# 下载器

该 `youtube_download` 该数据源提供您所选 YouTube 视频的音频/视频内容。请注意，由于数据量可能较大，此数据源仅可通过异步 [**Push-Pull 集成**](/products/cn/web-scraper-api/integration-methods/push-pull.md) 以及 [**云存储**](/products/cn/web-scraper-api/features/result-processing-and-storage/cloud-storage.md) 功能。

## YouTube Downloader 的工作原理

1. 通过 API 提交：
   * 一个或多个 YouTube 视频 ID；
   * 云存储详情。
2. 获取 API 响应，其中确认您的视频下载请求已成功接受。
3. 视频一经我们的系统处理完毕，即会保存到指定的云存储位置。

{% hint style="success" %}
**注意**:

* 下载器默认使用 720p 视频分辨率。如果 720p 不可用，下载器会选择低于 720p 的最佳可用质量。您可以通过使用 `上下文：video_quality`参数。
* 您最多可以下载 12 小时长的视频。
* 下载时间限制为 1 小时。

```javascript
import fetch from 'node-fetch';

const username = 'YOUR_USERNAME';
const password = 'YOUR_PASSWORD';

const payload = {
    source: 'youtube_download',
    query: ['9cQBNYsCqQs', 'KGOsWPF4Wfs'],
      context: [
        { key: "download_type", value: "video" },
        { key: "video_quality", value: "1080"},
      ]
    storage_type: 's3',
    storage_url: 'your-s3-bucket/your-folder/'
};

const response = await fetch('https://data.oxylabs.io/v1/queries/batch', {
    method: 'post',
    body: JSON.stringify(payload),
    headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Basic ' + Buffer.from(`${username}:${password}`).toString('base64'),
    }
});

console.log(await response.json());
```

{% endtab %}
{% endtabs %}

API 会返回一个 JSON 对象，其中包含每个已创建任务的任务信息。任务状态将为 **`pending`** ，直到下载完成。

## 检查任务状态

如果您提供了有效的 [**回调 URL**](/products/cn/web-scraper-api/integration-methods/push-pull.md#callback) 在提交任务时，我们会在完成后通过发送一个 `JSON` 负载到指定的回调 URL。&#x20;

但是，如果您在未使用 [**回调服务**](/products/cn/web-scraper-api/integration-methods/push-pull.md#callback)，您可以手动检查任务状态。请从 `href` 字段中的 `rel:self` 任务提交后收到的响应消息的部分中获取。检查任务状态的 URL 将类似于以下内容： `http://data.oxylabs.io/v1/queries/12345678900987654321`. 查询此 URL 将返回任务信息，包括其当前 `状态`.

### 端点 <a href="#endpoint-1" id="endpoint-1"></a>

```
GET https://data.oxylabs.io/v1/queries/{id}
```

## 部分下载（裁剪）

要下载特定片段或剪辑而不是完整视频，请向您的 `上下文` 数组：

* `start_at` – 裁剪片段的开始时间戳，位于 `hh:mm:ss` 格式。
* `end_at` – 裁剪片段的结束时间戳，位于 `hh:mm:ss` 格式。

{% hint style="warning" %}
`end_at` 时间戳值必须晚于 `start_at`。仅 `hh:mm:ss` 支持该格式。
{% endhint %}

```json
{
    "source": "youtube_download",
    "query": "0xFXmJgVgzc",
    "context": [
        {
            "key": "start_at",
            "value": "00:01:30"
        },
        {
            "key": "end_at",
            "value": "00:05:45"
        }
    ],
    "storage_type": "s3",
    "storage_url": "s3://your-s3-bucket/your-folder/"
}
```

{% hint style="info" %}
如果同时省略这两个参数，请求将按标准完整视频下载处理。
{% endhint %}

如果 `start_at` 或 `end_at` 未通过验证，HTTP `400` 错误将返回，并带有一个 `消息` 字段。

<table><thead><tr><th width="271">条件</th><th>错误信息</th></tr></thead><tbody><tr><td><code>start_at</code> 不在 <code>hh:mm:ss</code> 格式</td><td><code>上下文中的 start_at 值无效。支持的格式：hh:mm:ss。</code></td></tr><tr><td><code>end_at</code> 不在 <code>hh:mm:ss</code> 格式</td><td><code>上下文中的 end_at 值无效。支持的格式：hh:mm:ss。</code></td></tr><tr><td><code>end_at</code> 不晚于 <code>start_at</code></td><td><code>上下文中的 end_at 值无效。必须晚于 start_at。</code></td></tr></tbody></table>

## 云存储

您可以将 YouTube 视频传送到 [**Google Cloud Storage**](#google-cloud-storage-setup), [**Amazon S3**](#amazon-s3-setup), [**Alibaba Cloud OSS**](#alibaba-cloud-oss-setup), 或 [**其他兼容 S3 的云存储**](#s3-compatible-storage-setup).

