Unity3D post a json to ASP.NET MVC 4 Web Api

Question

How I do a post with json value to a ASP.NET MVC 4 Web Api Controller? I tried it several ways, but I can\'t make it works.

First, my simplified Controller action:

Answer 1

Do not use WWWForm to post JSON. Use something like this.

string input = "You JSON goes here";

Hashtable headers = new Hashtable();
headers.Add("Content-Type", "application/json");

byte[] body = Encoding.UTF8.GetBytes(input);

WWW www = new WWW("http://yourserver/path", body, headers);

yield www;

if(www.error) {
         Debug.Log(www.error);
}
else {
        Debug.Log(www.text);
}

Assuming JSON string in input is like this,

{"Id":15,"Name":"Teste","Description":"Teste","Value":0.0,"Time":10.0}

you will need a class like this

public class Interaction
{
   public int Id { get; set; }
   public string Name { get; set; }
   public string Description { get; set; }
   public string Teste { get; set; }
   // other properties
}

for the action method like this to work

public Interaction Post(Interaction filter)
