通过Golang提供HTML5应用程序

Question

I recently made a golang application and hosted it on Heroku, and I'd like to serve my HTML5 via the golang net/http router (at "/serv"), The server is working well, but when I type in:

http.ServeFile(w, r, "html/index.html")

The page loads and the name of my html app appears, but the app doesn't load and it basically stays as a black screen.

My html5 application looks like this in (localhost) Here...

And my file directory for the html5 application is Here,,,

You've set up a handler to serve exactly one file, but you apparently don't have anything set up to serve anything other than the file at html/index.html. You probably want to set up a file server for the entire directory:

http.Handle("/", http.FileServer(http.Dir("./html")))
