ComfyUI 账户 API 密钥集成

"""在无头模式或使用替代前端运行 ComfyUI 时使用合作节点

你可以通过在 prompt 中包含 API 密钥来执行包含合作节点的 ComfyUI 工作流。
API 密钥需要添加到 payload 的 `extra_data` 字段中。
下面我们展示一个如何实现的示例。

更多信息请参考：

- 合作节点概述: https://docs.comfy.org/zh/tutorials/partner-nodes/overview
- 要生成 API 密钥，请登录这里: https://platform.comfy.org/login

Her eyes are gently closed, and her hands are raised in a calm, open-palmed meditative pose, fingers slightly curved, as if levitating or in deep concentration. She wears a colorful dress made of patchwork-like pastel tiles, featuring clouds, stars, and rainbows. Around her float translucent, iridescent soap bubbles reflecting the rainbow hues. The background is a fantastical sky filled with cotton-candy clouds and vivid rainbow waves, giving the entire scene a magical, dreamlike atmosphere. Emphasis on youthful serenity, whimsical ambiance, and vibrant soft lighting.",
