Golang: io.Reader stream to string or byte slice

StreamToString.go

import "bytes"

func StreamToByte(stream io.Reader) []byte {
  buf := new(bytes.Buffer)
	buf.ReadFrom(stream)
	return buf.Bytes()
}

func StreamToString(stream io.Reader) string {
	buf := new(bytes.Buffer)
	buf.ReadFrom(stream)
	return buf.String()
}

io.Copy is much faster than using ReadFrom method.
