Decode issue: interface is []uint8, not string

[finkel]

Hi there--thanks for providing this library!

I'm in the process of upgrading from your now-deprecated go-msgpack library, where I was using the convenience methods Marshal and Unmarshal. Using this new library, Encode works as a perfect drop in replacement for Marshal, but when I try to decode I get the following runtime error:
"interface is []uint8, not string"
where casting to a string (as it was encoding as a string) worked before. Is this a bug, or has the usage changed?

My Marshal/Unmarshal replacement are:

var mh codec.MsgpackHandle

//Convenience methods for simple encoding/decoding
func MsgpackEncode(val interface{}) (packed []byte, err error) {
enc := codec.NewEncoderBytes(&packed, &mh)
err = enc.Encode(val)
return
}

func MsgpackDecode(packed []byte, val interface{}) (err error) {
dec := codec.NewDecoderBytes(packed, &mh)
err = dec.Decode(&val)
return

}

Appreciate the help.

Yes, previously RawToString was set to true when you created a new DecodeOptions. But I didn't like the automatic conversion.

So now, you have to set it directly (when decoding into a nil interface{}). In your code somewhere (init method, etc), set RawToString option on MsgpackHandle. E.g.

var mh = codec.MsgpackHandle{ RawToString: true } 
OR
var mh codec.MsgpackHandle
mh.RawToString = true

Perfect! Thanks for the help.
