新增Line的webhook
螢光線的地方是在heroku的專案名稱

要新增這些key跟value

開啟Terminal
把資料夾選到你的專案資料夾
然後登入heroku

git config --global user.name "你的名字"
git config --global user.email 你的信箱

git init 第一次才要輸入 之後不用

heroku git:remote -a {HEROKU_APP_NAME} 沒有大括號

git add .
git commit -m "Add code"
git push -f heroku master
上面的依序輸入

TemplateSendMessage
->ButtonsTemplate 按鈕介面
->ConfirmTemplate 確認介面
->CarouseTemplate (多個ButtonsTemplate)
訊息物件中 Image Template message提供互動式介面，會產稱一個Action，Action可以分為以下4種
1. Postback ->按下後透過action=buy&item=111傳送到後台，後台就知道user點了甚麼
2. Message ->幫使用者送出一個訊息
3. URL ->網站
4. Datetime ->告知後台user選擇的使用細節

打開terminal
cd 到你的資料夾
打 python manage.py runserver

再打開一個terminal
cd 到你的資料夾
打 ngrok http 8000(這是端口可以改)
