django - 如何通过日志记录筛选出GET静态和媒体消息？

I'm working on a page that has lots of images so this generates lots of output in the console of this type. In my dev environment I use django to serve static and media, so I get a LOT of this in my console:

我正在处理一个包含大量图像的页面，因此这会在此类型的控制台中生成大量输出。在我的开发环境中，我使用django来提供静态和媒体，所以我在我的控制台中得到了很多：

...
[23/May/2014 12:41:54] "GET /static/css/style.css HTTP/1.1" 304 0
[23/May/2014 12:41:55] "GET /static/js/jquery-1.7.1.min.js HTTP/1.1" 304 0
[23/May/2014 12:41:55] "GET /static/js/jquery.form.js HTTP/1.1" 304 0
...
[23/May/2014 12:41:57] "GET /media/producto/Tapa_Santiago_Vazquez_SV.jpg HTTP/1.1" 304 0
[23/May/2014 12:41:57] "GET /media/CACHE/images/producto/Barcos_y_mariposas_DVD_baja/2e3e3894ca08f88c03459e00f9018427.jpg HTTP/1.1" 304 0
[23/May/2014 12:41:56] "GET /media/CACHE/images/producto/tapaDEJA_VU/fb67e92ffd47808a263db02ca016bc24.jpg HTTP/1.1" 304 0
...

making it very tedious to look for meaningful output.

寻找有意义的输出非常繁琐。

I would like to filter out those messages in my environment so I only see the GET for the view and my output, but so far looking at the logging I saw that I could affect other logging from django but not this. I even tried this but it didn't work:

我想在我的环境中过滤掉那些消息，所以我只看到了视图和输出的GET，但到目前为止看到我看到的日志记录，我可能会影响来自django的其他日志记录但不是这个。我甚至试过这个，但它不起作用：

LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,
    'handlers': {
        'null': {
            'level': 'ERROR',
            'class': 'django.utils.log.NullHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['null'],
            'level': 'ERROR',
            'propagate': True,
        },
    }
}

is it even possible to filter that kind of output out?

甚至可以过滤掉那种输出吗？

Thanks!!

谢谢！！

Recent versions of Django make it really easy to override the default logging with your own LOGGING settings.

最新版本的Django使用您自己的LOGGING设置覆盖默认日志记录非常容易。

To filter out all GET requests to the /static/ directory, add the following to your settings.py:

要过滤掉对/ static /目录的所有GET请求，请将以下内容添加到settings.py：

def skip_static_requests(record):
    if record.args[0].startswith('GET /static/'):  # filter whatever you want
        return False
    return True

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        # use Django's built in CallbackFilter to point to your filter 
        'skip_static_requests': {
            '()': 'django.utils.log.CallbackFilter',
            'callback': skip_static_requests
        }
    },
    'formatters': {
        # django's default formatter
        'django.server': {
            '()': 'django.utils.log.ServerFormatter',
            'format': '[%(server_time)s] %(message)s',
        }
    },
    'handlers': {
        # django's default handler...
        'django.server': {
            'level': 'INFO',
            'filters': ['skip_static_requests'],  # <- ...with one change
            'class': 'logging.StreamHandler',
            'formatter': 'django.server',
        },
    },
    'loggers': {
        # django's default logger
        'django.server': {
            'handlers': ['django.server'],
            'level': 'INFO',
            'propagate': False,
        },
    }
}

Here are all of Django's default loggers as of 1.10, which you can override in the same way: https://github.com/django/django/blob/32265361279b3316f5bce8efa71f2049409461e3/django/utils/log.py#L18

以下是1.10版本中Django的所有默认记录器，您可以用相同的方式覆盖它们：https：//github.com/django/django/blob/32265361279b3316f5bce8efa71f2049409461e3/django/utils/log.py#L18

Here are descriptions of what Django's default built-in loggers do: https://docs.djangoproject.com/en/1.10/topics/logging/#id3

以下是Django默认内置记录器的功能描述：https：//docs.djangoproject.com/en/1.10/topics/logging/#id3

Here's are the docs on Django's CallbackFilter used above to hook in the custom filter: https://docs.djangoproject.com/en/1.10/topics/logging/#django.utils.log.CallbackFilter

以下是关于Django的CallbackFilter的文档，用于挂钩自定义过滤器：https：//docs.djangoproject.com/en/1.10/topics/logging/#django.utils.log.CallbackFilter

As a workaround, you can use this snippet (from Django Snippets):

作为解决方法，您可以使用此代码段（来自Django Snippets）：

from django.conf import settings
from django.core.servers import basehttp
from django.core.management.commands.runserver import Command as BaseCommand

class QuietWSGIRequestHandler(basehttp.WSGIRequestHandler):
    def log_message(self, format, *args):
        # Don't bother logging requests for paths under MEDIA_URL.
        if self.path.startswith(settings.MEDIA_URL):
            return
        # can't use super as base is old-style class, so call method explicitly
        return basehttp.WSGIRequestHandler.log_message(self, format, *args)

def run(addr, port, wsgi_handler):
    server_address = (addr, port)
    httpd = basehttp.WSGIServer(server_address, QuietWSGIRequestHandler)
    httpd.set_app(wsgi_handler)
    httpd.serve_forever()

class Command(BaseCommand):
    def handle(self, addrport='', *args, **options):
        # monkeypatch Django to use our quiet server
        basehttp.run = run
        return super(Command, self).handle(addrport, *args, **options)

You need to user this command to run the server. It basically only override the log behaviour to drop requests which begins by the MEDIA_URL setting. Put this whole file in an installed app and run it with ./manage.py runserver_quiet (if the command file is runserver_quiet.py)

您需要使用此命令来运行服务器。它基本上只覆盖日志行为以删除以MEDIA_URL设置开头的请求。将整个文件放在已安装的应用程序中并使用./manage.py runserver_quiet运行它（如果命令文件是runserver_quiet.py）

You can't play with the logging module, because the WSGIRequestHandler doesn't use it to display these messages. It is directly written in the stderr stream.

您无法使用日志记录模块，因为WSGIRequestHandler不会使用它来显示这些消息。它直接写在stderr流中。

#3

From Django 1.10 you can configure django.server logging for "the handling of requests received by the server invoked by the runserver command". This is a quick way to filter out the media requests and to focus on your logger info.

从Django 1.10开始，您可以将django.server日志记录配置为“处理由runserver命令调用的服务器接收的请求”。这是过滤媒体请求并专注于记录器信息的快速方法。

Add to django logging settings:

添加到django日志记录设置：

loggers: {
....
    'django.server': {
        'handlers': ['console'],
        'level': 'ERROR'  # or INFO if you want to see the log
    },
}

from django.core.servers.basehttp import WSGIRequestHandler

# Grab the original log_message method.
_log_message = WSGIRequestHandler.log_message

def log_message(self, *args):
    # Don't log if path starts with /static/
    if self.path.startswith("/static/"):
        return
    else:
        return _log_message(self, *args)

# Replace log_message with our custom one.
WSGIRequestHandler.log_message = log_message

# Import the original runserver management command
from django.core.management.commands.runserver import Command
