[PYTHON] Make a LINE BOT (chat)

Make a chat LINE BOT using A3RT

Improve the previously created Make LINE BOT and use the A3RT Talk API provided by Recruit to create a BOT for chatting. Had made.

(1) Get API KEY from A3RT

Issue API KEY on A3RT site.

(2) Check the structure of A3RT

Check the structure of A3RT before modifying main.py created last time. Execute the following code to check the structure of A3RT and check if the AI returns the answer to "Good morning" properly. First, install pya3rt in a virtual environment,

pip install pya3rt

Try running the following in python mode in your terminal.

import pya3rt

apikey = "*******************************"
client = pya3rt.TalkClient(apikey)
reply_message = client.talk("Good morning")

print(reply_message)

{'status': 0,'message': 'ok','results': [{'perplexity': 0.07743213382788067, 'reply': 'Good morning'}]}

Will be. I want to get "Good morning" in the reply, so I modified it as follows

import pya3rt

apikey = "****************************"
client = pya3rt.TalkClient(apikey)
reply_message = client.talk("Good morning")

print(reply_message['results'][0]['reply'])

Then

Good morning

Then, he properly returned "Good morning" → "Good morning". Incorporate this into the previously created main.py.

(3) Modify the previously created main.py

First, the above description of pya3rt is made into a function as follows.

def talk_ai(word):
    apikey = "****************************"
    client = pya3rt.TalkClient(apikey)
    reply_message = client.talk(word)
    return reply_message['results'][0]['reply']

Last time Modify the created main.py.

    app.logger.info("Request body: " + body)

    try:
        handler.handle(body, signature)
    except InvalidSignatureError:
        print("Invalid signature. Please check your channel access token/channel secret.")
        abort(400)
    return 'OK'



@handler.add(MessageEvent, message=TextMessage)
def handle_message(event):
    #(Addition) talk_Pass the argument to the ai method and get the return value ai_Assign to message
    ai_message = talk_ai(event.message.text)
    line_bot_api.reply_message(
        event.reply_token,
        #TextSendMessage(text=event.message.txt))
        #(Fixed) ai_Return message
        TextSendMessage(text=ai_message))

#(Addition) Reply ai conversation with pya3rt
def talk_ai(word):
    apikey = "****************************"
    client = pya3rt.TalkClient(apikey)
    reply_message = client.talk(word)
    return reply_message['results'][0]['reply']

if __name__ == "__main__":
    port = int(os.getenv("PORT", 5000))
    app.run(host="0.0.0.0", port=port)

If you can fix it, update requirements.txt and

pip freeze > requirements.txt

After that, deploy it to Heroku and you're done.
