Iris 允許每個應(yīng)用程序注冊無限數(shù)量的視圖引擎。除此之外，您還可以為每個路由組或通過中間件注冊一個視圖引擎！

// Register a view engine per group of routes.
adminGroup := app.Party("/admin")
adminGroup.RegisterView(iris.Blocks("./views/admin", ".html"))

通過中間件

func middleware(views iris.ViewEngine) iris.Handler {
    return func(ctx iris.Context) {
        ctx.ViewEngine(views)
        ctx.Next()
    }
}

用法

// Register a view engine on-fly for the current chain of handlers.
views := iris.Blocks("./views/on-fly", ".html")
views.Load()

app.Get("/", setViews(views), onFly)
