如何动态调整Python爬虫的Request请求延迟

引言在网络爬虫开发中，合理控制请求延迟（Request Delay）是避免被封禁、提高爬取效率的关键。固定延迟（如 time.sleep(1)）虽然简单，但在面对不同网站的反爬策略时可能不够灵活。动态调整请求延迟能够更智能地适应目标网站的变化，提高爬虫的稳定性和效率。本文将介绍如何动态调整Pytho...

如何根据目标网站调整Python爬虫的延迟时间？

一、为什么需要调整爬虫的延迟时间？反爬虫机制的挑战大多数网站（尤其是电商平台如淘宝）都部署了反爬虫机制，用于检测异常的访问行为。如果爬虫的请求频率过高，可能会触发以下反制措施：● IP封禁：短时间内大量请求会导致IP被封禁。● 验证码：频繁访问可能会触发验证码，增加抓取...
