webex-bot-ecoen66 0.4.2a0

Python package for a Webex Bot based on websockets.

Introduction

By using this module, you can create a Webex Teams messaging bot quickly in just a couple of lines of code.

This module does not require you to set up an ngrok tunnel to receive incoming messages when behind a firewall or inside a LAN. This package instead uses a websocket to receive messages from the Webex cloud.

Features

• Uses the websockets module to receive incoming messages, thus avoiding the need to have a public IP or use incoming webhooks.
• Simply add 'commands' which are just strings which instruct the bot to perform some action and reply with some result.
• Allows for single or multi-post responses. This is useful if you want to reply with a lot of data, but it won't all fit in a single response.
• Restrict bot to certain users or domains.
• Uses the webexteamssdk package to send back replies from the bot.

🚀 Getting started

---

✨ Sample Project

You can find a sample project, using OpenAI/ChatGPT with this library here: https://github.com/fbradyirl/openai_bot

---

Only Python 3.9 is tested at this time.

1. Install this module from pypi:

pip install webex_bot

2. On the Webex Developer portal, create a new bot token and expose it as an environment variable.

export WEBEX_TEAMS_ACCESS_TOKEN=<your bots token>

3. Run your script:

python example.py

See example.py for details:

import os

from webex_bot.commands.echo import EchoCommand
from webex_bot.webex_bot import WebexBot

# Create a Bot Object
bot = WebexBot(teams_bot_token=os.getenv("WEBEX_TEAMS_ACCESS_TOKEN"),
               approved_rooms=['06586d8d-6aad-4201-9a69-0bf9eeb5766e'],
               bot_name="My Teams Ops Bot",
               include_demo_commands=True)

# Add new commands for the bot to listen out for.
bot.add_command(EchoCommand())

# Call `run` for the bot to wait for incoming messages.
bot.run()

where EchoCommand is defined as:

import logging

from webexteamssdk.models.cards import Colors, TextBlock, FontWeight, FontSize, Column, AdaptiveCard, ColumnSet, \
    Text, Image, HorizontalAlignment
from webexteamssdk.models.cards.actions import Submit

from webex_bot.models.command import Command
from webex_bot.models.response import response_from_adaptive_card

log = logging.getLogger(__name__)


class EchoCommand(Command):

    def __init__(self):
        super().__init__(
            command_keyword="echo",
            help_message="Echo Words Back to You!",
            chained_commands=[EchoCallback()])

    def pre_execute(self, message, attachment_actions, activity):
        """
        (optional function).
        Reply before running the execute function.

        Useful to indicate the bot is handling it if it is a long running task.

        :return: a string or Response object (or a list of either). Use Response if you want to return another card.
        """

        image = Image(url="https://i.postimg.cc/2jMv5kqt/AS89975.jpg")
        text1 = TextBlock("Working on it....", weight=FontWeight.BOLDER, wrap=True, size=FontSize.DEFAULT,
                          horizontalAlignment=HorizontalAlignment.CENTER, color=Colors.DARK)
        text2 = TextBlock("I am busy working on your request. Please continue to look busy while I do your work.",
                          wrap=True, color=Colors.DARK)
        card = AdaptiveCard(
            body=[ColumnSet(columns=[Column(items=[image], width=2)]),

        return response_from_adaptive_card(card)

    def execute(self, message, attachment_actions, activity):

        If you want to respond to a submit operation on the card, you

        """

        text1 = TextBlock("Echo", weight=FontWeight.BOLDER, size=FontSize.MEDIUM)
        text2 = TextBlock("Type in something here and it will be echo'd back to you. How useful is that!",
                          wrap=True, isSubtle=True)
        input_text = Text(id="message_typed", placeholder="Type something here", maxLength=30)
        input_column = Column(items=[input_text], width=2)

        submit = Submit(title="Submit",
                        data={
                            "callback_keyword": "echo_callback"})

        card = AdaptiveCard(
            body=[ColumnSet(columns=[Column(items=[text1, text2], width=2)]),
                  ColumnSet(columns=[input_column]),
                  ], actions=[submit])

        return response_from_adaptive_card(card)


class EchoCallback(Command):

    def __init__(self):
        super().__init__(
            card_callback_keyword="echo_callback",
            delete_previous_message=True)

    def execute(self, message, attachment_actions, activity):
        return quote_info(attachment_actions.inputs.get("message_typed"))

4. Now, just interact 1-1 with the bot. Send it a message with the text:

echo

and off you go!
