news2025/2/23 3:36:56

logging打印日志，文件名为log_config.py

import logging
import sys

def setup_logger(log_file, error_log_file):
    # 创建一个日志记录器
    logger = logging.getLogger(__name__)
    logger.setLevel(logging.DEBUG)  # 设置全局日志级别为 DEBUG

    # 创建一个文件处理器，将日志写入文件
    file_handler = logging.FileHandler(log_file)
    file_handler.setLevel(logging.DEBUG)  # 设置文件日志级别为 DEBUG

    # 创建一个错误文件处理器，将错误日志单独写入文件
    error_file_handler = logging.FileHandler(error_log_file)
    error_file_handler.setLevel(logging.ERROR)  # 设置错误文件日志级别为 ERROR

    # 创建一个控制台处理器，将日志输出到控制台
    console_handler = logging.StreamHandler(sys.stdout)
    console_handler.setLevel(logging.DEBUG)  # 设置控制台日志级别为 DEBUG

    # 创建一个日志格式化对象
    formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')

    # 将格式化应用到处理器
    file_handler.setFormatter(formatter)
    error_file_handler.setFormatter(formatter)
    console_handler.setFormatter(formatter)

    # 将处理器添加到日志记录器
    logger.addHandler(file_handler)
    logger.addHandler(error_file_handler)  # 将错误文件处理器添加到日志记录器
    logger.addHandler(console_handler)

    return logger

邮件发送，导入log_config.py配置

from email.header import Header

#logger = log_config.setup_logger('mail.log','error_mail.log')

    smtp_port = 25

    username = '18847097110@163.com'

    msg = MIMEText(body, 'plain', 'utf-8')
    msg['From'] = from_address
    msg['To'] = to_address
    msg['Subject'] = Header(subject, 'utf-8')


    logger = log_config.setup_logger('mail.log','error_mail.log')  #引用log_confog.py里的setup_logger
    server = None

    try:
        sock = socket.create_connection((smtp_server, smtp_port), timeout=5)
        sock.close()

        server = smtplib.SMTP(smtp_server, smtp_port)
        server.login(username, password)
        server.sendmail(from_address, to_address, msg.as_string())
        logger.info('Email sent successfully!')

    except socket.error as e:

    finally:
        if server is not None:
            server.quit()
