WebsocketMessage 中 getPayload()的方法是什么意思

//接受消息,并发送出去
@Override
public void handleMessage(WebSocketSession session,
WebSocketMessage<?> message) throws Exception {

    Map<String, Object> attributes = session.getAttributes();
   /*  WUserToken user = (WUserToken) attributes.get(SessionManager.USER_SESSION);
    WMachineList machine = (WMachineList) attributes.get(SessionManager.MACHINE_SESSION);
    sessionManager.sendMessage(machine.getNumber() ,user, message.getPayload()+"");
    */
    MessageInfo messageInfo = (MessageInfo) attributes.get("message_info");
    WMachineList machine = (WMachineList) attributes.get("w_machine_list");
    sessionManager.sendMessage(machine.getNumber(),messageInfo.getUserId(),message.getPayload()+"");

}
    中 message.getPayload()表示什么意思
