golang实现路由中间件middleware

  registerHandlers.go

  package router

  import (

  "../ctrl"

  "../funcs"

  "github.com/julienschmidt/httprouter"

  "net/http"

  )

  type middleWareHandler struct {

  r *httprouter.Router

  }

  func NewMiddleWareHandler(r *httprouter.Router) http.Handler {

  m := middleWareHandler{}

  m.r = r

  return m

  }

  func (m middleWareHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {

  //检验合法性(session)

  ok := funcs.ValidateUser(r)

  if ok == false {

  funcs.Resp(w, -1, "请先登录", nil)

  return

  }

  m.r.ServeHTTP(w, r)

  }

  func RegisterHandlers() *httprouter.Router {

  router := httprouter.New()

  router.ServeFiles("/asset/*filepath", http.Dir("asset")) //启动静态资源服务

  router.POST("/user/login", ctrl.Login) //登陆

  router.POST("/user/register", ctrl.Register) //注册

  router.POST("/contact/addfriend", ctrl.AddFriend) //添加好友

  router.POST("/contact/loadfriend", ctrl.LoadFriend) //加载好友

  return router

  }

  main.go

  package main

  import (

  "./funcs"

  "./router"

  "html/template"

  "log"

  "net/http"

  "runtime"

  )

  var (

  AllConf funcs.Confs

  err error

  tpl *template.Template

  //SessionManager *funcs.Manager

  )

  //func init() {

  // SessionManager = funcs.Manager{}

  //}

  //循环渲染所有模版、路由方法

  func DisplayView() {

  tpl, err = template.ParseGlob("view/**/*")

  //错误则不必再继续

  if err != nil {

  log.Fatal(err.Error())

  }

  for _, v := range tpl.Templates() {

  tplName := v.Name()

  http.HandleFunc(tplName, func(writer http.ResponseWriter, request *http.Request) {

  tpl.ExecuteTemplate(writer, tplName, nil)

  })

  }

  }

  func main() {

  //初始化配置

  if AllConf, err = funcs.InitConf("config.json"); err != nil {

  log.Fatal(err)

  }

  //初始化核心数

  runtime.GOMAXPROCS(runtime.NumCPU())

  //初始化数据库

  //渲染模版

  //DisplayView()

  //注册路由

  r := router.RegisterHandlers()

  mh := router.NewMiddleWareHandler(r)

  err := http.ListenAndServe(":80", mh)

  if err != nil {

  log.Fatal(err)

  }

  }

  还可以更灵活:

  main.go

  package main

  import (

  "./funcs"

  "html/template"

  "log"

  "net/http"

  "runtime"

  "./ctrl"

  )

  var (

  AllConf funcs.Confs

  err error

  tpl *template.Template

  //SessionManager *funcs.Manager

  )

  //func init() {

  // SessionManager = funcs.Manager{}

  //}

  //循环渲染所有模版、路由方法

  func DisplayView() {

  tpl, err = template.ParseGlob("view/**/*")

  //错误则不必再继续

  if err != nil {

  log.Fatal(err.Error())

  }

  for _, v := range tpl.Templates() {

  tplName := v.Name()

  http.HandleFunc(tplName, func(writer http.ResponseWriter, request *http.Request) {

  tpl.ExecuteTemplate(writer, tplName, nil)

  })

  }

  }

  func main() {

  //初始化配置

  if AllConf, err = funcs.InitConf("config.json"); err != nil {

  log.Fatal(err)

  //初始化核心数

  runtime.GOMAXPROCS(runtime.NumCPU())

  //初始化数据库

  http.Handle("/user/login", http.HandlerFunc(ctrl.Login)) //登陆 post

  http.Handle("/user/register", http.HandlerFunc(ctrl.Register)) //注册 post

  http.Handle("/contact/addfriend", funcs.AuthLogin(http.HandlerFunc(ctrl.AddFriend))) //添加好友 get

  http.Handle("/contact/loadfriend", funcs.AuthLogin(http.HandlerFunc(ctrl.LoadFriend))) //加载好友 get

  err := http.ListenAndServe(":80", nil)

  if err != nil {

  log.Fatal(err)

  }

  }

  )

  //验证是否登陆

  func AuthLogin(next http.Handler) http.Handler {

  return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {

  //验证...

  })

  }

  ctrl/addFriend.go

  package ctrl

  import (

  "../funcs"

  var contactModel model.Contact
