在Go語言中實現責任鏈模式的調用步驟如下:
type Handler interface {
SetNext(handler Handler)
HandleRequest(request Request) bool
}
type ConcreteHandler1 struct {
next Handler
}
func (c *ConcreteHandler1) SetNext(handler Handler) {
c.next = handler
}
func (c *ConcreteHandler1) HandleRequest(request Request) bool {
// 處理請求的邏輯
if c.next != nil {
return c.next.HandleRequest(request)
}
return true
}
handler1 := &ConcreteHandler1{}
handler2 := &ConcreteHandler2{}
handler3 := &ConcreteHandler3{}
handler1.SetNext(handler2)
handler2.SetNext(handler3)
request := Request{...}
handler1.HandleRequest(request)
通過以上步驟,就可以實現在Go語言中使用責任鏈模式進行請求處理。
