go - 使用 JulienSchmidt httprouter 服务 favicon.ico

Question

我可以使用标准的 net/http 包获取 favicon.icon，但在使用 julienschmidt/httprouter 时遇到了问题。这就是我正在尝试的，并且收到 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")
}

Answer 1

我能够通过从 stuff/images/favicon.ico 中删除前导斜杠来解决问题。谢谢@Peter。

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