ASP小偷(远程数据获取)程序的入门教程

admin

<span id="ArticleContent1_ArticleContent1_lblContent">      这里所说的“小偷”指的是在asp中运用xml中的xmlhttp组件提供的强大功能，把远程网站上的数据（图片，网页及其他文件）抓取到本地，经过各种处理后显示到页面上或者存储进数据库的一类程序。你可以通过这种小偷程序，完成过去一些似乎完全不可能实现的任务，比如说把某个站的页面偷梁换柱后变成自己的页面，或者把某个站的一些数据（文章，图片）保存到本地数据库中加以利用。“小偷”的优点有：无须维护网站，因为小偷程序中的数据来自其他网站，它将随着该网站的更新而更新；可以节省大量的服务器资源，一般小偷程序就几个文件，所有网页内容都是来自其他网站。缺点在于：不稳定，如果目标网站出错，程序也会出错，而且，如果目标网站进行升级维护，那么小偷程序也要进行相应修改；速度，因为是远程调用，速度和在本地服务器上读取数据比起来，肯定要慢一些。怎么样，听起来很神奇吧？我们现在就开始来学习一些“小偷”程序的入门知识吧！
