Get-request sends null in web api

Question

I have an action for a GET-reqeust:

[HttpGet]
public string Answer([FromBody]string value)
{
    CookieHeaderValue cookie = Request.Headers.GetCookies("user").FirstOrDefault();
    game.LogUserAnswer(cookie["user"].Value, value);
    return String.Format("<strong>{0}</strong>: {1} <br>", cookie["user"].Value, game.UserGuess(value));
}

When I'm trying to pass any data I've always got null. I invoke the action with ajax-call:

$('#btnAnswer').click(function () {
    var value = $('#Answer').val();
    $.ajax({
        type: "GET",
        dataType: "json",
        url: uri + '/' + 'Answer' + '/' + value,
        data: { '': value },
        success: function (data) {
            $('#resultsBox').append('<strong>' + data + '</strong><br>');
        },
        error: function (error) {
            jsonValue = jQuery.parseJSON(error.responseText);
        }
    });
});

In the Fiddler the url is next: GET /api/values/Answer/132312?=132312 HTTP/1.1 I tried to send another request: GET /api/values/Answer/132312 HTTP/1.1 but still in my action value is null.

Also I've changed public string Answer(string value) (without FromBody), in this case application can't find needful HTTP .

Could you please tell, what I'm missing?

*Update 1 * var uri = 'api/values';

config.Routes.MapHttpRoute(
    name: "apianswer",
    routeTemplate: "Home/api/values/answer/{id}",
    defaults: new { action = "Answer", id = RouteParameter.Optional }
);

Get requests does not have body ! You should send your parameter as part of your route

[HttpGet]
[Route("Home/api/values/answer/{value}"]
public string Answer(string value = null //in case you want to call answer without any value provided)
{...}

$.ajax({
    type: "GET",
    url: uri + '/' + 'Answer' + '/' + value,
    ...
});

or as a query string

[HttpGet]
public string Answer(string value)
{...}

$.ajax({
    type: "GET",
    url: uri + '/' + 'Answer',
    data: {value: value}
    ...
});
