3. 解决方案

方案一：添加延迟重试机制

import time
import requests
from requests.exceptions import HTTPError

def 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

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' });
