python - Python Flask 应用程序不会提供任何 API 请求

Question

我有一个 Flask 应用程序，我试图通过这个应用程序公开几个 API。我正在使用 Docker 启动此应用程序，以下是启动应用程序后的日志：

Joes-MacBook-Pro-78:my-flask-api joe$ docker run -p 5000:5000 --name my-flask-api my-flask-api
/usr/local/lib/python2.7/site-packages/flask_sqlalchemy/__init__.py:819: UserWarning: SQLALCHEMY_DATABASE_URI not set. Defaulting to "sqlite:///:memory:".

我能做些什么来看看这有什么问题吗？我如何调试它以查看更多日志，让我知道后台发生了什么？有任何想法吗？

现在，当我点击 API 时，我在 Chrome 中收到以下错误：

This page isn’t working localhost didn’t send any data.
ERR_EMPTY_RESPONSE
