django 自定义日志字段

1.settings.py    MIDDLEWARE  新增中间件  'middleware_log.RequestLogMiddleware'

MIDDLEWARE = [
    ...
    'middleware_log.RequestLogMiddleware'
]

2.settings.py配置  LOGGING

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'standard': {
            'format': '[%(asctime)s][%(threadName)s:%(thread)d][task_id:%(name)s][%(filename)s:%(lineno)d]'
                      '[%(levelname)s][%(message)s]'
        },
        'ops_standard': {
            'format': '%(asctime)s %(ip)s user:%(username)s %(filename)s:%(lineno)d %(levelname)s http_reffer:%('
                      'http_reffer)s path:%(path)s %(message)s '
        },
    },
    'filters': {
        'new_add': {'()': 'middleware_log.RequestLogFilter'},
    },
    'handlers': {
        #
        'default': {
            'level': 'INFO',
            'class': 'logging.handlers.TimedRotatingFileHandler',
            'filename': os.path.join(BASE_LOG_DIR, 'access.log'),
            'backupCount': 5,  # 备份数
            'formatter': 'ops_standard',  # 输出格式
            'encoding': 'utf-8',  # 设置默认编码，否则打印出来汉字乱码
            'filters': ['new_add'],
            'when': 'D',
            'interval': 1,
        },
        'error': {
            'level': 'ERROR',
            'class': 'logging.handlers.TimedRotatingFileHandler',
            'filename': os.path.join(BASE_LOG_DIR, 'error.log'),
            'backupCount': 5,  # 备份数
            'formatter': 'ops_standard',  # 输出格式
            'encoding': 'utf-8',  # 设置默认编码
            'filters': ['new_add'],
            'when': 'D',
            'interval': 1,
        },
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'standard',
        },
        'info': {
            'level': 'INFO',
            'class': 'logging.handlers.TimedRotatingFileHandler',
            'filename': os.path.join(BASE_LOG_DIR, 'info.log'),
            'backupCount': 5,
            'formatter': 'ops_standard',
            'encoding': 'utf-8',  # 设置默认编码
            'filters': ['new_add'],
            'when': 'D',
            'interval': 1,
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console', 'default'],
            'level': 'INFO',
            'propagate': False
        },
        # '' 调用时需要当作参数传入
        '': {
            'handlers': ['error', 'info', 'default'],
            'level': 'INFO',
            'propagate': True
        },
    }
}

3.项目里新增文件

import threading
import logging
 
try:
    from django.utils.deprecation import MiddlewareMixin  # Django 1.10.x
except ImportError:
    MiddlewareMixin = object  # Django 1.4.x - Django 1.9.x
 
local = threading.local()
 
 
class RequestLogFilter(logging.Filter):
    """
    日志过滤器，将当前请求线程的request信息保存到日志的record上下文
    record带有formater需要的信息。
    """
 
    def filter(self, record):
        record.ip = getattr(local, 'ip', None)
        record.username = getattr(local, 'username', None)
        record.http_reffer = getattr(local, 'http_reffer', None)
        record.path = getattr(local, 'path', None)
        return True
 
 
class RequestLogMiddleware(MiddlewareMixin):
    """
    将request的信息记录在当前的请求线程上。
    """
 
    def process_request(self, request):
        temp_meta = request.META
        local.ip = request.META.get('HTTP_X_FORWARDED_FOR', None)
        local.username = xxx
        local.http_reffer = temp_meta.get('HTTP_REFERER', None)
        local.path = temp_meta.get('PATH_INFO', None)
 
    def process_response(self, request, response):
        return response

4.使用

import logging
LOG  = logging.getLogger()
 
 
LOG.info('hahahhahaha')
LOG.error('lalalalala')
