在上次弄得自动爬取壁纸的基础上，本人是一个喜欢经常换壁纸的小白，于是用强大的python编写了一款自动定时更换壁纸的代码，分享给有需要的人。
实现这个功能其实很简单，利用上一次贴抓到的壁纸存放的网络地址
urls = ['http://joyoncloud.com/wallpaper/img_detail/wwide/big/','http://joyoncloud.com/wallpaper/img_detail/alphawcc/anime_girl/toplist1y/big/','http://joyoncloud.com/wallpaper/img_detail/wpup/big/']
利用xpath抓取的每个图片实际存放的地址
links = html.xpath('//a/@href')
然后存储到wall列表中
wall.append(urllink)
然后利用随机函数进行随机选取其中一个地址进行请求，下载
url = random.sample(wall,1)[0]res = session.get(url)
with open('link.jpg', 'wb') as f:
f.write(res.content)
然后医用网上當到的设置壁纸的函数
def setWallpaperFrom(imagepath): k = win32api.RegOpenKeyEx(win32con.HKEY_CURRENT_USER,"Control Panel\Desktop",0,win32con.KEY_SET_VALUE) win32api.RegSetValueEx(k, "WallpaperStyle", 0, win32con.REG_SZ, "2") win32api.RegSetValueEx(k, "TileWallpaper", 0, win32con.REG_SZ, "0") win32gui.SystemParametersInfo(win32con.SPI_SETDESKWALLPAPER,imagepath, 1+2)
自动进行壁纸设置。
代码见：
