使用 logging.basicConfig() 将自定义处理程序添加到日志根级别

Question

我正在尝试构建一个通过 http 发送日志消息的自定义日志处理程序。但是，我不想添加带有addHandler()方法的处理程序。我希望直接在日志根级别配置自定义处理程序，logging.basicConfig()特别是确保从具有不同记录器的不同模块触发的所有日志消息都通过 http 发送。我怎样才能做到这一点？

这是我当前的代码

"""Entrypoint to execute python scripts."""

import argparse

import logging

import sys

import utils

from batch import Batch

from data_source import DataSource

# Load default logging configuration

logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')

log = logging.getLogger(__name__)

# Define custom log handler

class CustomLogHandler(logging.Handler):

    """Custom logs handler to send log messages to GraphQL API."""

    def __init__(self, authorization: str, batch_id: int):

        logging.Handler.__init__(self)

        self.authorization = authorization

        self.batch_id = str(batch_id)

    def emit(self, log_record):

        file_name = log_record.name

        log_level = log_record.levelname

        log_message = self.format(log_record)

        # Do stuff here...

        utils.execute_graphql_request(self.authorization, mutation)

if __name__ == '__main__':

    parser = argparse.ArgumentParser(description='Entry point to execute data quality scripts.')

    parser.add_argument('authorization', type=str, help='Authentication token of the user')

    parser.add_argument('method', type=str, help='Method to be executed: execute_batch, test_data_source')

    parser.add_argument('id', type=int, help='Id of the object on which to execute the method.')

    arguments = parser.parse_args()

    authorization = arguments.authorization

    method = arguments.method

您有两种方法可以将处理程序添加到根记录器，或者将其添加到basicConfig：    logging.basicConfig(        level=logging.INFO,        format="%(asctime)s [%(levelname)s] %(message)s",        handlers=[            logging.StreamHandler(),            CustomLogHandler()        ]    )或者在完成基本配置后，您可以将其添加到根记录器（以确保传播），如下所示：root_log = logging.getLogger()root_log.addHandler(CustomLogHandler())然后每当你做一个import logginglog = logging.getLogger(__name__)log.info("message")“消息”日志应通过您的根记录器发送。
