京东商品页面数据获取方法，京东 API 批量商品数据抓取示例

京东商城是一个网上购物平台，售卖各类商品，包括服装、鞋类、家居用品、美妆产品、电子产品等。要获取京东商品列表和商品详情页面数据，您可以通过开放平台的接口或者直接访问京东商城的网页来获取商品详情信息。以下是两种常用方法的介绍：

1. 通过京东开放平台接口获取商品列表和详情数据：

首先，您需要在开放平台注册成为开发者并创建一个应用，获取到所需的 App Key 和 App Secret 等信息。
使用获取到的 App Key 和 App Secret，进行签名和认证，获取 Access Token。
调用开放平台提供的接口，传入商品 ID 作为参数，获取对应商品的列表和详情页面数据。
请参考开放平台提供的接口文档，了解相应的接口和参数。

2. 直接访问京东商城网页并解析商品详情数据：

使用 HTTP 请求库，发送 GET 请求到京东商城的商品详情页面，将关键词作为参数传递给 URL。获取到返回的 HTML 页面，根据页面结构和 DOM 操作技术，解析出商品的详细信息，例如标题、价格、销量、库存、描述、图片等。
请注意，直接解析网页可能会受到页面结构和变动的影响，需要自行编写相关的解析逻辑。

以下是一个使用 Java 编写的示例代码，展示如何通过封装 API 获取商品列表数据：
