使用方法 retry库提供了一种简单的装饰器(decorator)方法来实现重试功能。下面是使用retry库的基本形式: fromretryimportretryimportrequests@retry(Exception,tries=3,delay=2)deffetch_data(url):response=requests.get(url)response.raise_for_status()# 如果响应状态码不是200,将引发异常returnresponse.json()# 使用...

可是后来发现,python 中有retry这个库,只要安装就可以了。 pip install retry 其中的解释如下: def retry(exceptions=Exception, tries=-1, delay=0, max_delay=None, backoff=1, jitter=0, logger=logging_logger): """Return a retry decorator.
装饰器是 Python 中的一种函数,能够在代码运行时动态地增加功能。装饰器本质上是一个函数,它接受另一个函数作为参数并返回一个新的函数。我们通常使用@decorator_name的语法来应用装饰器。 为什么需要重试机制? 在接口自动化测试中,调用外部接口可能会受到很多因素的影响,导致请求失败。为了提升测试的稳定性,我们可以...
