Flask：服務器在一段時間后變得沒有響應

Question

我使用燒瓶服務器從服務器提供靜態文件，但偶爾服務器完全沒有響應，下載文件會繼續加載但從不下載。 當我打開終端時，我發現了一些奇怪的請求，我點擊了CTRL + C，服務器立即再次響應並繼續下載。 這種情況經常發生，我不知道是什么導致這種情況以及如何防止它凍結我的燒瓶服務器，這是否有人試圖破解？

我遇到過同樣的問題。 django / flask應用程序在以python server.py運行時掛起是很常見的，因為這不適合它們。 僅用於測試目的。 當你完成它並想要發布時，你應該把它放在wsgi / uwsgi + apache / nginx后面，你的問題就會消失。
