Serve is a very simple static file server in go | |
Usage: | |
-p="8100": port to serve on | |
-d=".": the directory of static files to host | |
Navigating to http://localhost:8100 will display the index.html or directory | |
listing file. | |
*/ | |
package main | |
import ( | |
"flag" | |
"log" | |
"net/http" | |
) | |
func main() { | |
port := flag.String("p", "8100", "port to serve on") | |
directory := flag.String("d", ".", "the directory of static file to host") | |
flag.Parse() | |
http.Handle("/", http.FileServer(http.Dir(*directory))) | |
log.Printf("Serving %s on HTTP port: %s\n", *directory, *port) | |
log.Fatal(http.ListenAndServe(":"+*port, nil)) | |
} |
It's weird that this exists. I was tired of using python3 -m http.server and decided to create my own. After, I googled to see what's out there, and alas!!
package main
import (
"flag"
"log"
"net/http"
"path/filepath"
)
var (
path = flag.String("path", ".", "path to the folder to serve. Defaults to the current folder")
port = flag.String("port", "8080", "port to serve on. Defaults to 8080")
)
func main() {
flag.Parse()
dirname, err := filepath.Abs(*path)
if err != nil {
log.Fatalf("Could not get absolute path to directory: %s: %s", dirname, err.Error())
}
log.Printf("Serving %s on port %s", dirname, *port)
err = Serve(dirname, *port)
if err != nil {
log.Fatalf("Could not serve directory: %s: %s", dirname, err.Error())
}
}
func Serve(dirname string, port string) error {
fs := http.FileServer(http.Dir(dirname))
http.Handle("/", fs)
return http.ListenAndServe(":"+port, nil)
}
Thanks!
Thanks
Am glad you found it useful
Hi, I've added base URL as flag in this link
Thanks!
Does anybody happen to know why browsers try to display the old directory listing, even though the server is now launched from a different directory?
It's the same on my firefox on Linux machine and chrome on my android. If I reopen the page it'll show the old listing, even though it gets 404 if files are accessed. If I open in incognito or new browser, everything is fine and the new listing is loaded.
