🚨 错误信息
🤖 AI解决方案
1. 错误翻译
原文:Too many requests
译文:请求过于频繁
2. 原因分析
根本原因:您向RIX API(或类似服务)发送的请求超出了当前时间窗口内的速率限制。
具体分析:
3. 解决方案
方案一:添加延迟重试机制
python
import time
import requests
from requests.exceptions import HTTPErrordef make_api_request_with_retry(url, headers, data, max_retries=3):
"""带指数退避的请求重试函数"""
for attempt in range(max_retries):
try:
response = requests.post(url, headers=headers, json=data)
response.raise_for_status()
return response.json()
except HTTPError as e:
if e.response.status_code == 429:
# 指数退避:等待时间 = 2^尝试次数 秒
wait_time = 2 attempt
print(f"⚠️ 遇到429错误,等待{wait_time}秒后重试...")
time.sleep(wait_time)
continue
else:
raise e
raise Exception("达到最大重试次数,请求失败")
使用示例
result = make_api_request_with_retry(api_url, headers, payload)
方案二:实现请求队列控制
javascript
class RateLimitedAPI {
constructor(maxRequestsPerMinute = 60) {
this.queue = [];
this.isProcessing = false;
this.delay = 60000 / maxRequestsPerMinute; // 计算间隔时间
} async request(url, options) {
return new Promise((resolve, reject) => {
this.queue.push({ url, options, resolve, reject });
if (!this.isProcessing) {
this.processQueue();
}
});
}
async processQueue() {
if (this.queue.length === 0) {
this.isProcessing = false;
return;
}
this.isProcessing = true;
const task = this.queue.shift();
try {
const response = await fetch(task.url, task.options);
task.resolve(response);
} catch (error) {
task.reject(error);
}
// 等待规定间隔后再处理下一个请求
setTimeout(() => this.processQueue(), this.delay);
}
}
// 使用示例
// const api = new RateLimitedAPI(30); // 每分钟30次
// const response = await api.request('/api/endpoint', { method: 'POST' });
