Can you make this as a full runnable example on play.golang.org ?

What type is a "db.Visitor"?

When I compile my code it throw error like this 0xc54f40 , 0xc000032070.

It will show more than that.  Please show the complete error message.

Do not use print to print messages. That's an internal function. Use
fmt.Printf, it should tell you the error.

I suspect your client isn't providing the required JSON body when making the request. Try reading the body with `ioutil.ReadAll` before decoding with `json.Unmarshal` so you can see exactly what's being provided.
