如何在LoggerAdapter实例实例化后添加上下文信息？

import logging
from logging import LoggerAdapter

# 创建底层Logger对象
logger = logging.getLogger(__name__)

# 创建LoggerAdapter实例，并传入Logger对象
adapter = LoggerAdapter(logger, extra={})

extra = {
    'request_id': '123456',
    'user_id': '7890'
}

adapter = LoggerAdapter(logger, extra=extra)

def add_context(record):
    # 获取上下文信息
    request_id = record.extra.get('request_id')
    user_id = record.extra.get('user_id')

    # 添加上下文信息到日志记录
    record.request_id = request_id
    record.user_id = user_id

    return record

adapter.process = add_context

adapter.debug('This is a debug message')
adapter.info('This is an info message')
