gorilla的session怎么在别的函数接受session

package main import ( "github.com/gorilla/sessions" "net/http" "os" ) var store sessions.Store // var store = sessions.NewCookieStore([]byte("something-very-secret")) var abc string func pageHandler(w http.ResponseWriter, r *http.Request) { session, _ := store.Get(r, "get_name_session") Name := session.Values["name"].(string) session.Values["name"] = "Dean" session.Save(r, w) println("操作数据库成功2！") println(string(Name)) } func UserValid(w http.ResponseWriter, r *http.Request) { } func main() { store = sessions.NewCookieStore([]byte(os.Getenv("KEY"))) http.HandleFunc("/", pageHandler) http.ListenAndServe(":7888", nil) } 怎么在UserValid这个函数接受在pageHandler定义的session的值？求大神解答
