golang: 给二进制文件增加版本信息

一，代码：

package main

import (
	"embed"
	"flag"
	"github.com/gofiber/template/html/v2"
	"net/http"
	"fmt"
	"runtime"
	"industry/config"
	"industry/routes"
)


// 构建版本信息
var (
	Version   = ""
    GitCommit  = ""
	BuildTime      = ""
)

func main() {

	// 构建信息，golang版本 commit id 时间
	var version bool
	versionFlag := flag.Bool("version", false, "print version information and exit")
	flag.BoolVar(&version, "v", false, "version")
	flag.Parse()
	if version || *versionFlag {
		//"OS/Arch":    runtime.GOOS + "/" + runtime.GOARCH,
		fmt.Printf("App version: %s\ngo version: %s\nOS/Arch: %s\nGitCommit: %s\nBuild time: %s\n",
			Version, runtime.Version(), runtime.GOOS + "/" + runtime.GOARCH, GitCommit, BuildTime)
		return
	}

    

 

二，测试效果:

$ go build -ldflags "-X main.Version=1.0.0 -X main.BuildTime=2024.11.23 -X main.GitCommit=b554659"
$ ./industry -v
App version: 1.0.0
go version: go1.23.3
OS/Arch: linux/amd64
GitCommit: b554659
Build time: 2024.11.23
$ ./industry --version
App version: 1.0.0
go version: go1.23.3
OS/Arch: linux/amd64
GitCommit: b554659
Build time: 2024.11.23

说明：build时的-ldflags参数，可以用脚本获取或者写入到Makefile中
