Following is a JSON POST data and assume we are passing this data on the body part.

"ShiftStartTime": 0
}
And the following class is your Model.
public class TeamViewModel
{
public long TeamId { get; set; }
public string Name { get; set; }
public double Lat { get; set; }

1. As a Parameter
- Generally, this method is used in most in normal cases so we can see in MVC this is the default case to get JSON POST data from the body as a parameter.
public ActionResult Index(TeamViewModel model)
{
//TODO
//Write your code here
}
You can see here TeamViewModel pass as a parameter and then utilize for further logic.
2. From Request Object
- Generally, this kind of cases used when directly post request from other pages or same kind of requirement.
public ActionResult Index()
{
Stream req = Request.InputStream;
req.Seek(0, System.IO.SeekOrigin.Begin);
string json = new StreamReader(req).ReadToEnd();
PlanViewModel plan = null;
try
{
// assuming JSON.net/Newtonsoft library from http://json.codeplex.com/
plan = JsonConvert.DeserializeObject<TeamViewModel>(json);
}
catch (Exception ex)
{
// Try and handle malformed POST body
return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
}
//TODO:: you can write your logic here
}
You can see the code, get JSON POST data from the Request object. Once you read StreadReader object and converted into the string.
Then string will convert into TeamViewModel object help of JsonConvert.DeserializeObject method and finally get the TeamViewModel object.
