README

⚠️ We have no plans to maintain our set of fixes for this package, and it seems the original project is no longer being maintained... (as of 14th May 2023).

HTTP2

http2 is an implementation of HTTP/2 protocol for fasthttp.

This repository is an attempt to fix some of the shortcomings we personally encountered whilst using the library as the parent repository seems to be abandoned. No support is provided when using this library, whilst we are using it internally, there are no guarantees that this will work perfectly with your implementation.

How to use the server?

The server can only be used if your server supports TLS. Then, you can call ConfigureServer.

package main

import (
	"github.com/valyala/fasthttp"
	"github.com/dgrr/http2"
)

func main() {
    s := &fasthttp.Server{
        Handler: yourHandler,
        Name:    "HTTP2 test",
    }

    http2.ConfigureServer(s, http2.ServerConfig{})
    
    s.ListenAndServeTLS(...)
}

How to use the client?

The HTTP/2 client only works with the HostClient.

package main

import (
        "fmt"
        "log"

        "github.com/dgrr/http2"
        "github.com/valyala/fasthttp"
)

func main() {
        hc := &fasthttp.HostClient{
                Addr:  "api.binance.com:443",
        }

        if err := http2.ConfigureClient(hc, http2.ClientOpts{}); err != nil {
                log.Printf("%s doesn't support http/2\n", hc.Addr)
        }

        statusCode, body, err := hc.Get(nil, "https://api.binance.com/api/v3/time")
        if err != nil {
                log.Fatalln(err)
        }

        fmt.Printf("%d: %s\n", statusCode, body)
}

type Server 

type Server struct {
	// contains filtered or unexported fields
}

Server defines an HTTP/2 entity that can handle HTTP/2 connections.

func ConfigureServer 

func ConfigureServer(s *fasthttp.Server, cnf ServerConfig) *Server

ConfigureServer configures the fasthttp server to handle HTTP/2 connections. The HTTP/2 connection can be only established if the fasthttp server is using TLS.

Future implementations may support HTTP/2 through plain TCP.

This package currently supports the following fasthttp.Server settings:

  • Handler: Obviously, the handler is taken from the Server.
  • ReadTimeout: Will cancel a stream if the client takes more than ReadTimeout to send a request. This option NEVER closes the connection.
  • IdleTimeout: Will close the connection if the client doesn't send a request within the IdleTimeout. This option ignores any PING/PONG mechanism. To disable the option you can set it to zero. No value is taken by default, which means that by default ALL connections are open until either endpoint closes the connection.

func ConfigureServerAndConfig 

func ConfigureServerAndConfig(s *fasthttp.Server, tlsConfig *tls.Config) *Server

ConfigureServerAndConfig configures the fasthttp server to handle HTTP/2 connections and your own tlsConfig file. If you are NOT using your own tls config, you may want to use ConfigureServer.
