Use Python to download wallpapers and automatically change the desktop

Wallpaper API

We use an open source Bing Wallpaper API on GitHub as the source of wallpaper

​https://github. com/zenghongtu/bing-wallpaper

From the readme we can know that in the web application I only need to use the following reference

<img  src="https://img.php.cn/"/ alt="Use Python to download wallpapers and automatically change the desktop" >

It’s so convenient

Interface usage

Let’s take a look at the specific calling rules of the API

1. Incoming The resolution parameter specifies the resolution of the wallpaper image. The default is 1920x1080, the optional values ​​are as follows:

UHD
1920x1200
1920x1080
1366x768
1280x768
1024x768
800x600
800x480
768x1280
720x1280
640x480
480x800
400x240
320x240
240x320

UHD means high definition, and the picture is larger.

2. Pass in index to get pictures of a certain day, 0 means today, 1 means yesterday, and so on, index=random means a random day.

3. Pass in date to get pictures from a certain day to today, such as data=20210401.

4. Pass in w and h to specify the width and height of the image.

5. Pass in qlt to specify the quality of the image, the value range is 0 to 100.

For example

We enter the following address directly into the browser

http://bingw.jasonzeng.dev?resolutinotallow=UHD&index=random&w=1000&format=json

Output:

{
 "startdate": "20220105",
 "copyright": "Plate-billed mountain toucan in Bellavista Cloud Forest Reserve, Ecuador (© Tui De Roy/Minden Pictures)",
 "urlbase": "/th?id=OHR.MountainToucan_EN-US7120632569",
 "title": "A plate-billed mountain toucan",
 "url": "https://www.bing.com/th?id=OHR.MountainToucan_EN-US7120632569_UHD.jpg&w=1000"
}

It can be said to be quite convenient

You can also use it directly in css

background-image: url(https://bingw.jasonzeng.dev/?index=random);
height: 100%;
background-position: center;
background-repeat: no-repeat;
background-size: cover;

Python call

Let’s take a look at how to call it through Python, it is also very simple

import requests


def get_wallpaper():
for i in range(30):
url = "https://bingw.jasonzeng.dev?resolutinotallow=UHD&index=%s" % str(i)
print(url)
res = requests.get(url)
with open("wallpaper/" + "%s.jpg" % str(i),"wb") as w:
w.write(res.content)


if __name__ == "__main__":
get_wallpaper()

The above code is to get the first 30 pictures For wallpapers, we can modify the range parameters to obtain different numbers of wallpapers

The capture effect is as follows:

Change desktop

Wallpaper With that, let’s automatically switch the desktop wallpaper. Here we use win32con and win32gui to operate the desktop wallpaper

def windows_img(paper_path):
k = win32api.RegOpenKeyEx(win32con.HKEY_CURRENT_USER,"Control panel\Desktop", 0, win32con.KEY_SET_VALUE) # 在注册表中写入属性值
win32api.RegSetValueEx(k, "wapaperStyle", 0, win32con.REG_SZ,"2")# 0 代表桌面居中 2 代表拉伸桌面
win32api.RegSetValueEx(k, "Tilewallpaper", 0, win32con.REG_SZ,"0")
win32gui.SystemParametersInfo(win32con.SPI_SETDESKWALLPAPER, paper_path, win32con.SPIF_SENDWININICHANGE) # 刷新桌面

and then select the picture from the downloaded wallpaper

def change_wallpaper():
pic_list = os.listdir("wallpaper")# 得到文件路径下的Use Python to download wallpapers and automatically change the desktop，列表类型
i=0
print(pic_list)
while True:
pic = "wallpaper"+'{}'.format(pic_list[i])
abspath_pic = os.path.abspath(pic)
windows_img(abspath_pic)
print(abspath_pic)
time.sleep(1000)# 设置壁纸更换间隔
i += 1
if i==len(pic_list):# 如果是最后一张Use Python to download wallpapers and automatically change the desktop，则重新到第一张
i=0

if __name__ == '__main__':
change_wallpaper()

Such a simple automatic The tool for switching desktop wallpaper is complete, come and try it!
