Beego POST request body always empty

Question

I'm working with Beego's convenience methods for parsing request body values and have the following:

Router file:

    apiNamespace := beego.NewNamespace("/api")

    apiNamespace.Router("/sessions/google/new", &controllers.SessionsController{}, "get:GoogleNewSession")

    beego.AddNamespace(apiNamespace)

Controller code:

func (c *SessionsController) URLMapping() {
    c.Mapping("GoogleNewSession", c.GoogleNewSession)
}

func (c *SessionsController) GoogleNewSession() {

    // Always serve JSON
    defer func() {
        c.ServeJson()
    }()

    // This is always blank
    log.Printf("'Received %+v'", c.Ctx.Input.RequestBody)

    c.Ctx.ResponseWriter.WriteHeader(200)
    return

    // truncated
}

Front end JS (super-agent):

    request
    .post('/sessions/google/new')
    .use(prefix)
    .send({ code: authCode })
    .set('Accept', 'application/json')
    .end(function(err, res){
        console.log("******* request", res.request)
         if (res.ok) {
            var body = res.body;
            console.log('yay got ' + JSON.stringify(res.body));
         } else {
            console.log("***** err", err);
            console.log("***** not ok", res.text);
         }
     });

When the superagent request fires off, I can see in the logs that the path is getting correctly matched. However, the c.Ctx.Input.RequestBody is always empty.

I have tried using something else to fire the request such as Postman but to no avail. In GET requests I am able to retrieve query params correctly.

Any clues or suggestions to help fix or debug this issue?

You need to configure "copyrequestbody = true" in configuration file "conf/app.conf".

The default is false so the content is not copied to c.Ctx.Input.RequestBody.

The example is shown section "Retrieving data from request body" in the document. (http://beego.me/docs/mvc/controller/params.md)
