电商淘宝京东，精准关键词搜索API接口

当使用电商淘宝京东的精准关键词搜索API接口时，以下是清晰的步骤指南：

一、注册与申请API密钥

注册账号：在淘宝开放平台或京东开放平台注册成为开发者，并创建账号。
创建应用：登录后，在开放平台创建一个应用以获取应用的App Key和App Secret。
通过审核：提交应用信息并等待平台审核通过。审核通过后，你将获得一组API密钥，包括apiKey和apiSecret。

二、查阅API文档

理解接口：仔细阅读京东或淘宝开放平台提供的API文档，了解精准关键词搜索接口（如item_search）的具体信息。
参数说明：了解接口的请求参数、返回参数、调用限制以及示例等信息。特别是要注意关键字（keyword）、页码（page）、每页数量（pageSize）等核心参数。

三、构造请求

设置参数：根据API文档的要求，设置请求参数。例如，你可以设置关键字为“鞋”，页码为1，每页数量为10等。
签名与认证：使用App Key和App Secret生成签名，用于接口请求的身份验证。确保在请求中包含必要的验证信息。
