heroku无法使用我的python脚本

时间：2015-02-06 06:51:15

标签： python heroku flask

我是python和flask的新手。 该烧瓶的文档说您可以将您的应用程序部署到heroku以供公众访问。所以我转向了heroku网站。我一步一步地跟着入门指南。我成功部署了应用程序，但是当我使用https://mighty-falls-2223.heroku.com/之类的给定网址进行测试时，它表示存在错误。

错误消息是：

An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

我试过heroku logs命令：

Procfile：

web:gunicorn app:app

（我已遵循dirn的建议将Procfile内容更改为web：gunicorn index：app，但错误仍在此处。）

requirements.txt：

Flask>=0.9
Jinja2>=2.7.2
Werkzeug>=0.9.4
gunicorn>=18.0

由于我是这些东西的新手，所以我只是复制并粘贴其他人的Procfile和requirements.txt。

所有文件都在一个目录中。

在本地环境中，我只需要打开终端，然后运行命令：python~ / index.py，终端显示：

* Running on http://0.0.0.0:5000/
* Restarting with reloader

然后一切都按原样运作。从客户端应用程序，我可以使用一些json数据发布到url：http://0.0.0.0:5000/test，客户端应用程序将收到相同的json数据。

我不知道如何修复它。我只想在服务器中运行此脚本，脚本可以响应来自Internet的客户端应用程序请求。

问题在于您的Procfile。 

web:gunicorn app:app

这告诉gunicorn运行名为app的WSGI应用程序，该应用程序可以在名为app的模块或包中找到。但是，您的模块名为index。

您可以将index.py重命名为app.py或将Procfile的内容更改为

web:gunicorn index:app
