【问题描述】:
我开始遇到与this question 相同的问题。正如其中一个答案所暗示的那样,可以通过使应用程序在没有 SSL 的情况下运行来避免该特定问题。但由于 Facebook 将在短短几天内(2011 年 10 月 1 日)为应用程序强制实施 https,这似乎是一个不会持久的解决方案。我首先尝试在 app.run 中启用 ssl(在exampleapp.py 的第 149 行附近。像这样:
app.run(host='0.0.0.0', port=port, ssl_context='adhoc')
第一次尝试失败,开始抱怨缺少 OpenSSL 模块。在网上找到了一些关于如何解决这个问题的建议,然后选择这样做:
(myapp)$ pip install pyopenssl
现在开始时没有投诉:
(myapp)$ foreman start

10:35:26 web.1 | * Running on https://0.0.0.0:5000/
10:35:26 web.1 | * Restarting with reloader
但是当尝试访问应用程序时:
10:35:31 web.1 | ----------------------------------------

怎么办?是错误的 Python 版本还是只是我误解了其他一些基本的东西?
