http http1.1ssl http2 http3 server only exemple

[itwars]

Hi,
You really do a GREAT JOB!

My goal is to have:

1. a http to https redirect (can't figure out how to do it)
2. a http2 + http3 server (I can't figure out even by reading the example provide in markdown file)

package main

import (
	"crypto/tls"
	"os"
	"regexp"
	"time"

	"github.com/vicanso/elton"
	"github.com/vicanso/elton/middleware"
)

func getCert() (cert []byte, key []byte, err error) {
	cert, err = os.ReadFile("server.crt")
	if err != nil {
		return
	}
	key, err = os.ReadFile("server.key")
	if err != nil {
		return
	}
	return
}

func main() {
	e2 := elton.New()
	// Gzip + Br compression
	cfgCompress := middleware.NewCompressConfig(new(middleware.GzipCompressor), new(middleware.BrCompressor))
	// Br compression only
	//cfgCompress := middleware.NewCompressConfig(new(middleware.BrCompressor))
	cfgCompress.Checker = regexp.MustCompile("svg|text|javascript|json|html|css|xml")
	e2.Use(middleware.NewCompress(cfgCompress))
	cert, key, err := getCert()
	if err != nil {
		panic(err)
	}
	tlsConfig := &tls.Config{}
	tlsConfig.Certificates = make([]tls.Certificate, 1)
	tlsConfig.Certificates[0], err = tls.X509KeyPair(cert, key)
	if err != nil {
		panic(err)
	}
	e2.Server.TLSConfig = tlsConfig
	sf := new(middleware.FS)
	e2.GET("/", func(c *elton.Context) (err error) {
		r, err := sf.NewReader("static" + "/index.html")
		if err != nil {
			return
		}
		c.SetContentTypeByExt(".html")
		c.Body = r
		return
	})
	e2.GET("/*", middleware.NewStaticServe(sf, middleware.StaticServeConfig{
		Path:             "static",
		MaxAge:           365 * 24 * time.Hour,
		SMaxAge:          time.Hour,
		DenyDot:          true,
		EnableStrongETag: true,
	}))
	err = e2.ListenAndServeTLS(":443", "", "")
	if err != nil {
		panic(err)
	}
	
}

Could you help me?
Thanks.

1. You can use like this:

package main

import (
	"bytes"
	"fmt"

	"github.com/vicanso/elton"
)

func main() {
	e := elton.New()

	e.Use(func(ctx *elton.Context) error {
		// is http
		if ctx.Request.TLS == nil {
			ctx.Redirect(301, "https://yourhost"+ctx.Request.RequestURI)
			return nil
		}
		return ctx.Next()
	})

	e.GET("/ping", func(ctx *elton.Context) error {
		ctx.BodyBuffer = bytes.NewBufferString("pong")
		return nil
	})
	e.ALL("/*", func(ctx *elton.Context) error {
		return nil
	})

	// http 80
	go func() {
		err := e.ListenAndServe(":80")
		fmt.Println(err)
	}()

	// https 443
	err := e.ListenAndServeTLS(":443", "", "")
	fmt.Println(err)
}

2. Do you try this example, htt2_http3

[itwars]

Sorry for my late answer.

1. Your above code give me an error on open ?
2. Issue with golang and http3 version on build...

Question 1:

Please use the cert file and key file for tls:

	err := e.ListenAndServeTLS(":443", certFile, keyFile)

Question 2, please show me more information.
