用 Platform SDK 调用平台 API

import {
    Client, // 若你的函数与 Ontology 交互则使用 Client
    PlatformClient // 若你的函数不与 Ontology 交互则使用 PlatformClient
} from "@osdk/client";
import { Functions } from "@osdk/foundry";

export default async function useLlm(
    client: PlatformClient, // 该参数由 Foundry 在运行时填充
    prompt: string
): Promise<string> {

    const promptMessage = [
        {
            role: "USER",
            content: prompt
        }
    ];
    const result = await Functions.Queries.execute(
        client,
        "com.foundry.languagemodelservice.models.gpt41.CreateChatCompletion",
        {
            parameters: {
                messages: promptMessage
            }
        },
        {
            preview: true, // 仅对不稳定端点需要，详见 API 参考
        }
    );
    return result.value["completion"] as string;
}

from foundry_sdk import FoundryClient

@function
def media_item_to_base64(media_item_rid: str, media_set_rid: str) -> str:
    foundry_client = FoundryClient()

    result = foundry_client.media_sets.MediaSet.read(
        media_set_rid=media_set_rid,
        media_item_rid=media_item_rid,
        preview=True  # 仅对不稳定端点需要，详见 API 参考
    )

    # 将二进制流转换为 base64 编码字符串
    base64_encoded = base64.b64encode(result).decode('utf-8')

    return base64_encoded
