小企业网站建设公司哪家好/百度推广费用一年多少钱

淘宝商品详情查询 API（item_detail）主要用于获取淘宝商品的详细信息，以下是相关介绍：

1. 请求参数：
   • num_iid：必填参数，代表商品的唯一标识 ID。通过该 ID 可以准确地指定要查询的商品。例如，你想要查询某个特定的手机商品详情，就需要获取该手机商品的 num_iid 并传入接口。
   • is_promotion：可选参数，用于指定是否获取促销价信息。如果设置为 true，接口返回的信息中会包含商品的促销价格等相关促销信息；如果设置为 false（或不设置该参数），则可能只返回商品的常规价格信息6。
2. 响应参数：
   • item：包含宝贝的详细数据，是一个复杂的结构体，里面包含众多子参数。
     • num_iid：商品的唯一 ID，与请求参数中的 num_iid 相对应，用于确认返回的商品信息是否正确。
     • title：商品的标题，简洁明了地描述商品的名称或主要特点。比如 “华为 P50 智能手机” 等。
     • desc_short：商品的简短描述，通常是对商品的核心特点或优势的简要概括。
     • promotion_price：商品的优惠价，如果商品有促销活动，该价格就是促销后的价格。
     • price：商品的价格，可能是原价或者当前的非促销价格。
     • original_price：商品的原价，用于与促销价等进行对比，让用户了解商品价格的变化。
     • nick：卖家的昵称，帮助买家了解商品的卖家信息。
     • num：商品的库存数量，告知买家该商品目前的可购买数量。
     • min_num：最小购买数，即购买该商品时最少需要购买的数量限制。
     • detail_url：商品的详情链接，点击该链接可以跳转到淘宝商品的详细页面。
     • pic_url：商品的图片链接，通过该链接可以获取到商品的图片，方便买家查看商品的外观等信息。
     • brand：商品的品牌名称，对于品牌商品，该参数可以帮助买家快速了解商品的品牌信息。
     • brandid：品牌的唯一标识 ID，方便系统对品牌进行识别和管理。
     • rootcatid：商品的顶级分类 ID，用于确定商品所属的大分类，如电子产品、服装等。
     • cid：商品的子分类 ID，在顶级分类的基础上进一步细分商品的具体类别。
     • created_time：商品的创建时间，记录了商品在淘宝平台上的创建日期和时间。
     • modified_time：商品的修改时间，当卖家对商品信息进行修改时，该时间会更新。
     • delist_time：商品的下架时间，如果商品已经下架，该参数会记录下架的时间。
     • desc：商品的详细描述，包含商品的详细介绍、功能、使用方法、材质等详细信息。
     • item_imgs：商品的图片列表，可能包含商品的多角度展示图片、细节图片等。
     • props_name：商品的属性名，例如颜色、尺寸、型号等属性的名称和对应的值6。
     • skus：商品的规格信息列表，包含不同规格（如不同颜色、尺寸等）的商品的具体信息，如价格、库存等。
3. 调用流程：
   • 注册账号并创建应用：首先需要在淘宝开放平台进行账号注册、实名认证，并创建应用以获取 appkey 和 appsecret，这是调用 API 接口的必要凭证。
   • 获取 sessionkey：通过淘宝 API 文档中的应用接口获取淘宝用户的授权信息来获取 sessionkey。
   • 构造 API 请求 URL：将调用 API 接口所需的参数、appkey 以及 sessionkey 等信息按照要求进行组合，并对请求参数进行签名（签名算法过程中需要使用 appsecret 以确保数据安全），最终得到 API 的请求 URL。
   • 发送 API 请求：使用 HTTP 的 GET 或 POST 方式将请求参数发送到淘宝开放平台。
   • 解析 API 返回结果：API 返回的结果是 JSON 格式的数据，使用相应的 JSON 解析工具对返回结果进行解析，从中获取所需的商品信息。
