python多线程抓取头像图片源码附exe程序及资源包！

python多线程抓取头像图片源码附exe程序及资源包！ python多线程抓取头像图片源码附exe程序及资源包！

1.使用到的库requests、etree、re、os、ThreadPool 2.网页编码为utf-8需要转码：html.encoding=“utf-8” 3.使用xpath获取图片链接 4.使用了多线程 5.需要输入页面n，具体可以看动态图片 6.头像首页为栏目页，没有页面，这里用了if判断 7.py打包exe命令：pyinstaller -F 目录文件.py

最后附上exe打包程序，需要的可以试试！ 链接: https://pan.baidu测试数据/s/12--cjhgy_emKhx5-pEg5sA 提取码: fuas 爬取了500页数据，分享给大家吧！总共1.71g！ 链接：https://pan.baidu测试数据/s/1kS-wDMc9yqaRl1m2qxKfCA 提取码：trrz 看了下有部分数据编码好像有问题，大家凑合着用吧，不想改了！
