我正在嘗試在 Google 的應用程序引擎上部署簡單的 go 語言代碼。這是我試圖部署的代碼。 https://github.com/GoogleCloudPlatform/golang-samples/tree/master/appengine/go11x/static主程序package mainimport (    "fmt"    "html/template"    "log"    "net/http"    "os"    "path/filepath"    "time")var (    indexTmpl = template.Must(        template.ParseFiles(filepath.Join("templates", "index.html")),    ))func main() {    http.HandleFunc("/", indexHandler)    // Serve static files out of the public directory.    // By configuring a static handler in app.yaml, App Engine serves all the    // static content itself. As a result, the following two lines are in    // effect for development only.    public := http.StripPrefix("/public", http.FileServer(http.Dir("public")))    http.Handle("/public/", public)    port := os.Getenv("PORT")    if port == "" {        port = "8080"        log.Printf("Defaulting to port %s", port)    }    log.Printf("Listening on port %s", port)    log.Fatal(http.ListenAndServe(fmt.Sprintf(":%s", port), nil))}// indexHandler uses a template to create an index.html.func indexHandler(w http.ResponseWriter, r *http.Request) {    if r.URL.Path != "/" {        http.NotFound(w, r)        return    }    type indexData struct {        Logo        string        Style       string        RequestTime string    }    data := indexData{        Logo:        "/public/gcp-gopher.svg",        Style:       "/public/style.css",        RequestTime: time.Now().Format(time.RFC822),    }    if err := indexTmpl.Execute(w, data); err != nil {        log.Printf("Error executing template: %v", err)        http.Error(w, "Internal server error", http.StatusInternalServerError)    }}問題：如何處理我希望應用程序讀取的模板和其他小文件？我的應用程序是一個玩具應用程序，因此我不需要云存儲或任何此類解決方案。我只想從（本地）目錄中讀取內容。
