[**更多信息**](/products/cn/web-scraper-api/features/js-rendering-and-browser-control.md#javascript-rendering)**.** | - | | `callback_url` | 回调端点的 URL。 [**更多信息**](/products/cn/web-scraper-api/integration-methods/push-pull.md) | - | | `user_agent_type` | 设备类型和浏览器。完整列表可在 [**这里**](/products/cn/web-scraper-api/features/http-context-and-job-management/user-agent-type.md). | desktop | \- 必填参数 ### 本地化 将结果适配到特定商店、履约类型和配送地点。 | 参数 | 描述 | 类型 | | ------------------ | ---------------------------------------------------------------- | --- | | `fulfillment_type` | 设置履约类型。可用值有：pickup、shipping、shop\_in\_store、same\_day\_delivery。 | 字符串 | | `store_id` | 设置门店位置。 | 整数 | | `delivery_zip` | 设置配送至的位置。 | 字符串 | ## 了解 Target 的节点 ID Target 的分类系统使用节点 ID 来标识特定分类。这些节点 ID 是 Target 分类系统中的唯一标识符。 ### 示例节点 ID 节点 ID 可在分类页面 URL 中找到。它是 URL 中符合以下格式的部分 `N-<5 个符号>` 。以下是一些示例分类 URL 及其对应的节点 ID： 1. PlayStation 5 控制器： `owq2q` * 完整 URL： 2. PlayStation 5 配件： `lbxgt` * 完整 URL： 3. PlayStation 5： `hj96d` * 完整 URL：
### 节点 ID 格式 当使用 `target_category` source 时，你只需要提供节点 ID，而不需要提供 `N-` 前缀。API 会自动正确格式化 URL。 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://developers.oxylabs.io/api-targets/cn/dian-zi-shang-wu/target/category.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
