Keep a bot on Skype

It's terribly new, but I decided to invite the bot to Skype. It is a work memo at that time.

However, the reaction of the bot may be dull.

EC2 configuration

The bot hut is EC2 (CentOS6).

item	value
region	ap-northeast-1
AMI	CentOS 6 (ami-25436924)

Installation

The following is a list of commands assuming that you are logged in with root privileges.

Advance preparation

Yum install what you need in advance.

ec2# yum install -y http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
ec2# yum install -y qtwebkit.i686 webkitgtk.i686 alsa-lib.i686 libXv.i686 libXScrnSaver.i686 gtk2-engines.i686 PackageKit-gtk-module.i686 libcanberra.i686 libcanberra-gtk2.i686 pulseaudio-libs.i686 alsa-plugins-pulseaudio.i686
ec2# yum install -y x11vnc ipa-gothic-fonts xauth Xvfb dbus-x11 wget

Install Skype

Installation

Creating a startup script

Create a startup script like the one below.

Enter USERNAME / PASSWORD
Users can be created from https://login.skype.com/intl/ja/account/signup-form

Grant execute permission.

ec2# chmod +x /etc/init.d/skype

Launch Skype

ec2# /etc/init.d/skype start

Access with VNC

iptables settings

Let's free port 5900 for VNC.

If you are not sure, copy the line of port 22 and add the line of port 5900.

ec2# vi /etc/sysconfig/iptables
ec2# service iptables restart

Start VNC

ec2# x11vnc -display :20

Access the started VNC with VNC Viewer

Download and install the client software from TigerVNC Project Japanese Top Page - SourceForge.JP.

You can check the global IP address of the EC2 instance you are currently logged in to with the following command.

ec2# curl http://169.254.169.254/latest/meta-data/public-ipv4;echo

Launch TigerVNC Viewer and connect to (EC2 IP address): 5900

Once connected, select a language and click "Agree"

The sign-in screen will appear, but if you leave it as it is With USERNAME / PASSWORD described in the startup script, Log in without permission.

When the screen after login appears, leave VNC Viewer for a while Return to work on the server side.

Conversation with the bot

Install Skype4Py

ec2# wget https://pypi.python.org/packages/source/d/distribute/distribute-0.6.49.tar.gz
ec2# tar xpvf distribute-0.6.49.tar.gz
ec2# python distribute-0.6.49/setup.py install
ec2# easy_install Skype4Py

Write a bot script

As a sample When you call it a "bot" Write a script that returns "| ΦωΦ) ...".

`bot.py`


# encoding: utf-8

import Skype4Py
import time

def handler(msg, event):
    if event == u"RECEIVED":
        if msg.Body == u"Bot":
            msg.Chat.SendMessage(u"|ΦωΦ) ...")

def main():
    skype = Skype4Py.Skype(Transport='x11')
    skype.OnMessageStatus = handler
    skype.Attach()
    while True:
        time.sleep(1) 

if __name__ == "__main__":
    main()

Launch the bot

ec2# export DISPLAY=:20;
ec2# python bot.py

On the VNC Viewer side that was left as it is, The following message will be displayed, so Check "Remember this selection" and click "Yes".

Try talking to your bot from another skype

Well done ☆

Clean up

Let's shut down the VNC server. (Skype is still running, so there is no problem)

Raise bots

Let's install various reactions on the bot.

# encoding: utf-8

import Skype4Py
import time
import re #← Add

def handler(msg, event):

    if event == u"RECEIVED":

        #----Perfect matching
        if msg.Body == u"I am":
            msg.Chat.SendMessage(u"In you")
            return

        #----Search
        if re.search(u"you", msg.Body, re.S):
            msg.Chat.SendMessage(u"With me")

        #----Multiple lines
        if re.search(u"Get up", msg.Body, re.S):
            gataMsg = u"""Oh!!

