Serving gzipped content for Go

Question

I\'m starting to write server-side applications in Go. I\'d like to use the Accept-Encoding request header to determine whether to compress the response entity usi

Answer 1

The New York Times have released their gzip middleware package for Go.

You just pass your http.HandlerFunc through their GzipHandler and you're done. It looks like this:

package main

import (
    "io"
    "net/http"
    "github.com/nytimes/gziphandler"
)

func main() {
    withoutGz := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        w.Header().Set("Content-Type", "text/plain")
        io.WriteString(w, "Hello, World")
    })

    withGz := gziphandler.GzipHandler(withoutGz)

    http.Handle("/", withGz)
    http.ListenAndServe("0.0.0.0:8000", nil)
}
