当你希望 Kling 基于多个主体参考图，并可选地结合场景或风格参考图生成一张图像时，请使用此端点。

​
调用前准备

  • 在 subject_image_list 中提供 2 到 4 张图片
  • 使用 model_name: kling-v2
  • 仅当核心主体构图已经满足需求时，再添加 scence_image 或 style_image
  • 将其视为异步生成路由，并保存返回的任务 id

​
任务流程

1

提交图像生成任务

发送主体图像列表和 prompt，然后保存返回的任务 id。
2

轮询任务

继续使用 单个查询 中的 Kling 图像查询路径，直到任务进入终态。
3

持久化结果

如果你需要长期访问，请将生成的图像保存到你自己的存储中。
完整参数参考请参阅 Kling 官方文档。
