golang中接口类型小案例

1.  在项目中实现注册成功之后，向用户发送邮件、微信提醒

package main

import "fmt"

type IMessage interface {
	send() bool
}

type Email struct {
	email string
	content string
}
func (e *Email) send() bool {
	fmt.Println("发送邮件提醒：", e.email, e.content)
	return true
}

type Wechat struct {
	wid int
	content string
}
func (w *Wechat) send() bool {
	fmt.Println("发送微信提醒：", w.wid, w.content)
	return true
}

func DoSomething(messageSlice []IMessage) {
	for _, item := range messageSlice {
		ret := item.send()
		fmt.Println(ret)
	}
}

func main() {
	// 在项目中实现注册成功之后，向用户发送邮件、微信提醒
	messageSlice := []IMessage{
		&Email{email: "1341935532@qq.com", content: "邮件提醒"},
		&Wechat{wid: 110, content: "微信提醒"},
	}
	DoSomething(messageSlice)
}
