Types

type ISession

type ISession interface {
	Execute(log.T) error
	OpenDataChannel(log.T) error
	ProcessFirstMessage(log log.T, outputMessage message.ClientMessage) (isHandlerReady bool, err error)
	Stop()
	GetResumeSessionParams(log.T) (string, error)
	ResumeSessionHandler(log.T) error
	TerminateSession(log.T) error
}

type ISessionPlugin

type ISessionPlugin interface {
	SetSessionHandlers(log.T) error
	ProcessStreamMessagePayload(log log.T, streamDataMessage message.ClientMessage) (isHandlerReady bool, err error)
	Initialize(log log.T, sessionVar *Session)
	Stop()
	Name() string
}

type Session

type Session struct {
	DataChannel           datachannel.IDataChannel
	SessionId             string
	StreamUrl             string
	TokenValue            string
	IsAwsCliUpgradeNeeded bool
	Endpoint              string
	ClientId              string
	TargetId              string

	SessionType       string
	SessionProperties interface{}
	DisplayMode       sessionutil.DisplayMode
	// contains filtered or unexported fields
}

func (*Session) Execute

func (s *Session) Execute(log log.T) (err error)

Execute create data channel and start the session

func (*Session) GetResumeSessionParams

func (s *Session) GetResumeSessionParams(log log.T) (string, error)

GetResumeSessionParams calls ResumeSession API and gets tokenvalue for reconnecting

func (*Session) OpenDataChannel

func (s *Session) OpenDataChannel(log log.T) (err error)

OpenDataChannel initializes datachannel

func (*Session) ProcessFirstMessage

func (s *Session) ProcessFirstMessage(log log.T, outputMessage message.ClientMessage) (isHandlerReady bool, err error)

ProcessFirstMessage only processes messages with PayloadType Output to determine the sessionType of the session to be launched. This is a fallback for agent versions that do not support handshake, they immediately start sending shell output.

func (*Session) ResumeSessionHandler

func (s *Session) ResumeSessionHandler(log log.T) (err error)

ResumeSessionHandler gets token value and tries to Reconnect to datachannel

func (*Session) Stop

func (s *Session) Stop()

Stop will end the session

func (*Session) TerminateSession

func (s *Session) TerminateSession(log log.T) error

TerminateSession calls TerminateSession API
