With the release of Go1.6 and the addition of http2 to the standard library, this package is no longer under active development. It is highly recommended that former users of this package migrate to HTTP/2.
A full-featured SPDY library for the Go language.
Note that this implementation currently supports SPDY drafts 2 and 3.
See these examples for a quick intro to the package.
Note that using this package with Martini is likely to result in strange and hard-to-diagnose bugs. For more information, read this article. As a result, issues that arise when combining the two should be directed at the Martini developers.
The following examples use features specific to SPDY.
Just the handler is shown.
Use SPDY's pinging features to test the connection:
package main
import (
"net/http"
"time"
"github.com/SlyMarbo/spdy"
)
func Serve(w http.ResponseWriter, r *http.Request) {
// Ping returns a channel which will send an empty struct.
if ping, err := spdy.PingClient(w); err == nil {
select {
case response := <- ping:
if response != nil {
// Connection is fine.
} else {
// Something went wrong.
}
case <-time.After(timeout):
// Ping took too long.
}
} else {
// Not SPDY
}
// ...
}Sending a server push:
package main
import (
"net/http"
"github.com/SlyMarbo/spdy"
)
func Serve(w http.ResponseWriter, r *http.Request) {
// Push returns a separate http.ResponseWriter and an error.
path := r.URL.Scheme + "://" + r.URL.Host + "/example.js"
push, err := spdy.Push(path)
if err != nil {
// Not using SPDY.
}
http.ServeFile(push, r, "./content/example.js")
// Note that a PushStream must be finished manually once
// all writing has finished.
push.Finish()
// ...
}
