在Go语言中,io/ioutil包中的ReadAll函数(在早期版本中可能被称为或理解为readall)确实已经被标记为弃用(deprecated)。以下是针对你问题的详细回答: 1. 解释'readall'函数在Go语言中的弃用情况 在Go 1.16版本及以后的更新中,io/ioutil包中的许多函数,包括ReadAll、ReadFile、WriteFile等,都被标记为弃用。Go语言团队...
ReadFrom函数将io.Reader作为参数,也就是说,ReadFrom可以从任意的地方读取数据,只要来源实现了io.Reader接口。 从标准输入、文件、字符串读取数据 示例: go //从标准输入读取 data,err = ReadFrom(os.Stdin,11)//从普通文件读取,其中file是os.File的实例 data,err = ReadFrom(file,9)//从字符床读取 data,e...
err := ioutil.TempFile("", "keepalive") if err != nil { log.Fatal(err) } file.Write([]byte("keepalive")) file.Close() defer os.Remove(file.Name()) p := openFile(file.Name()) content := readFile(p.d) // Ensure p is not finalized until...
