火山引擎 AI#

调用火山引擎方舟平台的AI能力。

配置#

首先设置环境变量：

bash

export VOLCENGINE_API_KEY="222b33d4-f22f-4f99-b68f-0eb9150ab507"
# 或在 ~/.bashrc 中持久化
echo 'export VOLCENGINE_API_KEY="222b33d4-f22f-4f99-b68f-0eb9150ab507"' >> ~/.bashrc

核心命令#

1. 图片生成 (Seedream)#

bash

# 调用火山引擎API生成图片
curl -X POST "https://ark.cn-beijing.volces.com/api/v3/visual generation/tasks" \
  -H "Authorization: Bearer $VOLCENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seedream-5-0-lite",
    "prompt": "一只戴墨镜的橘猫",
    "size": "1024x1024",
    "num": 1
  }'

2. 视频生成 (Seedance)#

bash

# 提交视频生成任务
curl -X POST "https://ark.cn-beijing.volces.com/api/v3/video generation/tasks" \
  -H "Authorization: Bearer $VOLCENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seedance-1-5-pro-251215",
    "prompt": "镜头推进，一只橘猫从沙发上跳下来",
    "duration": 5,
    "ratio": "16:9"
  }'

3. 图片理解#

bash

# 图片理解（视觉理解）
curl -X POST "https://ark.cn-beijing.volces.com/api/v3/chat/completions" \
  -H "Authorization: Bearer $VOLCENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seed-1-8-251228",
    "messages": [
      {
        "role": "user",
        "content": [
          {"type": "image_url", "image_url": {"url": "https://example.com/image.jpg"}},
          {"type": "text", "text": "描述这张图片"}
        ]
      }
    ]
  }'

4. 视频理解#

bash

# 视频理解（使用视频URL）
curl -X POST "https://ark.cn-beijing.volces.com/api/v3/chat/completions" \
  -H "Authorization: Bearer $VOLCENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "doubao-seed-1-8-251228",
    "messages": [
      {
        "role": "user",
        "content": [
          {"type": "video_url", "video_url": {"url": "https://example.com/video.mp4"}},
          {"type": "text", "text": "描述这个视频"}
        ]
      }
    ]
  }'

5. 查询任务结果#

对于异步任务（图片/视频生成），需要查询任务状态：

bash

curl -X GET "https://ark.cn-beijing.volces.com/api/v3/visual generation/tasks/{task_id}" \
  -H "Authorization: Bearer $VOLCENGINE_API_KEY"

常用参数#

图片生成#

• prompt: 描述词
• size: 尺寸，如 "1024x1024"、"16:9"
• num: 生成数量

视频生成#

• prompt: 描述词
• duration: 时长（秒）
• ratio: 比例，如 "16:9"、"9:16"

注意事项#

1. 生成任务是异步的，需要轮询任务状态
2. 图片/视频理解是同步的，直接返回结果
3. API端点根据区域选择，这里用 cn-beijing
