获取文件的uid和gid

Question

在Linux中，stat结构包含文件的UID和GID。

是否可以使用Go（lang）获取文件的相同信息（UID和GID）？

Answer 1

我想出了一种合理的方法。

import (
    "syscall"
    "os"
)

info, _ := os.Stat("/path/to/the/file")

var UID int
var GID int
if stat, ok := info.Sys().(*syscall.Stat_t); ok {
    UID = int(stat.Uid)
    GID = int(stat.Gid)
} else {
    // we are not in linux, this won't work anyway in windows, 
    // but maybe you want to log warnings
    UID = os.Getuid()
    GID = os.Getgid()
}
