Ajax Question

postman params not sent to web api controller

I have this web api controller:

public class LoginController : ApiController
private mw2devnew15Entities db = new mw2devnew15Entities();

public string Post()
string authenticationToken = "";
return authenticationToken;

[System.Web.Http.AcceptVerbs("GET", "POST")]
public HttpResponseMessage Post(JObject data)
dynamic json = data;

LoginForm loginF = new LoginForm();
loginF.username = json.username;
loginF.password = json.password;

return Request.CreateResponse(HttpStatusCode.OK);

I'm able to post correctly with this ajax call:

type: "POST",
url: "http://localhost:5832/api/Login",
data: JSON.stringify({ username: 'joep11aul1234', password: '1212213' }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {

But when I'm trying to use Postman to place POST call, the JObject is null.

Any idea why?


Using Postman you're not reproducing the same request as your JavaScript code since you posting the parameters in the query string. What you shoud do instead is something like this:

Add a content type header with the value of application/json:

and for your request body select raw and then add your JSON:

this will send the following request same as your JavaScript code:

POST /api/Login HTTP/1.1
Host: localhost:5832
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: 4bf25ded-7548-77f9-3389-fa16a5d50087

{ "username": "joep11aul1234", "password": "1212213" }
