我使用 Gorilla 会话（通过 negroni-sessions）将我的用户会话存储在 cookie 中。我也github.com/unrolled/render用于我的 HTML 模板渲染：
main.go：
package main
import (
...
"github.com/codegangsta/negroni"
"github.com/goincremental/negroni-sessions"
"github.com/goincremental/negroni-sessions/cookiestore"
"github.com/julienschmidt/httprouter"
"github.com/unrolled/render"
...
)
func init() {
...
ren = render.New(render.Options{
Directory: "templates",
Layout: "layout",
Extensions: []string{".html"},
Funcs: []template.FuncMap{TemplateHelpers},
IsDevelopment: false,
})
...
}
func main() {
...
router := httprouter.New()
router.GET("/", HomeHandler)
// Add session store
store := cookiestore.New([]byte("my password"))
store.Options(sessions.Options{
//MaxAge: 1200,
Domain: "",
Path: "/",
})
n := negroni.New(
negroni.NewRecovery(),
sessions.Sessions("cssession", store),
negroni.NewStatic(http.Dir("../static")),
)
n.UseHandler(router)
n.Run(":9000")
}
正如你在上面看到的，我使用了一个layout.html主 HTML 模板，它包含在任何页面呈现时，比如我的主页：
package main
import (
"html/template"
"github.com/julienschmidt/httprouter"
)
func HomeHandler(w http.ResponseWriter, r *http.Request, p httprouter.Params) {
var model = struct {
CatalogPicks []PromotionalModelList
ClearanceItems []Model
}{
CatalogPicks: GetCatalogPicks(),
ClearanceItems: GetClearanceItems(),
}
ren.HTML(w, http.StatusOK, "home", model)
}
在我的layout.html主 HTML 模板中，我想呈现一个管理菜单，但前提是当前用户是管理员：
布局.html：
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>{{ template "title" . }}</title>
...
</head>
<body>
