POST a JSON body with the Sails REST Blueprint?

In Sails 0.10, the default REST blueprint for a create action seems to only accept a POST with the content of the new item via query parameters. I also need to support the POSTing of a JSON body to create the item.

So, POST http://localhost:1337/user?username=George works just fine, but the following does not:

POST http://localhost:1337/user

{
   username: 'George'
}

Is this possible with the default blueprint or must I implement this manually?

I was missing the header: Content-Type: application/json

Now it works like a champ!
