| `target`          | 可直接使用附加本地化选项访问任何 Target URL。                                                                | 否     |
| `target_search`   | [**搜索页面**](/api-targets/cn/dian-zi-shang-wu/target/search.md) ，用于您选择的搜索词。                   | 是     |
| `target_product`  | [**商品页面**](/api-targets/cn/dian-zi-shang-wu/target/product.md) ，用于您选择的商品 ID。                | 是     |
| `target_category` | [**类别页面**](/api-targets/cn/dian-zi-shang-wu/target/category.md) 基于 Target 的 taxonomy 节点 ID。 | 否     |

我们在示例中使用同步 [**Realtime**](/products/cn/web-scraper-api/integration-methods/realtime.md) 集成方法。如果您想使用 [**Proxy Endpoint**](/products/cn/web-scraper-api/integration-methods/proxy-endpoint.md) 或异步 [**Push-Pull**](/products/cn/web-scraper-api/integration-methods/push-pull.md) 集成，请参阅 [**集成方法**](/products/cn/web-scraper-api/integration-methods.md) 部分。

可选地，您还可以包含其他参数，例如 `user_agent_type`, `parse`, `render` 以及更多内容，以自定义您的抓取请求。阅读更多：

## Target 源

target 源允许你通过提供直接 URL 来检索任何 Target 页面。这对于访问 specialized sources 未覆盖的特定 Target 页面很有用。

# 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.md?ask=<question>
```

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.
