如何在Go中检测操作系统版本 [英] How can I detect OS version in Go
问题描述
相对较新.似乎微不足道,但我不知道如何检测操作系统版本.我知道我可以使用 runtime.GOOS
和 runtime.GOARCH
来获取平台和体系结构,但是我知道我在linux上,但是我想知道是否我正在尝试找出RH6上的m和RH7等上的错误.
Relatively new to Go. Seems trivial, but I can't figure out how to detect the OS version. I know I can use runtime.GOOS
and runtime.GOARCH
to get the platform and architecture, but say I know I'm on linux but I want to find if I'm on RH6 vice RH7, etc. is what I'm trying to figure out.
推荐答案
因此,至少在Linux上, syscall
包中有一个晦涩的 Uname
方法可以做到这一点.填充的结构有点笨拙,没有文档说明,但是您可以了解它的要旨:
So there's this obscure Uname
method in the syscall
package that basically does it, at least on Linux. The struct it fills is a bit clunky and undocumented, but you can get the gist of it:
import (
"fmt"
"syscall"
)
// A utility to convert the values to proper strings.
func int8ToStr(arr []int8) string {
b := make([]byte, 0, len(arr))
for _, v := range arr {
if v == 0x00 {
break
}
b = append(b, byte(v))
}
return string(b)
}
func main() {
var uname syscall.Utsname
if err := syscall.Uname(&uname); err == nil {
// extract members:
// type Utsname struct {
// Sysname [65]int8
// Nodename [65]int8
// Release [65]int8
// Version [65]int8
// Machine [65]int8
// Domainname [65]int8
// }
fmt.Println(int8ToStr(uname.Sysname[:]),
int8ToStr(uname.Release[:]),
int8ToStr(uname.Version[:]))
}
}
BTW这可能在操场上不起作用,可能是由于沙箱限制所致,但在Linux上有效.尚未测试其他系统.
BTW This doesn't work on the playground, probably because of the sandbox limitations, but works on Linux. Haven't tested other systems.
