go语言gorilla/mux添加favicon.ico

go语言gorilla/mux添加favicon.ico 静态文件

    router = mux.NewRouter()
    router.HandleFunc("/favicon.ico", func(w http.ResponseWriter, r *http.Request) {
        w.Header().Set("Content-Type", "image/x-icon")
        //favicon.ico相对main.go的路径               
        http.ServeFile(w, r, "./favicon.ico")
    }).Methods("GET")

如果页面不展示记得加个参数防止缓存, 0.0坑死

<link rel="icon" type="image/x-icon" href="/favicon.ico?v=2">
