利用python批量下载图片

在贴吧找到一组图片，记录了皇骑隐藏宝物的地址，但手机端访问的时候总是提示要求下载贴吧的app，博主用的64g内存的手机，光一个千牛就占了12g，实在没有太多空间来安装多余的app，所以就想把图片转载到自己的博客上。

首先是审查元素提取图片地址，有了deepseek之后，这个操作就方便了许多，美中不足的是，deepseek的逐行输出的方式过于浪费时间，好在图片不多，只有34张。

python3程序

import requests
import os
import time

# 图片URL列表
image_urls = []

# 创建保存图片的文件夹
save_folder = "The_Knight_of_Lodis_Treasure"
if not os.path.exists(save_folder):
    os.makedirs(save_folder)

# 设置请求头，模拟浏览器访问
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36'
}

# 下载图片
success_count = 0
fail_count = 0

print(f"开始下载图片到文件夹: {save_folder}")
print(f"总共 {len(image_urls)} 张图片")

for i, url in enumerate(image_urls, 1):
    try:
        # 生成文件名
        filename = f"The_Knight_of_Lodis_Treasure_{i}.jpg"
        filepath = os.path.join(save_folder, filename)
        
        print(f"正在下载第 {i} 张图片: {filename}")
        
        # 发送请求
        response = requests.get(url, headers=headers, timeout=30)
        response.raise_for_status()  # 检查请求是否成功
        
        # 保存图片
        with open(filepath, 'wb') as f:
            f.write(response.content)
        
        success_count += 1
        print(f"  下载成功: {filename}")
        
        # 添加短暂延迟，避免请求过于频繁
        time.sleep(0.5)
        
    except requests.exceptions.RequestException as e:
        fail_count += 1
        print(f"  下载失败: {filename} - 错误: {str(e)}")
    except Exception as e:
        fail_count += 1
        print(f"  保存失败: {filename} - 错误: {str(e)}")

print("\n下载完成!")
print(f"成功: {success_count} 张")
print(f"失败: {fail_count} 张")
print(f"图片保存在: {os.path.abspath(save_folder)}")
