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()
}

thank you that was very useful, but the problem with this code is that it is usable only once, i.e: if you read once the next time you have an empty output.

Nice code, better do aN err check for ReadFrom.
usable only once is because the nature of the steam

👍

nice

io.Copy is much faster than using ReadFrom method.
