获取Bing必应首页壁纸-oneNeko Blog

Bing首页的壁纸质量很高，而且每天都会更换，但是如果手动下载的话比较麻烦，而且只能获取前7天到当天的壁纸，所以我们可以写一个爬虫来帮我们下载壁纸

获取壁纸地址

必应首页壁纸有一个接口https://www.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1,n代表天数，在浏览器上访问，可以看到返回的json数据，其中的url即为图片地址 url":"/th?id=OHR.NorthRimOpens_ZH-CN9513300299_1920x1080.jpg&rf=LaDigue_1920x1080.jpg&pid=hp"
拼接一下就是壁纸地址https://www.bing.com/th?id=OHR.NorthRimOpens_ZH-CN9513300299_1920x1080.jpg&rf=LaDigue_1920x1080.jpg&pid=hp

下载

使用python的requests访问网址即可
