Question

我试图在现有的烧瓶缓冲应用程序中支持websocket，将gunicorn超时设置为20秒。我决定使用flask-socket扩展，但事情进展顺利，但是在20秒后，greentlet会超时。

我假设websocket连接被视为普通的http请求，因此它应该返回一个使用greenlet超时的响应。

我添加了以下代码，并将gunicorn worker_class更改为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")

我该如何处理这种情况？谢谢你的任何建议。

添加输出：

Timeout: 20 seconds

发现超时是由我们使用的框架设置的。它为烧瓶app添加了一个中间件来为每个api调用设置超时。更改超时配置可以解决这个问题。
