我如何获取方法参数名

Question

我有这个漂亮的功能，打印有关给定类型的给定方法的一些信息，这里是一个goplay

它所有我需要的只是我不能找到一种方法获取方法参数名称，任何想法来实现？

func AnalyzeMethod(instance interface {},methodName string){ 
     m,ok := reflect.ValueOf(instance).Type().MethodByName(methodName) 
    if ok{ 
     isVariadic := m.Type.IsVariadic() 
     var VariadicIndex int 
     var VariadicType reflect.Type 
     var FirstPositionalIndex int 
     var LastPositionalIndex int 
     var ArgsLength int = m.Type.NumIn()-1 
     //var []string ArgumentNames //can't find a way to get an ordered slice of names of every argument that the function takes 

     if ArgsLength>0{ 
     FirstPositionalIndex = 1 
     } 


     if isVariadic{ 
     VariadicIndex = ArgsLength 
     VariadicType = m.Type.In(VariadicIndex) 
     LastPositionalIndex = ArgsLength-1 
     } else { 
     VariadicIndex = -1 
     LastPositionalIndex = ArgsLength 
     } 

     fmt.Println("ArgsLength:",ArgsLength)  
     fmt.Println("FirstPositionalIndex:",FirstPositionalIndex) 
     fmt.Println("LastPositionalIndex:",LastPositionalIndex) 
     fmt.Println("Variadic:",isVariadic) 
     fmt.Println("VariadicIndex:",VariadicIndex) 
     fmt.Println("VariadicType:",VariadicType) 
     fmt.Println("ArgumentNames","How?") 

     } 
}

局部变量的名称（包括函数参数）仅供程序员使用;编译器会在生成代码时丢弃它们。没有办法检索参数名称，因为它们在编译的代码中不可用。
