Transparently decompress http.Server requests and compress responses with gzip and deflate.
Contrary to many cheap solutions you can find on Q&A sites, this library gives you:
- Both compressing and decompressing wrappers for
http.Handler - No compression for responses under 512 bytes
http.ResponseWriterusinghttp.DetectContentTypeon a full 512-byte chunk of initial uncompressed data (not only the first written chunk)http.ResponseWriterimplementinghttp.Flusher, preservinghttp.CloseNotifierandhttp.Hijackerinterfaces- No empty archives being sent on responses with no body
package main
import (
"fmt"
"io/ioutil"
"log"
"net/http"
"github.com/tg/httpzip"
)
func main() {
// Handler reads and writes uncompressed data, as usual
h := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
body, err := ioutil.ReadAll(r.Body)
log.Printf("%q (err: %v)", body, err)
fmt.Fprint(w, "understood!")
})
// httpzip handlers will transparently (de)compress data
http.Handle("/nothing", h)
http.Handle("/compress", httpzip.NewResponseHandler(h))
http.Handle("/decompress", httpzip.NewRequestHandler(h))
http.Handle("/both", httpzip.NewHandler(h))
log.Fatal(http.ListenAndServe(":8080", nil))
// Or you can wrap your ServeMux to enable (de)compression for all handlers at once:
// http.ListenAndServe(":8080", httpzip.NewHandler(http.DefaultServeMux))
