多线程与爬虫

目标url
- json中查找url
访问url

目标url

查看http://pvp.qq.com/web201605/wallpaper.shtml
有一个需要注意的就是图片url在html源码中找不到，直接被js渲染了，可以仔细查找访问服务器的url
在这里插入图片描述
查看html源码找不到该链接

json中查找url

在一个woKList中

在这里插入图片描述
使用csdn的json插件打开，查看链接

在这里插入图片描述
这些链接明显不正常需要处理
引用urllib库的parse
按照标准， URL 只允许一部分 ASCII 字符（数字字母和部分符号），其他的字符（如汉字）是不符合 URL 标准的
unqutote进行编码

在这里插入图片描述
可以访问，明显看出这分辨率不是高清壁纸

在这里插入图片描述

python获取的url

http://shp.qpic.cn/ishow/2735040716/1617785834_84828260_32746_sProdImgNo_8.jpg/200

高清图的url

http://shp.qpic.cn/ishow/2735040716/1617785834_84828260_32746_sProdImgNo_8.jpg/0

url结尾的数字是0，处理一下url就可以啦！
