在Golang中使用反射获取函数名称

Question

I'm trying to use Go's reflection system to retrieve the name of a function but I get an empty string when calling the Name method on its type. Is this the expected behavior?

This is a simple example of how I approach the problem:

package main

import "fmt"
import "reflect"

func main() {
    typ := reflect.TypeOf(main)
    name := typ.Name()
    fmt.Println("Name of function" + name)
}

Answer 1

The solution is to use FuncForPc which returns a *Func.

This returns "main.main" :

package main

import "fmt"
import "reflect"
import "runtime"


func main() {
    name := runtime.FuncForPC(reflect.ValueOf(main).Pointer()).Name()
    fmt.Println("Name of function : " + name)
}

If you want "main", just tokenize it.
