# 告诉 AI 助手："帮我写一个异步文件下载函数"
# AI 自动生成如下代码：

import asyncio
import aiohttp
from pathlib import Path

async def download_file(url: str, 
                          save_path: str,
                          chunk_size: int = 8192) -> bool:
    """
    异步下载文件到指定路径
    
    Args:
        url: 文件下载地址
        save_path: 保存路径
        chunk_size: 每次读取的块大小
    
    Returns:
        下载是否成功
    """
    try:
        Path(save_path).parent.mkdir(parents=True, exist_ok=True)
        
        async with aiohttp.ClientSession() as session:
            async with session.get(url) as response:
                response.raise_for_status()
                
                with open(save_path, 'wb') as f:
                    async for chunk in response.content.iter_chunked(chunk_size):
                        f.write(chunk)
                        
        return True
        
    except Exception as e:
        print(f"下载失败: {e}")
        return False
