Golang提供css文件的正确文件路径

I have been reading and trying to serve css css files to my html page and nothing has been working . I have been reading this https://forum.golangbridge.org/t/serving-static-css-files/2051/10 to get a better understanding . My project structure is below

func WebRoutes(r *mux.Router) {
    r.HandleFunc("/", Index)

   // Trying to serve file here and it's not working
    r.Handle("/web/content/desktop/", http.StripPrefix("/web/content/desktop/", http.FileServer(http.Dir("desktop"))))

   // Below is the correct path since it finds the file
    _, err := os.Stat(filepath.Join(".", "/web/content/desktop/", "page.css"))
     if err != nil {
        println(err.Error())
     }

}

I am referencing the file from my html page like this

 <link rel="stylesheet" type="text/css" href="/Web/Content/desktop/page.css">

Any suggestions would be great since I can't seem to get my CSS to work .

You're serving your static files with:

http.FileServer(http.Dir("desktop"))

But based on the screenshot the path on disk is not "desktop" but rather "Web/Content/desktop".

Keep in mind that given that you're already using StripPrefix, there's no reason to use the full path unless you want to. You could do:

r.Handle("/css/", http.StripPrefix("/css/", http.FileServer(http.Dir("web/content/desktop"))))

Which would change the URL to:

 <link rel="stylesheet" type="text/css" href="/css/page.css">
