前言

用Django REST framework来构建Restful API，需要记录用户请求的时间、方法、数据、响应状态等.

实现方法

用Python的logging模块

在配置文件中写入settings

# LOGGING setting
LOG_DIR = BASE_DIR + "/logs"
if not os.path.exists(LOG_DIR):
    os.mkdir(LOG_DIR)

LOGGING = {
    'version': 1,
    'disable_existing_loggers': True,
    'formatters': {
        'standard': {
            'format': '%(asctime)s FuncName:%(funcName)s LINE:%(lineno)d [%(levelname)s]- %(message)s'
        },
        'simple': {
            'format': '%(levelname)s %(message)s'
        },
        'verbose': {
            'format': '%(levelname)s %(asctime)s %(module)s %(funcName)s %(message)s'
        },
    },
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse'
        }
    },
    'handlers': {
        'console': {
            'level': 'DEBUG',
            'class': 'logging.StreamHandler',
            'formatter': 'standard'
        },
        'default': {
            'level': 'INFO',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': os.path.join(LOG_DIR, 'info.log'),
            'maxBytes': 1024 * 1024 * 50,  # 50 MB
            'backupCount': 2,
            'formatter': 'standard',
        },
        'default_debug': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': os.path.join(LOG_DIR, 'debug.log'),
            'maxBytes': 1024 * 1024 * 50,  # 50 MB
            'backupCount': 2,
            'formatter': 'standard',
        },
        'request_handler': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': os.path.join(LOG_DIR, 'common.log'),
            'maxBytes': 1024 * 1024 * 50,  # 50 MB
            'backupCount': 2,
            'formatter': 'standard',
        },
        'restful_api': {
            'level': 'DEBUG',
            'class': 'logging.handlers.RotatingFileHandler',
            'filename': os.path.join(LOG_DIR, 'api.log'),
            'maxBytes': 1024 * 1024 * 50,  # 50 MB
            'backupCount': 2,
            'formatter': 'verbose',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console', 'default_debug'],
            'level': 'INFO',
            'propagate': False
        },
        'django.request': {
            'handlers': ['request_handler'],
            'level': 'INFO',
            'propagate': False
        },
        'common': {
            'handlers': ['default', 'console'],
            'level': 'INFO',
            'propagate': True
        },
        'api': {
            'handlers': ['restful_api'],
            'level': 'INFO',
            'propagate': True
        },
    }
}

编写中间件

import logging
import json


class ApiLoggingMiddleware(object):
    def __init__(self, get_response):
        self.get_response = get_response
        self.apiLogger = logging.getLogger('api')

    def __call__(self, request):
        try:
            body = json.loads(request.body)
        except Exception:
            body = dict()
        body.update(dict(request.POST))
        response = self.get_response(request)
        if request.method != 'GET':
            self.apiLogger.info("{} {} {} {} {} {}".format(
                request.user, request.method, request.path, body,
                response.status_code, response.reason_phrase))
        return response

添加配置

MIDDLEWARE = [
    ---
    'middlewares.middleware.ApiLoggingMiddleware'
]