内容文件将出现在您的云存储位置，并将按以下命名方案之一命名：

* `{video_id}_{job_id}.mp4` – 用于视频
* `{video_id}_{job_id}.m4a` – 用于音频

### 存储参数

<table><thead><tr><th width="170.03125">参数</th><th width="263.372304199773">描述</th><th>有效值</th></tr></thead><tbody><tr><td><code>storage_type</code></td><td>您的云存储类型。</td><td><p><code>gcs</code> (Google Cloud Storage);</p><p><code>s3</code> (AWS S3);<br><code>s3_compatible</code> (其他兼容 S3 的存储解决方案)。</p></td></tr><tr><td><code>storage_url</code></td><td>您的云存储 URL</td><td><p>任何 <code>s3</code> 或 <code>gcs</code> 存储桶名称；</p><p>任何 <code>兼容 S3</code> 存储 URL。</p></td></tr></tbody></table>

### **Google Cloud Storage 设置** <a href="#google-cloud-storage-setup" id="google-cloud-storage-setup"></a>

要将任务结果上传到您的 Google Cloud Storage 存储桶，请 **为我们的服务设置特殊权限** 如我们的 [Google Cloud Storage 文档](/products/cn/web-scraper-api/features/result-processing-and-storage/cloud-storage.md#google-cloud-storage).

```json
{
    "source": "youtube_download",
    "query": "9cQBNYsCqQs",
    "storage_type": "gcs",
    "storage_url": "bucket_name/path"
}
```

### Amazon S3 设置

要将任务结果上传到您的 Amazon S3 存储桶，请为我们的服务设置访问权限。为此，请前往 [**https://s3.console.aws.amazon.com/**](https://s3.console.aws.amazon.com/) → **`S3`** → **`存储`** → **`存储桶名称`**` ``（如果您没有，请创建一个新的）` → **`权限`** → **`存储桶策略`**。您可以在我们的 [Amazon S3 云文档](/products/cn/web-scraper-api/features/result-processing-and-storage/cloud-storage.md#amazon-s3).

请使用下面的存储桶策略（别忘了更改下方的存储桶名称 `YOUR_BUCKET_NAME`):

```json
{
    "Version": "2012-10-17",
    "Id": "Policy1577442634787",
    "Statement": [
        {
            "Sid": "Stmt1577442633719",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::324311890426:user/oxylabs.s3.uploader"
            },
            "Action": "s3:GetBucketLocation",
            "Resource": "arn:aws:s3:::YOUR_BUCKET_NAME"
        },
        {
            "Sid": "Stmt1577442633719",
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::324311890426:user/oxylabs.s3.uploader"
            },
            "Action": [
                "s3:PutObject",
                "s3:PutObjectAcl"
            ],
            "Resource": "arn:aws:s3:::YOUR_BUCKET_NAME/*"
        }
    ]
}
```

此策略允许我们向您的存储桶写入内容，让您访问已上传的文件，并了解存储桶的位置。

### Alibaba Cloud OSS 设置

为了将结果保存到您的 Alibaba Cloud 对象存储服务 (OSS)，您必须创建 `ACCESS_KEY_ID` 和 `ACCESS_KEY_SECRET` 并使用它们来构造存储 URL。请按照我们的 [Alibaba Cloud OSS 文档 ](/products/cn/web-scraper-api/features/result-processing-and-storage/cloud-storage.md#alibaba-cloud-object-storage-service-oss).

```json
{
    "source": "youtube_download",
    "query": "9cQBNYsCqQs",
    "storage_type": "s3_compatible",
    "storage_url": "https://ACCESS_KEY_ID:ACCESS_KEY_SECRET@BUCKET_NAME.oss-REGION.aliyuncs.com/FOLDER_NAME"
}
```

### 兼容 S3 的存储设置

如果您希望将结果传送到 [其他兼容 S3 的存储](/products/cn/web-scraper-api/features/result-processing-and-storage/cloud-storage.md#other-s3-compatible-storage) 位置，您需要包含您的存储桶的 `ACCESS_KEY:SECRET` 认证字符串在 `storage_url` payload 中的值：

```json
{
    "source": "youtube_download",
    "query": "9cQBNYsCqQs",
    "storage_type": "s3_compatible",
    "storage_url": "https://ACCESS_KEY:SECRET@s3.oxylabs.io/my-videos"
}
```

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers.oxylabs.io/api-targets/cn/shi-pin-yu-she-jiao-mei-ti/youtube/youtube-downloader.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
