使用Web套接字和Gunicorn運行Flask應用程序時出錯

Question

使用gunicorn在本地服務器上運行我的應用程序時，我收到以下錯誤日志：

[2019-06-10 20:12:20 +0200] [34160] [ERROR] Socket error processing request.
Traceback (most recent call last):
  File "/Users/user/Documents/project/venv/lib/python3.6/site-packages/gunicorn/workers/sync.py", line 135, in handle

    sock.sendall(data)
OSError: [Errno 9] Bad file descriptor

我的gunicorn配置如下，我使用gunicorn執行它-w 4 -b 0.0.0.0:8080 uwsgi：app config = config.ini：

[server:main]
workers = 4
worker_class = 'eventlet'
bind = '0.0.0.0:8080'
reload = False
daemon = True
timeout = 1200
port = 8080

通過Flask-SocketIO進行Web套接字連接的代碼：

app = Flask(__name__)
Session(app)
socketio = SocketIO(app)

我正在使用Flask-SocketIO，現在我只是想在我的本地機器上沒有Nginx的情況下讓套接字框架在wsgi服務器上工作。 有關問題可能是什么的任何建議？ 不能從這些錯誤日志中拼湊出來 - 提前感謝任何建議！

我不得不將worker指定為eventlet，現在它正在使用gunicorn在本地機器上工作。 我這樣做是通過運行：

gunicorn -w 1 -b 0.0.0.0:8080 app：app --worker-class eventlet --reload
