FromBody not binding string parameter

I have an issue similar to ASP.NET MVC 4 RC Web API Parameter Binding Issue, but I'm trying to solve it by using the [FromBody] attribute.

Fiddler reports the following request (excluding irrelevant bits like User Agent String)

PUT http://localhost:82/api/account/shoppinglistitems HTTP/1.1
Host: localhost:82
Connection: keep-alive
Content-Length: 11
Origin: http://localhost:3000
Content-Type: application/x-www-form-urlencoded
Accept: application/json, text/javascript, */*; q=0.01

query=apple

My controller action is

[HttpPut]
public ShoppingListItemWebModel CreateShoppingListItem([FromBody]string query) {
    // query is null
}

I could wrap the parameter in a complex type, but that seems like a hack to fix the issue. Or I could put the query in the URI, but that doesn't fit the pattern of the rest of the API. Is it possible to do it this way? If so, where is my mistake?

If you're using AngularJS instead of jQuery you might want to opt for the following alternative, since AngularJS uses content type application/json by default.

PUT http://localhost:82/api/account/shoppinglistitems HTTP/1.1
Host: localhost:82
Connection: keep-alive
Content-Length: 7
Origin: http://localhost:3000
Content-Type: application/json
Accept: application/json, text/javascript, */*; q=0.01

'apple'

Notice that the value is wrapped in string quotes (either single or double).

change your request to be

PUT http://localhost:82/api/account/shoppinglistitems HTTP/1.1
Host: localhost:82
Connection: keep-alive
Content-Length: 11
Origin: http://localhost:3000
Content-Type: application/x-www-form-urlencoded
Accept: application/json, text/javascript, */*; q=0.01

=apple

notice the lack of "query"
