How do I serve static css files in go (go version go1.9.1 linux/amd64)?
My present code doesn't work (it does show website but it does not see css). Here is my attempt to use standard file serving using go handler. When I go into page source and click link to css/styles.css it appears it is visible and redirects correctly (is under correct url). I presume I lack knowledge about some step of parsing.
package main
import (
"html/template"
"net/http"
"fmt"
)
const (
PORT = ":3000"
HOST = "localhost"
)
func handleBooks(w http.ResponseWriter, r *http.Request) {
tmpl := template.Must(template.ParseFiles("books.html"))
tmpl.Execute(w)
}
func main() {
fs := http.FileServer(http.Dir("css"))
http.Handle("/css/", http.StripPrefix("/css/", fs))
http.HandleFunc("/books", handleBooks)
fmt.Println("Listening on " + HOST + PORT)
http.ListenAndServe(PORT, nil)
}
style.css
.body {
margin-left: auto;
margin-right: auto;
width: 1000px;
}
books.html
<html>
<head>
<title>Books</title>
<link rel="stylesheet" href="css/style.css" type="text/css">
</head>
<body>
<ul>
books
<li>book1</li>
<li>book2</li>
</ul>
</body>
</html>
My directory tree:
- src:
- books.html
- main.go
- css
- style.css
It seems that the problem was with this part:
fs := http.FileServer(http.Dir("css"))
http.Handle("/css/", http.StripPrefix("/css/", fs))
After I cleared cache it turned out that the slash in the first argument of http.Handle is necessary. Big thanks to mkopriva, without you I wouldn't have checked it.
