Method 1
public IActionResult GetTopInfor([FromBody] JObject p)
In your action method, we can find that it accepts a JObject type parameter.
Firstly, please note that JObject is a class that belongs to Newtonsoft.Json, since .NET Core 3, the default JSON serializer for ASP.NET Core is now System.Text.Json.
To make it can handle JObject parameter well, please check if you add Newtonsoft.Json (Json.NET) support by calling AddNewtonsoftJson, for more information, please check following doc:
Besides, please debug your code to trace the actual value of p and check if any exception is thrown while you invoke your custom service _orderService.GetTopInfor(row).
Test Result
Method 2
You can use ex.Message.ToString() instead of GetErrorMsg(6).
Method 3
When dealing with JObject, you get the value using GetValue() method.
try this :
row = Int32.Parse(p.GetValue("row").ToString());
also, your code is a bit all over the place. you should rearrange it to make it more readable.
