README
# websocket [](https://pkg.go.dev/github.com/xgfone/go-websocket) [](https://raw.githubusercontent.com/xgfone/go-websocket/master/LICENSE)
This is a websocket implementation supporting `Go1.7+`, which is inspired by [websockify](https://github.com/novnc/websockify) and [websocket](https://github.com/gorilla/websocket).
#### Difference from `gorilla/websocket`
- `gorilla/websocket` only 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
```shell
$ go get -u github.com/xgfone/go-websocket
```
## VNC Proxy on WebSocket
The sub-package [vncproxy](https://github.com/xgfone/go-websocket/tree/master/vncproxy) provides a HTTP handler about VNC Proxy on Websocket.
## Example
### Websocket Server Example
```go
package main
import (
"log"
"net/http"
"time"
"github.com/xgfone/go-websocket"
)
var upgrader = websocket.Upgrader{
MaxMsgSize: 1024,
Timeout: time.Second * 30,
CheckOrigin: func(r *http.Request) bool { return true },
}
func websocketHandler(rw http.ResponseWriter, r *http.Request) {
ws, err := upgrader.Upgrade(rw, r, nil)
if err != nil {
log.Printf("failed to upgrade to websocket: %s\n", err)
return
}
ws.Run(func(msgType int, message []byte) {
switch msgType {
case websocket.MsgTypeBinary:
ws.SendBinaryMsg(message)
case websocket.MsgTypeText:
ws.SendTextMsg(message)
}
})
}
func main() {
http.ListenAndServe(":80", http.HandlerFunc(websocketHandler))
}
```
### Websocket Client Example
```go
package main
import (
"fmt"
"time"
"github.com/xgfone/go-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:
