第一步:將昨天下載完的壓縮檔解壓縮，取出line-bot-sdk-python-master\examples中的flask-echo資料夾將其中資料和Linebot資料夾轉移至我們創立的資料夾


第二步:編輯app.py

更改紅框內的內容將其改成在LINE提供的channel_secret和channel_access_token(可於LINE Developer尋找),於def callback副程式內加上print(body)
將flask,future,requests, line_bot_sdk,gunicorn, psycopg這些字串放入requirements.txt檔裡面讓Heroku記得下載

第三步:回到CMD

1. 輸入heroku login
   
   按下Log in後關閉
2. 輸入heroku git:remote -a {Heroku專案名}
3. 輸入git init
4. 輸入git add .
5. 輸入git commit -am'ok'
6. 最後輸入git push heroku master
