使用favicon.ico httprouter为JulienSchmidt服务

Question

我可以用标准的favicon.icon包获得net/http，但是julienschmidt/httprouter有问题。这就是我正在尝试的，并且收到了favicon.ico文件的404错误。

import (
    "github.com/julienschmidt/httprouter"
    "net/http"
    "log"
)

func main(){
    router := httprouter.New()
    router.GET("/", index)
    router.POST("/", login)
    router.GET("/logout", logout)
    router.GET("/favicon.ico", faviconHandler)
    router.ServeFiles("/stuff/*filepath", http.Dir("stuff"))
    log.Fatal(http.ListenAndServe(":8080", router))
}

func faviconHandler(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
     http.ServeFile(w, r, "/stuff/images/favicon.ico")
}

我能够通过从stuff/images/favicon.ico中删除前面的斜杠来解决这个问题。谢谢彼得。
