Question

使用gunicorn在本地服务器上运行我的应用程序时，出现以下错误日志：

[2019-06-10 20:12:20 +0200] [34160] [ERROR] Socket error processing request.
Traceback (most recent call last):

OSError: [Errno 9] Bad file descriptor

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

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

通过Flask-SocketIO进行Web套接字连接的代码：

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

我正在使用Flask-SocketIO，现在我只是想让套接字框架在wsgi服务器上工作而本地计算机上没有Nginx。关于问题可能有什么建议？无法从这些错误日志中将其拼凑在一起-预先感谢您提供任何建议！

我必须将worker指定为eventlet，现在它正在使用gunicorn在本地计算机上工作。我通过运行来做到这一点：

gunicorn -w 1 -b 0.0.0.0:8080 app：app --worker-class事件 -重新加载

使用Web套接字和Gunicorn运行Flask应用程序时出错
