一、参考
golang学习系列目录——更新ing
goid
二、根本应用
获取以后运行 goroutine的id
2.1 装置
GO111MODULE=on go get -u github.com/petermattis/goid
2.2 示例
1 package sync1 2 3 import ( 4 "fmt" 5 "runtime" 6 "strconv" 7 "strings" 8 "testing" 9 10 "github.com/petermattis/goid" 11 ) 12 13 func TestGetGoID(t *testing.T) { 14 15 var buf [64]byte 16 n := runtime.Stack(buf[:], false) 17 idField := strings.Fields(strings.TrimPrefix(string(buf[:n]), "goroutine "))[0] 18 id, err := strconv.Atoi(idField) 19 if err != nil { 20 panic(fmt.Sprintf("can not get goroutine id: %v", err)) 21 } 22 fmt.Println("get goroutine id: ", id) 23 } 24 25 func TestGetGoID2(t *testing.T) { 26 gid := goid.Get() 27 fmt.Println("get goroutine id is ", gid) 28 }
