Question

每当我以python3 myapp.py的形式运行我的代码时，它工作得很好，但是每当我使用gunicorn -w 4 myapp:index -b 10.91.1.230:5055 &

它抛出

This typically means that you attempted to use functionality that needed
an active HTTP request.  Consult the documentation on testing for
information about how to avoid this problem.

在我的app.py在

我需要把代码放在gunicorn上，以便在线程上使用它。你知道为什么不能用吗？在

它不起作用，因为index不是wsgi app-这不足以使函数具有正确的签名。请执行以下操作：

gunicorn -w 4 myapp:app -b 10.91.1.230:5055 &

当您运行python3 myapp.py时，您不会发现任何问题，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，您不妨继续删除index签名。在
