问题描述

我的应用程序可以使用工头运行在本地正常运行，而当我使用python runserver.py执行我的runserver.py文件时.当我将其推到Heroku时，它崩溃了.我什至更改了我的procfile:web: python runserver.py ${PORT}，以便Heroku可以绑定到端口号，但无济于事...我已经解决了近3天了.首先是我的Procfile，现在是Heroku...任何帮助将不胜感激.另外，我在该项目的Flask框架中使用Python –我遇到了Heroku，但似乎只适用于RoR应用程序.

My app runs fine locally using foreman run, and when I execute my runserver.py file using python runserver.py. When I push it to Heroku, it just crashes. I even made changes to my procfile: web: python runserver.py ${PORT} so that Heroku will bind to a port number, but to no avail...I've been at this problem for almost 3 days now. First with my Procfile and now with Heroku...any help would gladly be appreciated. Additionally, I am using Python with the Flask framework for this project -- I came across Heroku forward, but it seems to be only for RoR applications..

Procfile:

web: python runserver.py ${PORT}

runserver.py:

from intro_to_flask import app

app.run(debug=True)

推荐答案

我找到了此问题的答案...本质上，我必须绑定端口并指定要使用的主机:

I found the answer to this issue...essentially I had to bind a port and specify the host that I am using:

在我的runserver.py文件中，我使用以下命令对其进行了修改:

In my runserver.py file I modified it using:

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)

这可能不是最优雅的方法，但是它可以工作.

It's probably not the most elegant way of doing it.but it works.
