前言

小夥伴們大家好，相信近期很多關注的CC的小夥伴肯定都會有一個疑問，就是CC每天更新的API介面具體是什麼，透過它又能如何幫助我們簡化工作呢?

那麼首先我們要理解兩個詞的含義，API介面和資料探勘這兩者分別是什麼，它們兩者之間的關係又是什麼呢?今天CC和大家來聊一聊這個話題，同時也會舉例說明。

part1.API介面和資料探勘分別是什麼

API(Application Programming Interface,應用程式程式設計介面)是一些預先定義的函式，目的是提供應用程式與開發人員基於某軟體或硬體的以訪問一組例程的能力，而又無需訪問原始碼，或理解內部工作機制的細節。API除了有應用“應用程式介面”的意思外，還特指 API的說明檔案，也稱為幫助檔案。

資料探勘就是從大量的資料中去發現有用的資訊，然後根據這些資訊來輔助決策。聽起來是不是跟傳統的資料分析很像呢？實際上，資料探勘就是智慧化的資料分析，它們的目標都是一樣的。但是，又有很大的區別。傳統的資料分析和資料探勘最主要的區別就是在揭示資料之間的關係上。傳統的資料分析揭示的是已知的、過去的資料關係，資料探勘揭示的是未知的、將來的資料關係。它們採用的技術也不一樣，傳統的資料分析採用計算機技術，而資料探勘不僅採用計算機技術，還涉及到統計學、模型演演算法等技術，相對來說會複雜很多。因為資料探勘發現的是將來的資訊，所以最主要就是用來：預測！預測公司未來的銷量，預測產品未來的價格等等。

part2.API介面和資料探勘之間的關係

既然瞭解到了這兩者的含義，那麼我們可以透過他們表面的含義去理解，那就是我們就可以透過API介面去實現資料探勘的這一目的。

part3.示例說明

item_get-獲得淘寶商品詳情

名稱型別必須描述

key String 是呼叫key（必須以GET方式拼接在URL中）

secret String 是呼叫金鑰（介面v=PNG_WNMN)

api_name String 是 API介面名稱（包括在請求地址中）[item_search,item_get,item_search_shop等]

cache String 否 [yes,no]預設yes，將呼叫快取的資料，速度比較快

result_type String 否 [json,jsonu,xml,serialize,var_export]返回資料格式，預設為json，jsonu輸出的內容中文可以直接閱讀

lang String 否 [cn,en,ru]翻譯語言，預設cn簡體中文

version String 否 API版本

請求引數

請求引數：num_iid=652874751412&is_promotion=1

引數說明：num_iid:淘寶商品ID

is_promotion:是否獲取取促銷價

響應引數
