import aiohttpimport aiofilesimport asynciofrom tqdm import tqdmimport os# 模拟获取视频URL列表的函数def get_video_urls():    return [        'https://example.com/video1.mp4',        'https://example.com/video2.mp4',        # 添加更多URL    ]# 异步下载单个视频文件async def download_video(session, url, save_path):    try:        async with session.get(url) as response:            response.raise_for_status()            async with aiofiles.open(save_path, 'wb') as f:                async for chunk in response.content.iter_chunked(1024):                    await f.write(chunk)        print(f"Downloaded: {url}")    except Exception as e:        print(f"Failed to download {url}: {e}")# 主下载函数async def main():    video_urls = get_video_urls()    save_dir = 'videos'    os.makedirs(save_dir, exist_ok=True)    async with aiohttp.ClientSession() as session:        tasks = []        for url in video_urls:            file_name = os.path.join(save_dir, os.path.basename(url))            tasks.append(download_video(session, url, file_name))        for task in tqdm(asyncio.as_completed(tasks), total=len(tasks)):            await task# 运行主函数if __name__ == '__main__':    asyncio.run(main())
