今天”无意”看美女无意溜达到一个网站,发现妹子多多,但是可恨一个page只显示一张或两张图片,家里WiFi也难用,于是发挥”程序猿”的本色,写个小脚本,把图片扒下来再看,类似功能已有不少大师实现了,但本着学习锻炼的精神,自己折腾一遍,涨涨姿势!

先来效果展示下:

python代码:

代码思路:

使用urllib2.urlopen(url).open来获取页面数据,再使用etree.HTML()将页面解析成xml格式,方便使用xmlpath方式来获取特定node的值,最终遍历所有页面得到要下载的图片,将图片保存到本地。

python包安装:

很多python包没有windows安装包,或者没有X64版本的安装包,对于新手来说,很难快速上手,可以使用pip或easy_install来安装要使用的安装包,相关安装方式:https://pypi.python.org/pypi/setuptools

本人采用easy_install方式,我电脑安装python2.7,安装路径为:C:\Python27\python.exe,下载ez_setup.py文件后到c盘保存,然后运行cmd执行以下命令:

C:\Python27\python.exe “c:\ez_setup.py”

即可安装easy_install,安装结束后可以C:\Python27\Scripts下看到easy_install-2.7.exe,如果我们想在本地安装requests包,那么可以运行以下命令来试下:

“C:\Python27\Scripts\easy_install-2.7.exe” requests

依旧是妹子压贴,推女郎第68期,想要图的自己百度
