ASP.NET HttpPost method. can't receive data properly












2














There's the project, that has Node class declared



public class Node
{
public string id { get; set; }
public int group { get; set; }

public Node( string id, int group)
{
this.id = id;
this.group = group;
}

public Node()
{
}
}


And method, that has to receive this object and do stuff with it



[HttpPost]
public IActionResult Create(Node node)
{
//does stuff here
return NoContent();
}


One thing I can't understand is how my JSON object has to look like to be correctly deserialized in this method. I mean I tried to send JSON that looked like this: { "id": "TEST", "group": 1} but thing received object with id = null, group = 0. I don't get it, what do I do wrong?

By default, the action method model binding in ASP.net is looking for application/x-www-url-formencoded encoded form values.



You are POSTing JSON in the body of your request, so you need to use the [FromBody] attribute.



[HttpPost]
public IActionResult Create([FromBody] Node node)
{
//does stuff here
return NoContent();
}

If you are ever struggling with deserializing a body, try and do it manually to see if you are actually sending it correctly.



[HttpPost]
public void Post()
{
string body = Request.Content.ReadAsStringAsync().Result;
}
