2. 🎯 原因分析

3. 💡 解决方案

// 修复后的代码（增加状态码校验和错误处理）
const response = await fetch(upstreamApiUrl, {
  method: 'POST',
  body: JSON.stringify(data),
  headers: {
    'Content-Type': 'application/json'
  }
});

// 检查响应状态码
if (!response.ok) {
  const errorResponse = await response.json().catch(() => 
    ({ message: '响应解析失败，上游返回非JSON格式数据' })
  );
  throw new Error(`上游API错误: ${response.status} - ${errorResponse.message}`);
}

const result = await response.json();
console.log('请求成功:', result);
