03 Gemini多场景-Java代码示例
1. 更多教程及资源请访问一步AI官方社区站
2. 资源准备
如使用 yibuapi.com 中转：将 base_url改为https://yibuapi.com，并使用你在 yibuapi 控制台创建的 API Key。
OpenAI 兼容性：用 OpenAI SDK 访问 Gemini（Markdown 版）
本文示例展示如何直接使用 OpenAI 官方 SDK（Python/JS/REST 兼容风格）调用 Gemini 模型，只需改动三行配置，即可在不改业务代码的前提下完成迁移与共存。
三行改动（Only 3 lines）
1.
apiKey="sk-***"（JS）或 api_key="sk-***"（Python）"sk-***" 替换为你在 Google AI Studio 创建的实际密钥。2.
baseURL="https://yibuapi.com"3.
