基于python实现有入参的重试机制装饰器

import logging
import wrapt
import sys
import time
def retry(
        retries=3, exceptions=Exception,
        delay=1, max_delay=60, backoff=2,
        logger=None, log_level=logging.ERROR,log_extra=None
):
    @wrapt.decorator
    def _wrapper(wrapped, instance, args, kwargs):
        _delay = delay
        _retries = sys.maxsize if retries == -1 else retries
        for tries in range(_retries+1):
            try:
                return wrapped(*args, **kwargs)
            except Exception as exc:
                if isinstance(exc, KeyboardInterrupt):
                    raise
                if logger:
                    logger.log(log_level, str(exc), exc_info=True, extra=log_extra)
                if tries >= _retries:
                    raise
                time.sleep(_delay)
                _delay = min(_delay * backoff, max_delay)
    return _wrapper
