an active HTTP request. Consult the documentation on testing for
information about how to avoid this problem.

我需要将代码放在 gunicorn 上以便在线程上提供它。知道为什么它不起作用吗？
它不起作用，因为 index 不是 wsgi app - 函数具有正确的签名是不够的。请改为执行以下操作：
gunicorn -w 4 myapp:app -b 10.91.1.230:5055 &
当您 运行 python3 myapp.py 时您看不到任何问题，因为 flask 的开发服务器 app.run 不需要 wsgi 应用程序，而 gunicorn 需要。话虽如此，您不妨继续并删除 index 签名。
