在对源代码不进行修改的情况下,可以用装饰器来进行重试 任何函数: 成功,返回-结果,失败,返回--False 都可以用这个装饰器进行重试 1.不需要传参的装饰器写法: max_retry 为默认重试的次数 = 3 number = 0 if not ret: while number < max_retry: number = kwargs.get('max_retry') # 不传默认重试3次 if not max_retry: max_retry = kwargs.get('max_retry') # 不传默认重试3次 if not max_retry: max_retry = 3 number = 0 if not ret: while number
