直接上代码:
package mainimport "fmt"//现在有个屌丝,有个撸管方法,我们的需求是在撸管前后***子穿裤子type diaosi struct {}func (b *diaosi) LUALU() { fmt.Println("EN... A.. A...OH GOD..FUCK ..ME..")}type decorator struct { *diaosi LUALU func()}func decorat(b *diaosi) (d *decorator) { d = &decorator{b, nil} d.LUALU = func() { fmt.Println("take off trousers...") b.LUALU() fmt.Println("take on trousers...") } return}func main() { //吊丝撸啊撸 b := &diaosi{} b.LUALU() fmt.Println("===========") //吊丝 ***子->撸啊撸->穿裤子 c := decorat(b) c.LUALU() //作业:屌丝打开×××->***子->撸啊撸->穿裤子->关××× 怎么实现?}
