我很好奇如何从我拥有的中间件设置模板变量，这是我的中间件：func IsUserLoggedIn(router http.Handler) http.Handler { return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) { log.Println("Checking if user is logged in") session, err := store.Get(r, "loggedIn") if err != nil { http.Error(w, err.Error(), 500) return } // Perform some If Statements and set True/False // Set Session Variables session.Values["isLoggedIn"] = true // Save Session session.Save(r, w) // Set Template Variable router.ServeHTTP(w, r) })}然后在我的主要布局模板中：{{ define "layout" }}<!DOCTYPE html><html> <head> <meta charset="UTF-8"> <meta name="description" content=""> <meta name="keywords" content=""> <meta name="author" content=""> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css"> <link rel="stylesheet" href="/static/css/main.css"> <title> {{ .Title }} </title> </head> <body> {{ SET SOMETHING HERE TO SAY YOU'RE LOGGED IN }} {{ GET THE SESSION VARIABLE AND SET ACCORDINGLY }} {{ template "body" .}} </body></html>{{ end }}基本上如何访问模板中的会话变量？
