使用燒瓶插座時的工作者超時

Question

我試圖在現有的燒瓶平靜應用中將websocket設置爲20秒。我決定使用瓶子插槽擴展，除了20秒後greentlet會超時之外，事情進展順利。

我假設websocket連接被視爲一個普通的http請求，所以它期望返回一個響應util greenlet超時。

添加以下代碼，改變了gunicorn worker_class到geventwebsocket.gunicorn.workers.GeventWebSocketWorker

sockets = Sockets(app) 
@sockets.route('/log') 
def test_connect(socket): 
    while not socket.closed: 
     import time 
     time.sleep(2) 
     socket.send("heart beating") 

我應該如何處理這種情況？感謝您的任何建議。

研究發現，超時被我們使用的框架集。它向flask應用程序添加一箇中間件來爲每個api調用設置超時。改變超時配置可以解決這個問題。
