前言

小伙伴们大家好，相信近期很多关注的CC的小伙伴肯定都会有一个疑问，就是CC每天更新的API接口具体是什么，通过它又能如何帮助我们简化工作呢?

那么首先我们要理解两个词的含义，API接口和数据挖掘这两者分别是什么，它们两者之间的关系又是什么呢?今天CC和大家来聊一聊这个话题，同时也会举例说明。

part1.API接口和数据挖掘分别是什么

API(Application Programming Interface,应用程序编程接口)是一些预先定义的函数，目的是提供应用程序与开发人员基于某软件或硬件的以访问一组例程的能力，而又无需访问源码，或理解内部工作机制的细节。API除了有应用“应用程序接口”的意思外，还特指 API的说明文档，也称为帮助文档。

数据挖掘就是从大量的数据中去发现有用的信息，然后根据这些信息来辅助决策。听起来是不是跟传统的数据分析很像呢？实际上，数据挖掘就是智能化的数据分析，它们的目标都是一样的。但是，又有很大的区别。传统的数据分析和数据挖掘最主要的区别就是在揭示数据之间的关系上。传统的数据分析揭示的是已知的、过去的数据关系，数据挖掘揭示的是未知的、将来的数据关系。它们采用的技术也不一样，传统的数据分析采用计算机技术，而数据挖掘不仅采用计算机技术，还涉及到统计学、模型算法等技术，相对来说会复杂很多。因为数据挖掘发现的是将来的信息，所以最主要就是用来：预测！预测公司未来的销量，预测产品未来的价格等等。

part2.API接口和数据挖掘之间的关系

既然了解到了这两者的含义，那么我们可以通过他们表面的含义去理解，那就是我们就可以通过API接口去实现数据挖掘的这一目的。

part3.示例说明

item_get-获得淘宝商品详情

名称类型必须描述

key String 是调用key（必须以GET方式拼接在URL中）

secret String 是调用密钥（接口v=PNG_WNMN)

api_name String 是 API接口名称（包括在请求地址中）[item_search,item_get,item_search_shop等]

cache String 否 [yes,no]默认yes，将调用缓存的数据，速度比较快

result_type String 否 [json,jsonu,xml,serialize,var_export]返回数据格式，默认为json，jsonu输出的内容中文可以直接阅读

lang String 否 [cn,en,ru]翻译语言，默认cn简体中文

version String 否 API版本

请求参数

请求参数：num_iid=652874751412&is_promotion=1

参数说明：num_iid:淘宝商品ID

is_promotion:是否获取取促销价

响应参数

名称类型必须示例值描述
