The experimental project to use nghttp2 C library from Go using cgo. Currently, server implementation is available.
First, build and install nghttp2. Do git clone https://github.com/tatsuhiro-t/go-nghttp2.git and enter demo directory. Then run go run demo.go. It fires up HTTP/2 capable https server listening at port 3000. It also supports HTTP/1 connection.
nghttp2.Server only supports https HTTP/2 connection right now.
package main
import (
"github.com/tatsuhiro-t/go-nghttp2"
"io"
"log"
"net/http"
)
func main() {
var srv http.Server
srv.Addr = "localhost:3000"
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
io.WriteString(w, "hello world")
})
// Set up srv so that if HTTP/2 is negotiated in TLS NPN,
// connection is intercepted by nghttp2.Server.
nghttp2.ConfigureServer(&srv, &nghttp2.Server{})
log.Printf("Listening on " + srv.Addr)
log.Fatal(srv.ListenAndServeTLS("server.crt", "server.key"))
}
