聊天機器人
想說Linebot弄完後順便連Facebookbot一併弄一下好了
bot也算是兩年前的東西了，以前寫沒留下近期內用到再來寫一下作教學文
不然每次的話都要再重找
不過Facebookbot比較麻煩一點就是了
那在我們上一回的Linebot都裝的差不多了，
為什麼技術文章寫來寫去還是很像在寫心情雜記xd

裝完後跑一下code

	import os, sys
	from flask import Flask, request
	from pymessenger import Bot
	app = Flask(__name__)
	PAGE_ACCESS_TOKEN = "XXXXXXXXXXXXXXXXXXXXXXXXXXXX"
	bot = Bot(PAGE_ACCESS_TOKEN)
	@app.route('/', methods=['GET'])
	def verify():
	# Webhook verification
	if request.args.get("hub.mode") == "subscribe" and request.args.get("hub.challenge"):
	if not request.args.get("hub.verify_token") == "hello":
	return "Verification token mismatch", 403
	return request.args["hub.challenge"], 200
	return "Hello world", 200
	@app.route('/', methods=['POST'])
	def webhook():
	data = request.get_json()
	log(data)
	if data['object'] == 'page':
	for entry in data['entry']:
	for messaging_event in entry['messaging']:
	# IDs
	sender_id = messaging_event['sender']['id']
	recipient_id = messaging_event['recipient']['id']
	if messaging_event.get('message'):
	# Extracting text message
	if 'text' in messaging_event['message']:
	messaging_text = messaging_event['message']['text']
	else:
	messaging_text = 'no text'
	# Echo
	response = messaging_text
	bot.send_text_message(sender_id, response)
	return "ok", 200
	def log(message):
	print(message)
	sys.stdout.flush()
	if __name__ == "__main__":
	app.run(debug = True, port = 80)

記得替換掉token
端口與ngork端口需要一至

啟動伺服器

直接開密!

ngork伺服器響應時間有夠慢的，然後既然是免費的嗎算惹

如果在權杖有問題的話這邊可以把webhooks進行移除
