问题描述
我正在使用gunicorn服务器和gevent工人类的Flask应用程序,它根据是一个异步工作者。然而,当我用一个工作人员启动gunicorn并尝试做一个长时间的请求(我在路由功能中加入了 sleep(10)
),但实际上这也发生在处理大量上传),直到前一个完成后才能发出请求。它的行为就像它是一个同步工作者,一次一个请求。
这是正常行为吗?我错过了关于同步和异步工作者的一些事情吗?
(或使用 gevent
的的非阻塞版本),那么阻止的工作者将阻止整个事件循环。 > 请拨打(或者更具体的)或将您的呼叫替换为 time.sleep

I am using a Flask app with the gunicorn server and the gevent worker class, which according to the gunicorn documentation is an asynchronous worker. However, when I launch gunicorn with a single worker and try to make a long request (I added sleep(10)
in the route function, but in reality this also happens when processing large uploads), I can't make any request until the previous one is finished. It behaves as is it is a synchronous worker, one request at a time.
Is this the normal behavior? Am I missing something about synchronous vs asynchronous workers?
If you don't monkey-patch sleep
(or use gevent
's non-blocking version of sleep
) then a worker that blocks blocks the entire event loop.
Either call gevent.monkey.patch_all
(or more specifically gevent.monkey.patch_time
) or replace your call to time.sleep
with gevent.sleep
