net/http: support "gzip" as a Transfer Encoding

What version of Go are you using (go version)?

go version go1.10.3 windows/amd64

Does this issue reproduce with the latest release?

Yes.

What operating system and processor architecture are you using (go env)?

set GOARCH=amd64 set GOBIN= set GOCACHE=C:\Users\xxxx\AppData\Local\go-build set GOEXE=.exe set GOHOSTARCH=amd64 set GOHOSTOS=windows set GOOS=windows set GOPATH=C:\Users\xxxx\go set GORACE= set GOROOT=C:\Go set GOTMPDIR= set GOTOOLDIR=C:\Go\pkg\tool\windows_amd64 set GCCGO=gccgo set CC=gcc set CXX=g++ set CGO_ENABLED=1 set CGO_CFLAGS=-g -O2 set CGO_CPPFLAGS= set CGO_CXXFLAGS=-g -O2 set CGO_FFLAGS=-g -O2 set CGO_LDFLAGS=-g -O2 set PKG_CONFIG=pkg-config set GOGCCFLAGS=-m64 -mthreads -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=C:\Users\xxxx\AppData\Local\Temp\go-build557436246=/tmp/go-build -gno-record-gcc-switches

What did you do?

I am requesting a URL with code below:

package main

import (
	"fmt"
	"net/http"
	"time"
)

func main() {

	
	urlReq2 := "https://www.azulseguros.com.br/azul-cms/wp-content/themes/azul2016/integracao-azul-leve.php?timestamp=NGJYHX7MXNS"
	req, err := http.NewRequest("GET", urlReq2, nil)
	netClient := &http.Client{
		Timeout: time.Second * 10,
	}
	_, err = netClient.Do(req)
	if err != nil {
		fmt.Println(err)
	}

	

}

I got this error: net/http: HTTP/1.x transport connection broken: unsupported transfer encoding "gzip"

What did you expect to see?

I expect to be foward to other page and get HTML. In other languages like nodejs and c#, the same request is OK. Running cURL also bring me the result.

What did you see instead?

Error on netClient.Do(): net/http: HTTP/1.x transport connection broken: unsupported transfer encoding "gzip"
