使用Flask在HEROKU部屬，首先遇到上傳失敗(remote rejected)的問題，不過後來已解決，接著，上傳成功後又遇到應用程式錯誤(application error)的問題，以下詳列我的步驟，想請教問題的所在 :) 。

  1. 建立一個資料夾python-flask2，
    在此資料夾中建立app.py、Procfile、requirements.txt、runtime.txt(但後來發現runtime.txt刪除後才能順利上傳，因此runtime.txt沒有寫!)

  2. python-flask2資料夾中新增app.py，其中程式碼如下:

from flask import Flask #載入Flask
app=Flask(__name__) #建立application 物件

#建立網站首頁的回應方式
@app.route("/") 
def index(): #用來回應網頁首頁連線的函式
    return "hello flask!!!!!吃早餐了"

@app.route("/page1")
def info():
    return "相關資訊"
#啟動伺服器
app.run()
  1. python-flask2資料夾中新增Procfile，內容如下: 
web: gunicorn app:app
  1. python-flask2資料夾中新增requirements.txt，內容如下: 
Flask
gunicorn
  1. Git下載; HEROKU下載CLI、建立APP
  2. 按照HEROKU的部屬指令:
$ heroku login

$ git init
$ heroku git:remote -a python-chiao

$ git add .
$ git commit -am "make it better"
$ git push heroku master

我的終端機執行內容

 * [new branch]      master -> master
  1. 結果
    開啟https://python-chiao.herokuapp.com ，出現Application error。
    檢查logs內容發現每次出現的錯誤代碼都不同，主要是H12、H10、H13，查詢到這些錯誤大致跟啟動超時有關，想請教不曉得針對超時的問題，是否相關經驗的人可提供建議的解決方法?或是根據上述的步驟是否有哪裡出了問題? /images/emoticon/emoticon41.gif
