YouTube 下载器

了解如何使用网页爬虫 API 下载 YouTube 视频和音频内容。了解其参数和云存储设置选项。

该 youtube_download source 提供您选择的 YouTube 视频的音频/视频内容。请注意，由于可能存在的大量数据，此来源仅通过异步 Push-Pull 集成 和 云存储 功能可用。

如需 YouTube 下载器的免费试用，请与我们的 销售团队.

YouTube 下载器的工作原理

通过 API 提交：
- 一个或多个 YouTube 视频 ID；
- 云存储详情。
获取 API 响应，确认您的下载视频请求已成功被接受。
一旦我们系统处理完毕，您即可在指定的云存储位置获取视频。

注意:

下载器默认使用 720p 视频分辨率。如果 720p 不可用，下载器将选择低于 720p 的最佳可用质量。您可以使用 context: video_quality参数来覆盖此行为。
您可以下载最多 12 小时长度的视频。
下载时间限制为 1 小时。

API 将以 JSON 对象响应，包含为每个创建的作业的信息。作业状态将在 pending 直到下载完成为止。

检查作业状态

如果您在提交作业时提供了有效的 回调 URL 我们将在完成时通过向指定的回调 URL 发送一个 JSON 载荷来通知您。

但是，如果您在提交作业时未使用 回调服务，您可以手动检查作业状态。请从提交作业后收到的响应消息的 href 字段中检索 URL，位于 rel:self 部分。用于检查作业状态的 URL 将类似于以下内容： http://data.oxylabs.io/v1/queries/12345678900987654321查询该 URL 将返回作业信息，包括其当前 status.

端点

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

云存储

您可以将 YouTube 视频交付到 Google Cloud Storage, Amazon S3, Alibaba OSS, 或 其他兼容 S3 的云存储.

内容文件将出现在您的云存储位置，并将根据以下其中一种命名模式命名：

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

存储参数

参数

说明

有效值

storage_type

您的云存储类型。

gcs (Google Cloud Storage);

s3 (AWS S3); s3_compatible (其他兼容 S3 的存储解决方案)。

storage_url

您的云存储 URL

任何 s3 或 gcs 存储桶名称；

任何 s3-compatible 存储 URL。

Google Cloud Storage 设置

要将作业结果上传到您的 Google Cloud Storage 存储桶，请为我们的服务 设置特殊权限 如我们在 Google Cloud Storage 文档.

{
