前言

package component

组件

定义

 //Component 组件的接口 type Component interface { 
    Init() AfterInit() BeforeShutdown() Shutdown() } // base 是基本的，默认的实现 type Base struct{ 
   } // Init was called to initialize the component. func (c *Base) Init() { 
   } // AfterInit was called after the component is initialized. func (c *Base) AfterInit() { 
   } // BeforeShutdown was called before the component to shutdown. func (c *Base) BeforeShutdown() { 
   } // Shutdown was called to shutdown the component. func (c *Base) Shutdown() { 
   } //Option options struct { 
    name string // component name nameFunc func(string) string // rename handler name schedName string // schedName name } // Option used to customize handler 对options结构体进行设置的函数模板 Option func(options *options) type CompWithOptions struct { 
    Comp Component Opts []Option //对options进行设置的函数组 } type Components struct { 
    comps []CompWithOptions }

方法

1. 注册

// Register registers a component to hub with options func (cs *Components) Register(c Component, options ...Option) { 
    cs.comps = append(cs.comps, CompWithOptions{ 
   c, options}) }

2.获取组件列表

// List returns all components with it's options func (cs *Components) List() []CompWithOptions { 
    return cs.comps }

举个例子demo

//demo.go package demo import ( "github.com/lonng/nano/component" "github.com/lonng/nano/session" "log" ) type Demo struct { 
    component.Base sq int64 } func newDemo() *Demo { 
    return &Demo{ 
   } } func (ds *Demo) Dprint(s *session.Session, msg []byte) error { 
    log.Println("hello,Demo!") return nil }

//demo_init.go package demo var ( // All services in master server Services = &component.Components{ 
   } demoService = newdemoService() ) func init() { 
    Services.Register(demoService ) }

// main.go package main import ( "github.com/lonng/nano" "github.com/lonng/nano/examples/myDemo/demo" ) func main() { 
    listen := "127.0.0.1:10000" nano.Listen(listen, nano.WithMaster(), nano.WithComponents(demo.Services), nano.WithDebugMode(), ) }

执行后的结构：
在这里插入图片描述

在编译的时候出现个问题：
type Demo struct{}
结构名称要大写，否则编译不过去。

下一章继续关于组件的讨论，组件会变成服务，而服务提供具体方法

今天的文章 go开源网络库nano（8)-组件分享到此就结束了，感谢您的阅读。
