How can I enable gzip compression using the gzip middleware of the go-chi framework?
Try using the example shown here:
https://github.com/go-chi/chi/issues/204
but when I check with curl, I get this:
$ curl -H "Accept-Encoding: gzip" -I http://127.0.0.1:3333
HTTP/1.1 405 Method Not Allowed

I tried the code "hello world":
package main
import (
"net/http"
"github.com/go-chi/chi"
"github.com/go-chi/chi/middleware"
)
func main() {
r := chi.NewRouter()
r.Use(middleware.RequestID)
r.Use(middleware.Logger)
//r.Use(middleware.DefaultCompress) //using this produces the same result
r.Use(middleware.Compress(5, "gzip"))
r.Get("/", Hello)
http.ListenAndServe(":3333", r)
}
func Hello(w http.ResponseWriter, r *http.Request){
w.Header().Set("Content-Type", "text/html") //according to the documentation this must be here to enable gzip
w.Write([]byte("hello world\n"))
}
but when I try to verify with curl, the result is the same
$ curl -H "Accept-Encoding: gzip" -I http://127.0.0.1:3333
HTTP/1.1 405 Method Not Allowed

what's going on?
Use the commented middleware.DefaultCompress
and a normal GET
request.
package main
import (
"net/http"
"github.com/go-chi/chi"
"github.com/go-chi/chi/middleware"
)
func main() {
r := chi.NewRouter()
r.Use(middleware.RequestID)
r.Use(middleware.Logger)
r.Use(middleware.DefaultCompress)
r.Get("/", Hello)
http.ListenAndServe(":3333", r)
}
func Hello(w http.ResponseWriter, r *http.Request) {
w.Header().Set("Content-Type", "text/html")
w.Write([]byte("hello world\n"))
}
Try with curl
:
$ curl -v http://localhost:3333 --compressed

Or HTTPie
