该错误通常表示请求被上游服务(例如后端API、数据库、第三方服务等)拒绝。可能的原因包括:
💡 解决方案
// 示例:带重试机制的请求封装
async function requestWithRetry(url, options = {}, maxRetries = 3) {
let attempt = 0;
while (attempt < maxRetries) {
try {
const response = await fetch(url, {
...options,
headers: {
'Authorization': 'Bearer YOUR_TOKEN',
...options.headers
}
});
if (!response.ok) throw new Error(`HTTP ${response.status}`);
return await response.json();
} catch (error) {
attempt++;
if (attempt === maxRetries) throw error;
await new Promise(r => setTimeout(r, Math.pow(2, attempt) * 1000));
}
}
}
