使用 watchtower 的 Django 日志记录在处理程序中得到了一个意外的关键字参数

Question

我正在尝试使用 AWS CloudWatch 实现 django 日志记录，在创建用户并输入正确的字段后，按照网上散布的指南，我仍然遇到错误：

ValueError: Unable to configure handler 'watchtower': __init__() got an unexpected keyword argument 'boto3_session'

这是我的设置文件（日志配置）：

boto3_connect_session = Session(
    aws_access_key_id=AWS_ACCESS_KEY_ID,
    aws_secret_access_key=AWS_SECRET_ACCESS_KEY,
    region_name=AWS_REGION_NAME
)


LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'formatters': {
        'aws': {
            'format': u"%(asctime)s [%(levelname)-8s] %(message)s [%(pathname)s:%(lineno)d]",
            'datefmt': "%Y-%m-%d %H:%M:%S"
        },
        'simple': {
            'format': '[%(asctime)s %(module)s] %(levelname)s: %(message)s'
        },

    },
    'handlers': {
        'watchtower': {
            'level': 'DEBUG',
            'class': 'watchtower.CloudWatchLogHandler',
            'boto3_session': boto3_connect_session,
#                     'log_group': AWS_LOG_GROUP,
#                     'stream_name': AWS_LOG_STREAM,
            'formatter': 'aws',
        },
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': '/tmp/logger.log',
            'formatter':'simple'
        },

    },
    'loggers': {
        AWS_LOGGER_NAME: {
            'level': 'DEBUG',
            'handlers': ['watchtower'],
            'propagate': False,
        },
        'local': {
            'level': 'DEBUG',
            'handlers': ['file'],
            'propagate': False,
        },

    },
}

瞭望塔版本：

Name: watchtower
Version: 3.0.0

boto3 版本：

Name: boto3
Version: 1.13.3

我想不通问题出在哪里，大部分导游都用这个系统

提前致谢。

在官方的doc for watchtower with Django中，

中没有提到boto3_session

'watchtower': {
            'level': 'DEBUG',
            'class': 'watchtower.CloudWatchLogHandler',
            'boto3_session': boto3_connect_session,
#                     'log_group': AWS_LOG_GROUP,
#                     'stream_name': AWS_LOG_STREAM,
            'formatter': 'aws',
        },

文档有 boto3_client 而不是 boto3_session

你能核对一下吗？
