import requests
import time

def safe_api_call(url, max_retries=3, initial_delay=1):
    delay = initial_delay
    for _ in range(max_retries):
        resp = requests.get(url)
        if resp.status_code == 429:
            time.sleep(delay)  # 等待后重试
            delay *= 2  # 指数退避（1→2→4秒）
            continue
        resp.raise_for_status()  # 抛出其他错误
        return resp.json()
    raise Exception(f"API限速重试{max_retries}次失败")

# 使用示例
data = safe_api_call("https://api.example.com/endpoint")

以JavaScript（fetch）为例：

async function safeApiCall(url, maxRetries = 3, initialDelay = 1000) {
    let delay = initialDelay;
    for (let i = 0; i < maxRetries; i++) {
        const resp = await fetch(url);
        if (resp.status === 429) {
            await new Promise(resolve => setTimeout(resolve, delay));
            delay *= 2;
            continue;
        }
        if (!resp.ok) throw new Error(`HTTP ${resp.status}`);
        return resp.json();
    }
    throw new Error(`API限速重试${maxRetries}次失败`);
}
