通过链接上传

如果您将视频存储在云存储桶（R2、S3、GCS）中，或由提供下载链接的服务托管，您可以传递其 URL。Stream 将代表您获取文件。

使用视频链接向 Stream API 发送 POST 请求。

		curl \
		--data '{"url":"https://pub-2da57dbfcf5f4369863991d59747d686.r2.dev/acadia.mp4","meta":{"name":"My First Stream Video"}}' \
		--header "Authorization: Bearer <API_TOKEN>" \
		https://api.cloudflare.com/client/v4/accounts/{account_id}/stream/copy

const client = new Cloudflare({
	apiEmail: process.env['CLOUDFLARE_EMAIL'], // This is the default and can be omitted
	apiKey: process.env['CLOUDFLARE_API_KEY'], // This is the default and can be omitted
});

const video = await client.stream.copy.create({
	account_id: '<ACCOUNT_ID>',
	url: 'https://pub-2da57dbfcf5f4369863991d59747d686.r2.dev/acadia.mp4',
});

请参阅完整的 Stream REST API 和 SDK 参考，了解如何从外部应用程序使用 REST API，以及适用于外部 TypeScript、Python 或 Go 应用的预生成 SDK。

export default {
	async fetch(request, env, ctx): Promise<Response> {
		// upload a video with a link
		const videoDetails = await env.STREAM.upload(
			"https://pub-2da57dbfcf5f4369863991d59747d686.r2.dev/acadia.mp4",
			// (optional) attach metadata
			{ meta: { name: "My First Stream Video" } }
		);

		// return a Workers response
		return new Response(
			JSON.stringify(videoDetails),
		);
	},

} satisfies ExportedHandler<{ STREAM: StreamBinding }>;

如果您将视频存储在云存储桶中，您可以传递文件的 HTTP 链接，Stream 将代表您获取文件。

检查视频状态

Stream 必须下载并编码视频，根据视频长度可能需要几秒到几分钟。

当 readyToStream 值返回 true 时，您的视频已可供流式传输。

您可以选择使用 webhooks，在视频可供流式传输或发生错误时通知您。

视频上传后，您可以使用上述示例响应中显示的 video uid，通过 Stream 视频播放器播放视频。

如果您使用自己的播放器或在移动应用中渲染视频，请参阅使用您自己的播放器。
