websocket 
This is a websocket implementation, which is inspired by websockify and websocket.
Difference from gorilla/websocket
gorilla/websocketonly has a goroutine to read from websocket and a goroutine to write to websocket, that's, read or write can be done concurrently.- Though this library cannot read from websocket concurrently, it's able to write to websocket concurrently. Moreover, it will be enhanced to read concurrently.
Install
$ go get -u github.com/xgfone/websocketVNC Proxy on WebSocket
The sub-package vncproxy supplies a HTTP handler about VNC Proxy on Websocket.
Example
Websocket Server Example
package main
import (
"net/http"
"time"
"github.com/xgfone/ship/v2"
"github.com/xgfone/websocket"
)
func main() {
upgrader := websocket.Upgrader{
MaxMsgSize: 1024,
Timeout: time.Second * 30,
CheckOrigin: func(r *http.Request) bool { return true },
}
app := ship.New()
app.R("/").GET(func(ctx *ship.Context) error {
ws, err := upgrader.Upgrade(ctx.Response(), ctx.Request(), nil)
if err != nil {
return err
}
return ws.Run(func(msgType int, message []byte) {
switch msgType {
case websocket.MsgTypeBinary:
ws.SendBinaryMsg(message)
case websocket.MsgTypeText:
ws.SendTextMsg(message)
}
})
})
app.Start(":80").Wait()
}Websocket Client Example
package main
import (
"fmt"
"time"
"github.com/xgfone/websocket"
)
func main() {
ws, err := websocket.NewClientWebsocket("ws://127.0.0.1/")
if err == nil {
go func() {
tick := time.NewTicker(time.Second * 10)
defer tick.Stop()
for {
select {
case now := <-tick.C:
if err := ws.SendTextMsg([]byte(now.String())); err != nil {
fmt.Println(err)
return
}
}
}
}()
err = ws.Run(func(msgType int, msg []byte) {
fmt.Printf("Receive: %s\n", string(msg))
})
}
fmt.Println(err)
}The client will output like this:
