亚马逊robots协议解析
1. robots协议
Robots协议（也称为爬虫协议、机器人协议等）的全称是“网络爬虫排除标准”（Robots Exclusion Protocol），网站通过Robots协议告诉搜索引擎哪些页面可以抓取，哪些页面不能抓取。robots.txt文件是一个文本文件，使用任何一个常见的文本编辑器，就可以创建和编辑它。robots.txt是一个协议，而不是一个命令。robots.txt是搜索引擎中访问网站的时候要查看的第一个文件。robots.txt文件告诉蜘蛛程序在服务器上什么文件是可以被查看的。

#禁止访问爬取以上目录文件
亚马逊的robots协议相当详细，禁止了相当多有关顾客、商品等的访问，在此robots.txt中，仅允许访问部分wishlist指定文件，个人猜测是通过这些允许爬取的文件，通过浏览器，从浏览器向用户推送相关商品信息，引导用户访问。
