在Flask Socket.io中禁用记录器 [英] Disabling logger in Flask Socket.io

问题描述

我有一个使用Flask和FlaskSocket.IO 2.8.4的应用程序.初始化SocketIO时，我正在使用

I have an application using Flask and FlaskSocket.IO 2.8.4. When I initialise SocketIO, I am using

#[...]

logging.basicConfig(level=logging.DEBUG,format='[%(asctime)s][%(levelname)s] - %(funcName)s: %(message)s')
logger = logging.getLogger(__name__)
handler = logging.FileHandler(__builtin__.config['dir']['log_file_handler'])
handler.setLevel(logging.DEBUG)
formatter = logging.Formatter('[%(asctime)s][%(levelname)s] - %(funcName)s: %(message)s')
handler.setFormatter(formatter)
logger.addHandler(handler)

# Setting up flask external plugins
socketio = SocketIO(app, logger = False)

#[...]

if __name__ == '__main__':
socketio.run(app, port=8000)

无论如何，我的日志中的输出有很多emit，receive和handle_event行:

Anyway, the output in my log has a lot of emit, receive and handle_event lines:

[2017-04-19 05:17:02,172][INFO] - receive: 1139f764dbe64a1ba6e1c8d95228400c: Received packet MESSAGE data 2/telescope,["AskForTimeEvent"]
[2017-04-19 05:17:02,173][INFO] - _handle_event: received event "AskForTimeEvent" from 1139f764dbe64a1ba6e1c8d95228400c [/telescope]
[2017-04-19 05:17:02,173][INFO] - emit: emitting event "clockEvent" to all [/telescope]
[2017-04-19 05:17:02,174][INFO] - send: 1139f764dbe64a1ba6e1c8d95228400c: Sending packet MESSAGE data 2/telescope,["clockEvent",{"hr":5,"sec":2,"min":17}]
[2017-04-19 05:17:03,287][INFO] - receive: 1139f764dbe64a1ba6e1c8d95228400c: Received packet MESSAGE data 2/telescope,["AskForTimeEvent"]
[2017-04-19 05:17:03,287][INFO] - _handle_event: received event "AskForTimeEvent" from 1139f764dbe64a1ba6e1c8d95228400c [/telescope]
[2017-04-19 05:17:03,288][INFO] - emit: emitting event "clockEvent" to all [/telescope]
[2017-04-19 05:17:03,288][INFO] - send: 1139f764dbe64a1ba6e1c8d95228400c: Sending packet MESSAGE data 2/telescope,["clockEvent",{"hr":5,"sec":3,"min":17}]

我以这种方式使用emit函数:

I am using the emit function this way:

# this inside a function of an arbitrary class, works fine, but writes a lot of log!
with self.app.test_request_context('/telescope'):
        self.socketio.emit('someEvent', json.dumps(arr), namespace='/telescope')

我认为在实例化SocketIO对象时使用参数logger=False可以防止出现这些重复性较大的消息，但事实并非如此.如果有人可以帮助我，我将非常感激.

I would think that the argument logger=False when instantiating the SocketIO object prevents these big repetitive messages, but it doesn't. I would be very thankful if someone can help me with this.

添加的信息:socketio.run时我已经尝试使用选项log_output=False，但是结果完全相同.

Added info: I already tried with the option log_output=False when socketio.run, but the result is exactly the same.

推荐答案

您应用的日志记录更改不起作用的原因是，您通过logging.basicConfig应用的全局更改具有优先权.

The reason the logging changes you are applying don't work is that the global changes you've applied via logging.basicConfig take precedence.

在这里，您可以覆盖这些默认值，仅用于Socket.IO记录器:

Here is how you can override those defaults, just for the Socket.IO logger:

logging.getLogger('socketio').setLevel(logging.ERROR)
logging.getLogger('engineio').setLevel(logging.ERROR)

这会将两个软件包都设置为仅记录错误.

This will set both packages to log only errors.
