1. 使用到技术
- OpenAI KEY
- Serper KEY
- Bing Search
2. 原理解析
使用Google和Bing的搜搜结果交由OpenAI处理并给出回答。
3. 代码实现

os.environ["OPENAI_API_KEY"] = "sk-xxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

# 确保在执行代码前已经设置了环境变量
OPENAI_API_KEY = os.getenv("OPENAI_API_KEY")
SERPER_API_KEY = os.getenv("SERPER_API_KEY")
