HttpResponseException(HttpStatusCode.InternalServerError);
            }
            return reply;
        }

ChargeInitResponse类

public class ChargeInitResponse
    {
        public string partnerTxID { get; set; }
        public string request { get; set; }
        public string ErrorMessage { get; set; }
    }

LocaliseChargeInit类

public class LocaliseChargeInit : ChargeInit
    {
        public string CodeVerifier { get; set; }
        public ServiceRequestHeader Header { get; set; }
    }

ServiceRequestHeader类

 public class ServiceRequestHeader
    {
        public string Authorization { get; set; }
        public string Date { get; set; }
    }

所以现在我的问题是我不知道如何通过邮递员向ChargeInitResponse Post发出请求。你有什么建议吗？
