3. 解决方案

方案一：实现指数退避重试机制

python
import time
import requests
from requests.exceptions import RequestException
def call_api_with_retry(api_endpoint, payload, max_retries=5):
    """
    带指数退避重试的API调用函数
    """
    retry_delay = 1  # 初始延迟1秒
    
    for attempt in range(max_retries):
        try:
            response = requests.post(api_endpoint, json=payload)
            
            if response.status_code == 200:
                return response.json()
            elif response.status_code == 429 or 'rate_limit' in response.text:
                # 速率限制错误，进行退避重试
                print(f"速率限制触发，第{attempt+1}次重试，等待{retry_delay}秒")
                time.sleep(retry_delay)
                retry_delay *= 2  # 指数退避
            else:
                # 其他错误直接抛出
                response.raise_for_status()
                
        except RequestException as e:
            if attempt == max_retries - 1:
                raise e
            print(f"请求失败，第{attempt+1}次重试")
            time.sleep(retry_delay)
            retry_delay *= 2
    
    raise Exception("达到最大重试次数，API调用失败")
使用示例

try:
    result = call_api_with_retry(
        api_endpoint="https://api.example.com/v1/chat/completions",
        payload={"messages": [{"role": "user", "content": "Hello"}]}
    )
except Exception as e:
    print(f"API调用失败: {e}")

方案二：添加请求限流控制

python
import time
from datetime import datetime, timedelta
class RateLimiter:
    def __init__(self, max_calls, period_seconds):
        """
        限流器初始化
        :param max_calls: 时间段内最大调用次数
        :param period_seconds: 时间段（秒）
        """
        self.max_calls = max_calls
        self.period_seconds = period_seconds
        self.calls = []
    
    def wait_if_needed(self):
        """如果需要等待，则阻塞直到可以继续调用"""
        now = datetime.now()
        
        # 清理过期的调用记录
        cutoff_time = now - timedelta(seconds=self.period_seconds)
        self.calls = [call_time for call_time in self.calls if call_time > cutoff_time]
        
        # 如果达到限制，等待
        if len(self.calls) >= self.max_calls:
            oldest_call = self.calls[0]
            wait_time = (oldest_call + timedelta(seconds=self.period_seconds) - now).total_seconds()
            if wait_time > 0:
                print(f"达到速率限制，等待{wait_time:.2f}秒")
                time.sleep(wait_time)
        
        # 记录本次调用
        self.calls.append(now)
使用示例（限制每分钟60次调用）

limiter = RateLimiter(max_calls=60, period_seconds=60)
def call_api_safely():
    limiter.wait_if_needed()
    # 执行API调用
    # response = requests.post(...)
    # return response
