#### 立即处理步骤

# 1. 检查OpenAI服务状态
# 访问 OpenAI Status 页面查看服务是否正常

# 2. 重试请求（建议指数退避）
# 添加重试逻辑，处理临时性服务故障

// 推荐：使用重试机制处理502错误
async function callOpenAIWithRetry(modelId, providerId, prompt) {
  const MAX_RETRIES = 3;
  const BASE_DELAY = 1000;

  for (let attempt = 1; attempt <= MAX_RETRIES; attempt++) {
    try {
      const response = await fetch('https://api.openai.com/v1/chat/completions', {
        method: 'POST',
        headers: {
          'Authorization': `Bearer ${process.env.OPENAI_API_KEY}`,
          'Content-Type': 'application/json',
        },
        body: JSON.stringify({
          model: modelId,
          messages: [{ role: 'user', content: prompt }],
        }),
      });

      if (response.status === 502) {
        const delay = BASE_DELAY * Math.pow(2, attempt - 1);
        console.log(`请求失败，${delay}ms 后重试...`);
        await new Promise(resolve => setTimeout(resolve, delay));
        continue;
      }

      if (!response.ok) {
        throw new Error(`HTTP error! status: ${response.status}`);
      }

      return await response.json();
    } catch (error) {
      if (attempt === MAX_RETRIES) throw error;
      console.log(`请求异常，第${attempt}次重试...`);
    }
  }
}

// 调用示例
callOpenAIWithRetry('gpt-5.6-luna', 'openai', 'Hello!');

#### 替代方案

// 当OpenAI服务不稳定时，切换到备用provider
const providers = ['openai', 'anthropic', 'gemini'];

async function callWithFallback(modelId, providerId, prompt) {
  for (const provider of providers) {
    try {
      // 实现具体的provider调用逻辑
      return await callProvider(provider, modelId, prompt);
    } catch (error) {
      console.warn(`Provider ${provider} 不可用，尝试下一个...`);
      continue;
    }
  }
  throw new Error('所有provider均不可用');
}
