I want to mimic behaviour of existing web service. Here is a very simplified example showing what I want to achieve.

I use ASP.Net Web API routing: it's quite simple to configure routes with it.

Requirements, part 1: query:

GET whatever.../Person/1

shall return JSON:

Content-Type: application/json; charset=utf-8
"id":1,"name":"Mike"

That's piece of cake:

public class Person

 public int ID get; set; 
 public string Name get; set; 


// In ApiController
[HttpGet]
[Route("Person/id")]
public Person GetPerson(int id)

 return new Person
 
 ID = id,
 Name = "Mike"
 ;

Requirements, part 2: query:

GET whatever.../Person/1?callback=functionName

shall return javascript:

Content-Type: text/plain; charset=utf-8
functionName("id":1,"name":"Mike");

Any ideas how to achieve this (part 2)?

The ApiController would need to be modified to satisfy the desired behavior

Simple example based on provided code

//GET whatever.../Person/1
//GET whatever.../Person/1?callback=functionName
[HttpGet]
[Route("Person/id:int")]
public IHttpActionResult GetPerson(int id, string callback = null) 
 var person = new Person 
 ID = id,
 Name = "Mike"
 ;

 if (callback == null) 
 return Ok(person); // "id":1,"name":"Mike"
 

 var response = new HttpResponseMessage(HttpStatusCode.OK);

 var json = JsonConvert.SerializeObject(person);

 //functionName("id":1,"name":"Mike");
 var javascript = string.Format("0(1);", callback, json);

 response.Content = new StringContent(javascript, Encoding.UTF8, "text/plain");

 return ResponseMessage(response);

Of course you would need to do proper validation on the call back as this currently open up the API for script injection.
