针对于 BytesToString 发现两个参考:

  • unsafe.String(unsafe.SliceData(b), len(b)) 源自 strings.Builder String()
  • unsafe.String(&b[0], len(b)) 源自 strings.Clone
    个人也是倾向于后者,但这个确实对强迫症患者造成了一些纠结,哈哈。

不过需要注意使用后者的话,需要先判断长度

func BytesToString(b []byte) string {
	if len(b) == 0 {
		return ""
	}
	return unsafe.String(&b[0], len(b))
}

from go-questions.
