在Go语言中实现责任链模式的调用步骤如下:
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 {
// 处理请求的逻辑
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)
通过以上步骤,就可以实现在Go语言中使用责任链模式进行请求处理。
