udp_to_ws

udp_to_ws provides udp data over websocket

Usage

Connect to a UDP source

conn := ConnectUDP("localhost:20777")

Implement the handler interface

The UdpWebSocket method needs to be implemented

type socketHandlers struct {
	conn *net.UDPConn
}

func (h *socketHandlers) UdpWebSocket(c *websocket.Conn, w http.ResponseWriter, r *http.Request) {
	packetData := make([]byte, 4*10) // 10 bytes
	extraData := make([]byte, 5*10) // 5 bytes
	ReadUDP(h.conn, packetData, extraData)

	c.WriteMessage(websocket.BinaryMessage, packetData)
}

Start the server

handlers := &socketHandlers{
	conn: conn,
}
StartServer(handlers)

Functions

func ConnectUDP

func ConnectUDP(port string) *net.UDPConn

Creates a UDP Connection to the given port. The port is passed to net.ResolveUDPAddr to start the connection

func ReadUDP

func ReadUDP(conn *net.UDPConn, packetData []byte, extraData []byte)

Reads the data available on the UDP connection Data will be read into packet data and extra data

func StartServer

func StartServer(handlers Handlers, options ...Option)

Starts the WebSocket server with the given handler If a addr option is not specified the default port is 8080
