希望了解二进制文件编译时的信息

本地

可以通过go version -m ./binary查看：

$ go version -m ./go-pprof-practice 
./go-pprof-practice: go1.24.2path	github.com/wolfogre/go-pprof-practicemod	github.com/wolfogre/go-pprof-practice	v0.0.0-20230706085634-23c8f603cac9+dirty	build	-buildmode=exebuild	-compiler=gcbuild	DefaultGODEBUG=asynctimerchan=1,gotestjsonbuildtext=1,gotypesalias=0,httplaxcontentlength=1,httpmuxgo121=1,httpservecontentkeepheaders=1,multipathtcp=0,netedns0=0,panicnil=1,randseednop=0,rsa1024min=0,tls10server=1,tls3des=1,tlsmlkem=0,tlsrsakex=1,tlsunsafeekm=1,winreadlinkvolume=0,winsymlink=0,x509keypairleaf=0,x509negativeserial=1,x509rsacrt=0,x509usepolicies=0build	CGO_ENABLED=1build	CGO_CFLAGS=build	CGO_CPPFLAGS=build	CGO_CXXFLAGS=build	CGO_LDFLAGS=build	GOARCH=amd64build	GOOS=linuxbuild	GOAMD64=v1build	vcs=gitbuild	vcs.revision=23c8f603cac9cde2cf7533287fc2091c37dc024fbuild	vcs.time=2023-07-06T08:56:34Zbuild	vcs.modified=true

对于在线服务，希望将编译信息封装成api便于确认版本。

package mainimport ("fmt""runtime/debug""github.com/gin-gonic/gin"
)func Info(c *gin.Context) {info, ok := debug.ReadBuildInfo()if !ok {c.JSON(500, gin.H{"error": "no build info available"})return}buildInfo := make(map[string]string)for _, setting := range info.Settings {buildInfo[setting.Key] = setting.Value}c.JSON(200, buildInfo)
}func main() {router := gin.Default()router.GET("/info", Info)fmt.Println("Server starting on :8080")router.Run(":8080")
}
