Python + Slack Bot – 3

さてリアルタイムでとりあえずうまくいったので、もう少し違うサンプルコードを試してみる。

参考にしたのはこちら。

https://www.fullstackpython.com/blog/build-first-slack-bot-python.html

ただしこのコードが書かれた当時とSlackのレスポンスが変わっているようなのでそのままでは動かない。

下記は変更後。これによりdoを入力すると別のレスポンスが返ってくるようになった。

import os
import time
import re
from slackclient import SlackClient
# instantiate Slack client
slack_client = SlackClient("xoxp-")
# starterbot's user ID in Slack: value is assigned after the bot starts up
starterbot_id = None

# constants
RTM_READ_DELAY = 1 # 1 second delay between reading from RTM
EXAMPLE_COMMAND = "do"
MENTION_REGEX = "^<@(|[WU].+?)>(.*)"

def parse_bot_commands(slack_events):

  print(slack_events)
  for event in slack_events:
    if event["type"] == "message" and not "subtype" in event:
      message = event["text"]
      user_id = event["user"]
      print(user_id + ":" + starterbot_id)
    if user_id == starterbot_id:
      return message, event["channel"]
  return None, None

def handle_command(command, channel):

  # Default response is help text for the user
  default_response = "Not sure what you mean. Try *{}*.".format(EXAMPLE_COMMAND)

  # Finds and executes the given command, filling in response
  response = None

  # This is where you start to implement more commands!
  if command.startswith(EXAMPLE_COMMAND):
    response = "Sure...write some more code then I can do that!"

  # Sends the response back to the channel
  slack_client.api_call(
    "chat.postMessage",
    channel=channel,
    text=response or default_response
  )

if __name__ == "__main__":
  if slack_client.rtm_connect(with_team_state=False):
    print("Starter Bot connected and running!")
    # Read bot's user ID by calling Web API method `auth.test`
    starterbot_id = slack_client.api_call("auth.test")["user_id"]
    while True:
      command, channel = parse_bot_commands(slack_client.rtm_read())
      if command:
        handle_command(command, channel)
      time.sleep(RTM_READ_DELAY)
  else:
    print("Connection failed. Exception traceback printed above.")
