Simple Golang server socket long connection skeleton
## Useage
```go
go get github.com/yale8848/gosocket
```
- server
```go
package main
import (
"fmt"
"github.com/yale8848/gosocket"
)

}
func (s *ServerHandlerImp) Connect(session *gosocket.Session) {
fmt.Println("Connect : ")
}

fmt.Println("ReadData : IsHeartBeat")

} else {
fmt.Println("ReadData :" + protocol.String())
d := protocol.Encode(protocol.GetData())
session.WriteData(d)
}
}
func (s *ServerHandlerImp) Close(session *gosocket.Session) {
fmt.Println("Close : ")
}
func (s *ServerHandlerImp) AcceptError(err error) {
fmt.Println("AcceptError : " + err.Error())
}
func (s *ServerHandlerImp) ReadTimeout(err error) {
fmt.Println("ReadTimeout : " + err.Error())
}

server.Start(&gosocket.Config{
Network: "tcp", Address: ":7777", NetworkListen: "tcp", ReadTimeout: 20})
}
```
- client
