json.Unmarshal with disallowUnknownFields

[Brian Candler]

I want to do a json.Unmarshal of []byte data whilst also getting the disallowUnknownFields behaviour.  Is there any tidier way than this?

dec := json.NewDecoder(bytes.NewReader(data))

dec.DisallowUnknownFields()

var v mystruct

err := dec.Decode(&v)

You could write a function to do that for you.

Sure, I now have this as a drop-in replacement for json.Unmarshal:

func StrictUnmarshal(data []byte, v interface{}) error {

dec := json.NewDecoder(bytes.NewReader(data))

dec.DisallowUnknownFields()

return dec.Decode(v)

}

I just wondered if I was missing something.
