类使用:实现一个people中有一个sayhi的方法调用功能,代码如下:
type People struct { //.. } func (p *People) SayHi() { fmt.Println("************************* say hi !!") } func (this *LoginController) Get() { p := new(People) p.SayHi() this.TplName = "login.html" }
接口使用:实现上面功能,代码如下:
type People struct { //.. } func (p *People) SayHi() { fmt.Println("************************* say hi !!") } type IPeople interface { SayHi() } func (this *LoginController) Get() { var p IPeople = new(People) p.SayHi() this.TplName = "login.html" }
