前置作業

上面會用到的兩個網址

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

下載後呢

ngrok http 5000

view raw ngrok hosted with ❤ by GitHub

解壓縮完我們執行他

這是將本機端口連到外網
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

	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)
