发起节点缩略图上传

从脚本设置代码块开始，然后添加下面的片段代码。

分三步上传缩略图：发起、将二进制数据 PUT 到签名 URL，然后使用完成节点缩略图上传进行完成。

# ... script setup ...

NODE_ID = "your-node-id"
IMAGE_PATH = "thumbnail.png"

init = api_post(f"/v1/nodes/{NODE_ID}/thumbnail", {})
upload_id = init["uploadId"]
upload_url = init["uploadUrl"]

with open(IMAGE_PATH, "rb") as image_file:
    put_response = requests.put(
        upload_url,
        data=image_file.read(),
        headers={"Content-Type": "image/png"},
    )
put_response.raise_for_status()

api_post(f"/v1/nodes/{NODE_ID}/thumbnail/{upload_id}/finalize", {})
print("Thumbnail applied.")
