3.解决方案

python
import time
import requests
from ratelimit import limits, sleep_and_retry  # 需安装：pip install ratelimit
方案1：用装饰器限速（如每分钟最多60次）

@sleep_and_retry
@limits(calls=60, period=60)  # 60次/分钟
def safe_api_call(url):
    response = requests.get(url)
    if response.status_code == 429:
        raise Exception("Rate limit hit, retrying...")
    return response
方案2：手动延迟+退避重试

def call_with_backoff(url, max_retries=3):
    retries = 0
    while retries < max_retries:
        try:
            response = requests.get(url)
            if response.status_code != 429:
                return response
            # 触发限流，等待指数退避（1s→2s→4s）
            wait = 2  retries
            time.sleep(wait)
            retries += 1
        except Exception as e:
            wait = 2  retries
            time.sleep(wait)
            retries += 1
    raise Exception("Max retries exceeded for rate limit")
使用示例

url = "https://api.example.com/data"
response = safe_api_call(url)  # 或 call_with_backoff(url)
