import "github.com/php2go/netpollmux"

func main() {
	var handler = &netpoll.DataHandler{
		NoShared:   true,
		NoCopy:     true,
		BufferSize: 1024,
		HandlerFunc: func(req []byte) (res []byte) {
			res = req
			return
		},
	}
	if err := netpoll.ListenAndServe("tcp", ":9999", handler); err != nil {
		panic(err)
	}
}

TLS Example

import (
	"crypto/tls"
	"github.com/php2go/netpollmux/internal/socket"
	"github.com/php2go/netpollmux/netpoll"
	"net"
)

func main() {
	var handler = &netpoll.DataHandler{
		NoShared:   true,
		NoCopy:     true,
		BufferSize: 1024,
		HandlerFunc: func(req []byte) (res []byte) {
			res = req
			return
		},
	}
	handler.SetUpgrade(func(conn net.Conn) (net.Conn, error) {
		tlsConn := tls.Server(conn, socket.DefalutTLSConfig())
		if err := tlsConn.Handshake(); err != nil {
			return nil, err
		}
		return tlsConn, nil
	})
	if err := netpoll.ListenAndServe("tcp", ":9999", handler); err != nil {
		panic(err)
	}
}

Websocket Example

package main

import (
	"github.com/php2go/netpollmux/internal/websocket"
	"github.com/php2go/netpollmux/netpoll"
	"net"
)

func main() {
	var handler = &netpoll.ConnHandler{}
	handler.SetUpgrade(func(conn net.Conn) (netpoll.Context, error) {
		return websocket.Upgrade(conn, nil)
	})
	handler.SetServe(func(context netpoll.Context) error {
		ws := context.(*websocket.Conn)
		msg, err := ws.ReadMessage()
		if err != nil {
			return err
		}
		return ws.WriteMessage(msg)
	})
	if err := netpoll.ListenAndServe("tcp", ":9999", handler); err != nil {
		panic(err)
	}
}

		pp := req.URL.Query()
		logger.Info("query params：", params, pp)
		mux.JSON(w, req, []string{"hello world"}, http.StatusOK)
	})
