# 网页解锁器是否具有 JavaScript 渲染功能？

了解如何在网页解锁器中启用服务器端 JavaScript 渲染。

是的，使用网页解锁器时， [JavaScript 渲染](https://developers.oxylabs.io/products/web-scraper-api/features/js-rendering-and-browser-control#javascript-rendering) 会在我们这边执行，所以你不必担心。你无需自己设置无头浏览器，而是可以在请求中包含 `X-Oxylabs-Render` 头，值可以是 `html` 或 `png` 。响应数据随后会相应地返回 HTML 输出或 PNG 截图（取决于传入的参数）。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://developers.oxylabs.io/help-center/cn/chan-pin-yu-gong-neng/does-web-unblocker-have-javascript-rendering.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
