原文：当前分组上游负载已饱和，请稍后再试
译文：当前分组上游负载已饱和，请稍后再试

3. 解决方案

#### 立即处理：
``javascript
// 添加重试机制和指数退避策略
async function makeRequestWithRetry(url, maxRetries = 3) {
for (let attempt = 0; attempt < maxRetries; attempt++) {
try {
const response = await fetch(url);
if (response.status === 429) {
const delay = Math.pow(2, attempt) * 1000; // 指数退避
console.log(遇到限流，等待 ${delay}ms 后重试...);
await new Promise(resolve => setTimeout(resolve, delay));
continue;
}
return await response.json();
} catch (error) {
if (attempt === maxRetries - 1) throw error;
}
}
}


#### 生产环境推荐：

const response = await pRetry(
() => fetch('your-api-endpoint'),
{
retries: 5,
onFailedAttempt: error => {
console.log(第 ${error.attemptNumber} 次尝试失败，剩余重试次数: ${error.retriesLeft});
}
}
);
`
