使用 LINE BOT SDK

搭配Flask使用 LINE BOT SDK

LINE BOT SDK Github https://github.com/line/line-bot-sdk-python

1 使用pip安裝 LINE BOT SDK

pip3 install line-bot-sdk

2 參考官網的範例建立一個app.py

#app.py
from flask import Flask, request, abort

from linebot import (
    LineBotApi, WebhookHandler
)
from linebot.exceptions import (
    InvalidSignatureError
)
from linebot.models import (
    MessageEvent, TextMessage, TextSendMessage,
)

app = Flask(__name__)

line_bot_api = LineBotApi('貼上你的line bot channel token')
handler = WebhookHandler('貼上你的line bot channel secret')


@app.route("/callback", methods=['POST'])
def callback():
    # get X-Line-Signature header value
    signature = request.headers['X-Line-Signature']

    # get request body as text
    body = request.get_data(as_text=True)
    app.logger.info("Request body: " + body)

    # handle webhook body
    try:
        handler.handle(body, signature)
    except InvalidSignatureError:
        abort(400)

    return 'OK'


@handler.add(MessageEvent, message=TextMessage)
def handle_message(event):
    line_bot_api.reply_message(
        event.reply_token,
        TextSendMessage(text=event.message.text))


if __name__ == "__main__":
    app.run()

上述程式碼運作流程圖

最後run起來若看到Python成功執行就先算成功囉~ 接下來會教你怎麼測試這支API
