golang web 封装之 handles

封装方式一、将 model 和 handle 以及中间层放在不同的包中

main

router.GET("/new", articles.New)
router.GET("/articles/:_id", articles.Edit)

 handle

func New(c *gin.Context) {
	article := models.Article{}

	c.HTML(http.StatusOK, "articles/form", gin.H{
		"title":   "New article",
		"article": article,
	})
}

model

// Article model
type Article struct {
	Id        bson.ObjectId `json:"_id,omitempty" bson:"_id,omitempty"`
	Title     string        `json:"title" form:"title" binding:"required" bson:"title"`
	Body      string        `json:"body" form:"body" binding:"required" bson:"body"`
	CreatedOn int64         `json:"created_on" bson:"created_on"`
	UpdatedOn int64         `json:"updated_on" bson:"updated_on"`
	// User      bson.ObjectId `json:"user"`
}

middleware 

router.Use(middlewares.Connect)
router.Use(middlewares.ErrorHandler)

封装方式二、将路由函数写好，将参数以参数形式传递给 action

srv.Ws.HandleConnect(func(s *melody.Session) {
	FireConnect(srv, s)
})

还可以封装一个 help函数，一个 log方法

func (a *Action) ToLog(g *Game) {
	PutCards := make([]Card, 0)
	TakeCard := g.CardFromReference(a.TakeCard)
	for _, id := range a.PutCards {
		PutCards = append(PutCards, g.CardFromReference(id))
	}
	g.LastLog = &Log{a.PlayerName, a.Name, TakeCard, PutCards, a.Option}
}
