Go语言接口实现动态调用函数示例

import "fmt"

type A interface { aaa(ss string) }

type a struct{}

func (a *a) aaa(ss string) { fmt.Println('函数1' + ss) }

type b struct{}

func (b *b) aaa(ss string) { fmt.Println('函数2' + ss) }

func callAaa(name string, ss string) { var obj A if name == "a" { obj = &a{} } else if name == "b" { obj = &b{} } else { fmt.Println("无效的参数: ", name) return } obj.aaa(ss) }

// 调用方式： callAaa("a", "hello") callAaa("b", "world") callAaa("c", "oops") // 输出无效的参数: c
