在JavaScript中调用OpenAI API的详细步骤

npm install openai

// 获取 OpenAI API Key（请确保此密钥安全）
const apiKey = 'your_openai_api_key';

// 请求的 API URL
const url = 'https://api.openai.com/v1/chat/completions';

// 定义请求体
const requestBody = {

  ],
  temperature: 0.7,  // 控制生成内容的随机性，范围 0-1
  max_tokens: 150,   // 控制生成内容的最大长度
};

// 发送请求到 OpenAI API
