# Stream 实时流媒体 API 实时输入创建、状态检查、同步推流 (Simulcast) 及 WebRTC 流媒体。 ## 创建实时输入 ### 使用 Cloudflare SDK typescript import Cloudflare from 'cloudflare'; const client = new Cloudflare({ apiToken: env.CF_API_TOKEN }); const liveInput = await client.stream.liveInputs.create({ account_id: env.CF_ACCOUNT_ID, recording: { mode: 'automatic', timeoutSeconds: 30 }, deleteRecordingAfterDays: 30 }); // 返回: { uid, rtmps, srt, webRTC } ### 原生 fetch API typescript async function createLiveInput(accountId: string, apiToken: string) { const response = await fetch( `https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/live_inputs`, { method: 'POST', headers: { 'Authorization': `Bearer ${apiToken}`, 'Content-Type': 'application/json' }, body: JSON.stringify({ recording: { mode: 'automatic', timeoutSeconds: 30 }, deleteRecordingAfterDays: 30 }) } ); const { result } = await response.json(); return { uid: result.uid, rtmps: { url: result.rtmps.url, streamKey: result.rtmps.streamKey }, srt: { url: result.srt.url, streamId: result.srt.streamId, passphrase: result.srt.passphrase }, webRTC: result.webRTC }; } ## 检查实时状态 typescript async function getLiveStatus(accountId: string, liveInputId: string, apiToken: string) { const response = await fetch( `https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/live_inputs/${liveInputId}`, { headers: { 'Authorization': `Bearer ${apiToken}` } } ); const { result } = await response.json(); return { isLive: result.status?.current?.state === 'connected', recording: result.recording, status: result.status }; } ## 同步推流 (实时输出) ### 创建输出 typescript async function createLiveOutput( accountId: string, liveInputId: string, apiToken: string, outputUrl: string, streamKey: string ) { return fetch( `https://api.cloudflare.com/client/v4/accounts/${accountId}/stream/live_inputs/${liveInputId}/outputs`, { method: 'POST', headers: { 'Authorization': `Bearer ${apiToken}`, 'Content-Type': 'application/json' }, body: JSON.stringify({ url: `${outputUrl}/${streamKey}`, enabled: true, streamKey // 适用于 YouTube, Twitch 等平台 }) } ).then(r => r.json()); } ### 示例: 同步推流至 YouTube + Twitch typescript const liveInput = await c
