通过Reflection实现接口

package main

import (
    "fmt"
    "reflect"
)

type MyInterface interface {
    MyMethod() string
}

type MyType struct {
    Value string
}

func (mt *MyType) MyMethod() string {
    return mt.Value
}

func main() {
    obj := &MyType{Value: "Hello, world!"}
    myInterface := obj.(MyInterface)
    fmt.Println(myInterface.MyMethod())

    reflectObj := reflect.ValueOf(obj)
    reflectMethod := reflectObj.MethodByName("MyMethod")
    fmt.Println(reflectMethod.Call([]reflect.Value{}))
}

Hello, world!
[Hello, world!]
