ConverToString.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()
}

I have improve and other way to convert.

func StreamToString(stream io.Reader) string {
     b, _ := ioutil.ReadAll(stream)
     
    return  string(b)
}
