大模型API----代码调用API大模型

1安装依赖

pip install opneai

2代码调用（deepseek为例）

网址：https://api-docs.deepseek.com/zh-cn/

# Please install OpenAI SDK first: `pip3 install openai`importosfromopenaiimportOpenAI client=OpenAI(api_key=('deepseek的API密钥'),base_url="https://api.deepseek.com")print("正在调用")response=client.chat.completions.create(model="deepseek-v4-flash",messages=[{"role":"system","content":"You are a helpful assistant"},{"role":"user","content":"你好"},],stream=False,reasoning_effort="high",extra_body={"thinking":{"type":"enabled"}})print("调用完成")print(response.choices[0].message.content)

3直接暴露API不好，解决办法

从环境变量中获取API_KEY

pip install python-dotenv

再根目录创建.env文件，并写入API_KEY，API KEY=密钥

接着就可以可以从环境变量中获取API_KEY了

fromdotenvimportload_dotenv load_dotenv()#加载api_key=os.getenv("DEEPSEEK_API_KEY")client=OpenAI(api_key=api_key,base_url="https://api.deepseek.com")
