webex-bot 0.2.5

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

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"))

# 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 webex_bot.cards.echo_card import ECHO_CARD_CONTENT
from webex_bot.formatting import quote_info
from webex_bot.models.command import Command

log = logging.getLogger(__name__)


class EchoCommand(Command):

    def __init__(self):
        super().__init__(
            command_keyword="echo",
            help_message="Type in something here and it will be echo'd back to you. How useful is that!",
            card=ECHO_CARD_CONTENT)

    def execute(self, message, attachment_actions):
        """
        If you want to respond to a submit operation on the card, you
        would write code here!

        You can return text string here or even another card (Response).

        This sample command function simply echos back the sent message.

        :param message: message with command already stripped
        :param attachment_actions: attachment_actions object
        :return: a string or Response object. Use Response if you want to return another card.
        """
        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!
