LINE BOT Message 初學者記錄(八) Casual template: Yelp restaurant + Location 為了能在各國旅遊時可以方便找到優質餐廳, 結合 Location 和 Yelp 即可輕鬆達成
先看作品完成圖: 不管德國, 台灣, 美國… 都可輕鬆取得優質餐廳資訊
Step1 - Distinguish message from user is Location or Text:Permalink
從上圖看出使用者輸入 location 會有一個 type: location, 因此我們只需要在 main function 裡判斷來源字串的 message_type 即可
if message_type == 'location':
Step2 - Yelp function:Permalink
我們 github 可看到現成的 yelp api in Python language. 並將吃進去的 address 最後 filter 出我們要的 ‘name’, ‘address’, ‘photo’, ‘url’
