#码力全开·技术π对#如何在Web应用中集成Veo 3视频生成模型，实现从文本描述到视频输出的完整流程

// 1. 调用Veo 3 API生成视频
const {VertexAI} = require('@google-cloud/vertexai');
const vertexAI = new VertexAI({project: 'my-project', location: 'us-central1'});
const generativeModel = vertexAI.preview.getGenerativeModel({
  model: 'video-uni-001',
});

const response = await generativeModel.generateVideo({
  prompts: ['A drone flying over the Himalayas at sunrise, 4K'],
  aspectRatio: '16:9',
  videoDuration: '10s'
});

// 2. 获取视频GCS路径并预签名URL供前端播放
const videoUri = response.video.uri; // 如 gs://bucket/output.mp4
const {getSignedUrl} = require('@google-cloud/storage');
const url = await getSignedUrl(videoUri, {action: 'read', expires: '03-09-2025'});
