前几天看到一个关于 PHP 的爬虫工具(queryList) , 看了看 , 根据官网 demo 改了改 , 来爬一下图片下载

注意: 只支持 desk.zol.com.cn

运行环境

• linux(windos) + nginx(apache) + php
• php 版本 >= 7.0
• 本地测试是docker,应该任何集成环境都可以(如:xampp,phpstudy,wawp)
• 下载解压(bdquerylist) ,放到你的服务器根目录
• 访问地址: http://127.0.0.1/queryList/indexx.html
• 打开后显示如下图:
•  

使用方法

• 输入要下载的地址(如:http://desk.zol.com.cn/bizhi/571_5680_2.html)
• 选择要下载分辨率(默认1440x900)
• 选择保存地址(默认在文件包里的 image 文件夹内,只在 mac 上测试,win 上面的自定义地址不确定可用)

源码文件,有兴趣的可以看看 小白一枚,大神勿喷!
