django：如何為SuspiciousOperation異常創建自定義日志記錄篩選器？

Question

從1.8遷移到1.11（從1.8）后，我從日志記錄中收到一些SuspiciousOperation錯誤。

似乎來自JS請求，如果用戶移動鼠標，該請求可使會話保持活動狀態。 但這並不重要。

如何僅過濾此異常？

我試過的

我剛剛在某個地方創建了一個過濾器：

import logging

from django.core.exceptions import SuspiciousOperation

class StopSuspiciousOperation(logging.Filter):
    def filter(self, record):
        if record.exc_info:
            exc_value = record.exc_info[1]
            return isinstance(exc_value, SuspiciousOperation)
        return True

然后，我將此過濾器添加到配置中：

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse',
        },
        'stop_suspicious_operation': {
            '()': 'aula.utils.loggingFilters.StopSuspiciousOperation',
        }
    },
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false',
                        'stop_suspicious_operation',], #<-- here
            'class': 'django.utils.log.AdminEmailHandler'
        }
    },
    'loggers': {
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },
    }
}

但是我仍然收到錯誤：

內部服務器錯誤：/ keepalive

SuspiciousOperation at /keepalive
The request's session was deleted before the request completed. The user may have logged out in a concurrent request, for example.

Request Method: GET
Request URL: https://XXXXXX/YYYYYY
Django Version: 1.11.9
Python Executable: /usr/bin/python
Python Version: 2.7.3

我不確定正確的答案，但是我認為django在WSGI級別上正在捕獲SuspiciousOperation，並且正在記錄錯誤。 參見： https : //docs.djangoproject.com/en/dev/ref/exceptions/#suspiciousoperation

如果SuspiciousOperation異常達到WSGI處理程序級別，則將其記錄為錯誤級別，並導致HttpResponseBadRequest。

您可能只想過濾出這樣的錯誤請求：

from logging import LogRecord


def filter_400(record: LogRecord) -> bool:
    '''Filter out HTTP Error Code 400 Bad Request'''
    return record.status_code != 400
