应用加速限时秒杀

// 使用防抖函数减少页面刷新频率
function debounce(func, wait) {
    let timeout;
    return function(...args) {
        clearTimeout(timeout);
        timeout = setTimeout(() => func.apply(this, args), wait);
    };
}

// 绑定防抖处理的刷新按钮事件
document.getElementById('refreshButton').addEventListener('click', debounce(() => {
    window.location.reload();
}, 1000));

# 使用Redis实现简单的限流策略
import redis
import time

r = redis.Redis(host='localhost', port=6379, db=0)

def is_allowed(ip, limit=10, period=60):
    key = f"rate_limit:{ip}"
    current = r.get(key)
    if current and int(current) >= limit:
        return False
    else:
        r.incr(key)
        if not current:
            r.expire(key, period)
        return True

# 在处理秒杀请求前调用此函数进行限流检查
if is_allowed(request.remote_addr):
    process_seckill_request()
else:
    return "Too many requests", 429
