视频网站xvideo爬虫代码（Python），亲测好用，哈哈哈哈
喜欢的赶紧拿去吧！
随着网络的迅速发展，万维网成为大量信息的载体，如何有效地提取并利用这些信息成为一个巨大的挑战。搜索引擎（Search Engine），例如传统的通用搜索引擎AltaVista，Yahoo!和Google等，作为一个辅助人们检索信息的工具成为用户访问万维网的入口和指南。但是，这些通用性搜索引擎也存在着一定的局限性，如：
（1）不同领域、不同背景的用户往往具有不同的检索目的和需求，通过搜索引擎所返回的结果包含大量用户不关心的网页。
（2）通用搜索引擎的目标是尽可能大的网络覆盖率，有限的搜索引擎服务器资源与无限的网络数据资源之间的矛盾将进一步加深。
（3）万维网数据形式的丰富和网络技术的不断发展，图片、数据库、音频、视频多媒体等不同数据大量出现，通用搜索引擎往往对这些信息含量密集且具有一定结构的数据无能为力，不能很好地发现和获取。

（4）通用搜索引擎大多提供基于关键字的检索，难以支持根据语义信息提出的查询。
为了解决上述问题，定向抓取相关网页资源的聚焦爬虫应运而生。聚焦爬虫是一个自动下载
