Functions

func AuthPreChecker

func AuthPreChecker(i AfterAuthenticated) func(w http.ResponseWriter, r *http.Request)

func DispatchMessage

func DispatchMessage(sshSession *ssh.Session, messageType websocket.MessageType, wsData []byte, wc io.WriteCloser) error

func SignIn

Types

type AfterAuthenticated

type AfterAuthenticated interface {
	// make sure token and session is not nil.
	ServeAfterAuthenticated(w http.ResponseWriter, r *http.Request, token *utils.Claims, session utils.Session)
	ShouldClearSessionAfterExec() bool
}

type SSHWebSocketHandle

type SSHWebSocketHandle struct {
	// contains filtered or unexported fields
}

func NewSSHWSHandle

func NewSSHWSHandle(bfc int) *SSHWebSocketHandle

func (*SSHWebSocketHandle) SSHShellOverWS

func (c *SSHWebSocketHandle) SSHShellOverWS(ctx context.Context, ws *websocket.Conn, host string, port int, username string, auth ssh.AuthMethod, cols, rows uint32) error

ssh shell over websocket first,we establish a ssh connection to ssh server when a webSocket comes; then we deliver ssh data via ssh connection between browser and ssh server. That is, read webSocket data from browser (e.g. 'ls' command) and send data to ssh server via ssh connection; the other hand, read returned ssh data from ssh server and write back to browser via webSocket API.

func (*SSHWebSocketHandle) ServeAfterAuthenticated

func (c *SSHWebSocketHandle) ServeAfterAuthenticated(w http.ResponseWriter, r *http.Request, claims *utils.Claims, session utils.Session)

handle webSocket connection.

func (*SSHWebSocketHandle) ShouldClearSessionAfterExec

func (c *SSHWebSocketHandle) ShouldClearSessionAfterExec() bool

clear session after ssh closed.

type WebSocketBufferWriter

type WebSocketBufferWriter struct {
	// contains filtered or unexported fields
}

write data to WebSocket the data comes from ssh server.

func (*WebSocketBufferWriter) Flush

func (w *WebSocketBufferWriter) Flush(ctx context.Context, messageType websocket.MessageType, ws *websocket.Conn) error

flush all data in this buff into WebSocket.

func (*WebSocketBufferWriter) Write

func (w *WebSocketBufferWriter) Write(p []byte) (int, error)

implement Write interface to write bytes from ssh server into bytes.Buffer.
