Django日志记录详细的报错信息

当服务器500错误的时候，普通日志只会记录一行500的request信息，并不会记录详细的报错定位

[ERROR] 2019-06-12 15:07:03,597 "GET /api/v1/test/ HTTP/1.1" 500 74196

需要添加一个在日志中记录详细错误信息的middleware

# -*- coding: UTF-8 -*-
import logging

logger = logging.getLogger('default')

class ExceptionLoggingMiddleware(object):
    def process_exception(self, request, exception):
        import traceback
        logger.error(traceback.format_exc())

将此中间件添加到settings的MIDDLEWARE_CLASSES中

MIDDLEWARE_CLASSES = (
'utils.my_middleware.ExceptionLoggingMiddleware',
)

使用Django logger

    'loggers': {
        'django': {
            'handlers': ['file', 'console'],
            'level': 'INFO'
        },

效果
