如何在WCF Rest Service中将类对象作为参数传递

Question

Here is my Interface code

      [OperationContract]
       [WebGet(RequestFormat = WebMessageFormat.Json,
         ResponseFormat = WebMessageFormat.Json,
          BodyStyle = WebMessageBodyStyle.Bare,
          UriTemplate = "/Insert?customer={customer}")]
       void InsertDetailsData(CustomerClass customer);

My Class method is like

      public void InsertDetailsData(CustomerClass cust)
      {
        SqlConnection scon = new SqlConnection(myConnection);
        scon.Open();
        cust.CustomerName = "adsd";
        cust.Address = "asdasd";
        cust.FirstName = "asd";
        cust.LastName = "asda";
        string query = "Insert into TblCustomer(CustomerName,FirstName,LastName,Address)";
        query += " values('" + cust.CustomerName + "','" + cust.FirstName + "','" + cust.LastName + "','" + cust.Address + "')";

        SqlCommand cmd = new SqlCommand(query, scon);
        cmd.ExecuteNonQuery();
        scon.Close();

    }

But I am getting error like

Operation 'InsertDetailsData' in contract 'ICustomerService' has a query variable named 'customer' of type 'CustomerService.CustomerClass', but type 'CustomerService.CustomerClass' is not convertible by 'QueryStringConverter'. Variables for UriTemplate query values must have types that can be converted by 'QueryStringConverter'.

So tried with

  public class MyQueryStringConverter : QueryStringConverter
    {
        public override bool CanConvert(Type type)
        {
            return (type == typeof(CustomerClass)) || base.CanConvert(type);
        }
        public override object ConvertStringToValue(string parameter, Type parameterType)
        {
            if (parameterType == typeof(CustomerClass))
            {
                string[] parts = parameter.Split(',');
                return new CustomerClass { FirstName = parts[0], CustomerName = parts[1], LastName = parts[2], Address = parts[3] };
            }
            else
            {
                return base.ConvertStringToValue(parameter, parameterType);
            }
        }
    }
    public class MyWebHttpBehavior : WebHttpBehavior
    {
        protected override QueryStringConverter GetQueryStringConverter(OperationDescription operationDescription)
        {
            return new MyQueryStringConverter();
        }
    }

Still I am facing same error.

This request is only send simple types, uritemplates make a mapped parametres in method.

[WebGet(UriTemplate = "Method/{Par1}/{par2}")]

if you want to pass class must be use POST method WebInvoke.