"""
            msg.Chat.SendMessage(gataMsg)

        #----List extraction
        if re.search(u'I', msg.Body, re.S):
            list = re.findall(u'I', msg.Body, re.S)
            cnt = len(list)
            msg.Chat.SendMessage(u"[Self-consciousness warning] I: "+str(cnt))

        #----String replacement
        # note: python 2.6 series re.flags cannot be used in sub...
        #       http://docs.python.jp/2/library/re.html#re.sub
        if re.search(u'I', msg.Body):
            lines = msg.Body.splitlines()
            msg.Chat.SendMessage(u'understood.')
            for line in lines :
                you = re.sub(u'you', u'-you-', line)
                you = re.sub(u'I', u'you', you)
                you = re.sub(u'-you-', u'I', you)
                msg.Chat.SendMessage(you)
            msg.Chat.SendMessage(u'That's right.')

def main():
    skype = Skype4Py.Skype(Transport='x11')
    skype.OnMessageStatus = handler
    skype.Attach()
    while True:
        time.sleep(1) 

if __name__ == "__main__":
    main()

Invite bots to groups

There are "cloud-based" and "P2P-based" things in Skype chat The recently created group seems to be a "cloud-based" chat.

"What are the chat commands and roles? --Skype Support FAQ " https://support.skype.com/ja/faq/FA10042/

···so, Is it a SkypeApi specification, a Skype4Py specification, or a problem with my writing style? For "cloud-based" groups, bots didn't recognize the group well.

Therefore, “Invite bots to groups” If you want to “bots notify the group of messages” I will use "P2P base".

The currently open group To check if it is "cloud-based" or "P2P-based" From the message input field, throw the following command.

/get name

From the explanation on the above Skype-FAQ page, it seems that it can be determined as follows.

If the group name response starts with "19: ...", then you are using cloud-based chat. If the group name response starts with "#skypename ...", you are using P2P-based chat.

To create a "P2P-based" group, From the message input field (any chat is OK), throw the following command.

/createmoderatedchat

If possible, it is desirable for the bot itself to throw this command. (Because the resident bot can become an administrator)

It's also a hassle to do from VNC Viewer, so log in to your bot account on your PC I think it's better to work there.

Let's add members to the newly created "P2P-based" group.

Notify a message

It ’s not just a passive reaction, I would like to be actively notified by bots.

To users

Please change the user name of the notification destination as appropriate. By registering the following command in the scheduler etc. At any time (on time, event occurrence, etc.) It is possible to notify the message, It can be used as a reminder or alert notification.

It may be necessary for the bot and the user to register the contact list in advance (unconfirmed).

Notification script

`send_message_for_user.py`


# -*- coding: utf-8 -*-
import Skype4Py
import sys

user = 'username' #Rewrite required

argvs = sys.argv
acnt = len(argvs)

skype = Skype4Py.Skype(Transport='x11')
skype.Attach()

msg = argvs[1] if acnt > 1 and argvs[1] else 'energy?'

chat = skype.CreateChatWith(user)
chat.SendMessage(msg)

Notification command

ec2# export DISPLAY=:20;
ec2# python send_message_for_group.py 'Animation will start in 30 minutes'

To the group

Notifications to groups are a little special Find the target group from the list of chats you belong to I am trying to notify the message only when it is the corresponding group.

Notification script

`send_message_for_group.py`


# -*- coding: utf-8 -*-
import Skype4Py
import sys

argvs = sys.argv
acnt = len(argvs)

skype = Skype4Py.Skype(Transport='x11')
skype.Attach()

msg = argvs[1] if acnt > 1 and argvs[1] else 'energy?'

for chat in skype.Chats :
    if chat.Name == '#skype_group_name/$1234567890abcdef': #Rewrite required
        chat.SendMessage(msg)

Notification command

ec2# export DISPLAY=:20;
ec2# python send_message_for_group.py 'It's lunch time, everyone.'

Finally

When using it for business, please be careful about security.
