Heroku App立即崩溃,出现R10和H10错误

Question

我的应用程序使用foreman run在本地运行正常,当我runserver.py使用执行我的文件时python runserver.py.当我把它推到Heroku时,它只是崩溃了.我甚至对我的procfile进行了更改:web: python runserver.py ${PORT}这样Heroku将绑定到一个端口号,但无济于事......我已经在这个问题上待了将近3天了.首先是我Procfile和现在的Heroku ...任何帮助都会很高兴得到赞赏.另外,我在这个项目中使用带有Flask框架的Python - 我遇到了Heroku前进,但它似乎只适用于RoR应用程序..

Procfile:

web: python runserver.py ${PORT}

runserver.py:

from intro_to_flask import app

app.run(debug=True)

Answer 1

我找到了这个问题的答案......基本上我必须绑定一个端口并指定我正在使用的主机:

在我的runserver.py文件中,我使用以下方法修改它:

import os
from intro_to_flask import app

port = int(os.environ.get("PORT", 5000))
app.run(debug=True, host='0.0.0.0', port=port)

它可能不是最优雅的方式.但它确实有效.
