如何使用Golang Gorilla Mux查找CSS文件

Question

I'm using Go with Gorilla Mux.

This is my webserver.go file

package main

import (
  "log"
  "net/http"

  "github.com/gorilla/mux"
)

func HomeHandler(rw http.ResponseWriter, r *http.Request) {
  http.ServeFile(rw, r, "index.html")
}

func main() {
  r := mux.NewRouter()
  r.HandleFunc("/", HomeHandler)

  http.Handle("/", r)

  log.Println("Server running on :8080")
  err := http.ListenAndServe(":8080", r)
  if err != nil {
     log.Printf("Error: %s
", err.Error())
  }
}

In the same folder where the webserver.go file is located is the index.html file.

/ - here is the index.html

/css - All the CSS files

/images - All the images, resource files

I manage to load the index.html file using the above code but it doesn't seem to load the CSS files and images.

inside the index.html file I have.

<link rel="stylesheet" type="text/css" href="css/demo.css" />
<link rel="stylesheet" type="text/css" href="css/style.css" />
<link rel="stylesheet" type="text/css" href="css/animate-custom.css" />

So it should find the css files or do I have to make sure that "Go" can find the css and image folder? How?

You can use http.FileServer for serving all the static files independently of gorilla/mux.

package main

import (
    "log"
    "net/http"

    "github.com/gorilla/mux"
)

func HomeHandler(rw http.ResponseWriter, r *http.Request) {
    http.ServeFile(rw, r, "index.html")
}

func main() {
    r := mux.NewRouter()

    cssHandler := http.FileServer(http.Dir("./css/"))
    imagesHandler := http.FileServer(http.Dir("./images/"))

    http.Handle("/css/", http.StripPrefix("/css/", cssHandler))
    http.Handle("/images/", http.StripPrefix("/images/", imagesHandler))
    r.HandleFunc("/", HomeHandler)
    http.Handle("/", r)

    log.Println("Server running on :8080")
    log.Fatal(http.ListenAndServe(":8080", nil))
}
