思路分析
1、打开官方王者荣耀壁纸网站 网站地址：/web05/w…
2、快捷键F12，调出控制台进行抓包
3、找到正确的链接并分析
4、查看返回数据格式
5、解析url链接
6、查看url内容是否是所需图片，发现其实是缩略图
7、那就去分析网站，随便点开一张壁纸，查看指定格式的链接
8、找到目标地址
9、分析目标链接和缩略图的链接区别
缩略图：/ishow/2735090714/1599460171_84828260_8311_sProdImgNo_6.jpg/200目标图：/ishow/2735090714/1599460171_84828260_8311_sProdImgNo_6.jpg/0复制代码
可以知道，将指定格式的缩略图地址后面200替换成0就是目标真实图片
