视图使用

def log(request):
    """
    `django` 日志系统

    文档参见: https://docs.djangoproject.com/en/1.11/topics/logging/
    """
    import logging
    logger = logging.getLogger('django.request')
    logger.error("错误信息")
    return HttpResponse("OK")

重写log输出模式

• 在配置中进行导入

import json
import logging
import datetime

REMOVE_ATTR = [
    "filename", "module", "exc_text", "stack_info", "created", "relativeCreated", "exc_info", "msg",
    "request",
]

class JSONFormatter(logging.Formatter):

    def format(self, record):
        extra = self.build_record(record)

        self.set_format_time(extra)  # set time
        # self.set_host_ip(extra)  # set host name and host ip
        extra['message'] = record.msg  # set message
        if record.exc_info:
            extra['exc_info'] = self.formatException(record.exc_info)
        if self._fmt == 'pretty':
            return json.dumps(extra, indent=1, ensure_ascii=False)
        else:
            return json.dumps(extra, ensure_ascii=False)

    @classmethod
    def build_record(cls, record):
        record = {
            attr_name: record.__dict__[attr_name]
            for attr_name in record.__dict__
            if attr_name not in REMOVE_ATTR
        }
        return record

    @classmethod
    def set_format_time(cls, extra):
        now = datetime.datetime.now()
        format_time = now.strftime("%Y-%m-%d %H:%M:%S")
        extra['timestamp'] = format_time
        return format_time
