我使用 flask 服务器从服务器提供静态文件，但有时服务器变得完全无响应，下载文件一直在加载但从未下载。当我打开终端时，我发现了一些奇怪的请求，我按下 CTRL + C，服务器立即再次响应并继续下载。这种情况经常发生，我不知道是什么原因造成的，也不知道如何防止它卡住我的 flask 服务器，这是有人试图破解吗？

最佳答案
我遇到了同样的问题。在 django/flask 应用程序中，当以 python server.py 运行时挂起是很常见的，因为这不是它们的最佳环境。仅将其用于测试目的。当你用完它并想发布时，你应该把它放在 wsgi/uwsgi + apache/nginx 后面，你的问题就会消失。
