API接口调用，获取淘宝天猫，拼多多，1688等平台商品详情，python采集爬虫数据_淘宝抓取 api 接口工具

Python技术

爬虫（又称为网页蜘蛛，网络机器人，在 FOAF 社区中间，更经常的称为网页追逐者）；它是一种按照一定的规则，自动地抓取网络信息的程序或者脚本。

如果我们把互联网比作一张大的蜘蛛网，那一台计算机上的数据便是蜘蛛网上的一个猎物，而爬虫程序就是一只小蜘蛛，他们沿着蜘蛛网抓取自己想要的猎物/数据。

网页的请求和响应方式是 Request 和 Response

Request：用户将自己的信息通过浏览器（socket client）发送给服务器（socket server）

Response：服务器接收请求，分析用户发来的请求信息，收到请求信息后返回数据（返回的数据中可能包含其他链接，如：image、js、css等）

浏览器在接收 Response 后，会解析其内容来显示给用户，而爬虫程序在模拟浏览器发送请求然后接收 Response 后，是要提取其中的有用数据。

 获取响应内容，例如 前往注册测试
