https://developers.line.me/console/channel 上面會用到的兩個網址 https://yaoandy107.github.io/line-bot-tutorial/ 照這位大大把推廣的帳號和line console後台做綁定好了之後呢我們來看一下正題我們先來下載 https://ngrok.com/ 下載後呢

code

ngrok http 5000

解壓縮完我們執行他

執行NGORK

---

LINE Webhook設定

---

這是將本機連接埠連到外網

大家比較有問題的是webhooks

記得把上面設成enable url則跟ngork產生的臨時網址+自己的伺服器回應網址做結合

得到

https://05bfab1a.ngrok.io/callback

那接下來執行

code

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('token')

handler = WebhookHandler('script')

@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)
    print("Request body: " + body, "Signature: " + signature)

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

    return 'OK'


@handler.add(MessageEvent, message=TextMessage)
def handle_message(event):
    #print("Handle: reply_token: " + event.reply_token + ", message: " + event.message.text)
    content = "{}: {}".format(event.source.user_id, event.message.text)
    print (content)
    print('--------------------------------')
    line_bot_api.reply_message(
        event.reply_token,
        TextSendMessage(text=content))

import os

if __name__ == "__main__":
    app.run(debug=True,port=5000)
