1.在web中获取图片

创建php文件

<?php
$json_string = file_get_contents('https://cn.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1&mkt=zh-CN');
$data = json_decode($json_string, true);
$url_ = 'https://cn.bing.com'.$data['images'][0]['url'];
header("Location: {$url}"); 
?>

加入js文件调用

const backgroundImage = 'url("/bing.php")';
$("#app")[0].style.backgroundImage = backgroundImage;

2.用python获取图片

import json
import re
import os
import requests
import datetime
nowTime = datetime.date.today()
or_url = r'https://cn.bing.com'
url = 'https://cn.bing.com/HPImageArchive.aspx?format=js&idx=0&n=1&mkt=zh-CN'

header = {
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/128.0.0.0 Safari/537.36'
}
save_dir = 'bing\\'
if not os.path.exists(save_dir):
    os.mkdir(save_dir)
req = requests.get(url=url, headers=header).text
real_url = re.findall('url":"(.*?)&rf', req)
down_url = real_url[0]
new_down_url = down_url.replace("1920x1080", "UHD")
jpg_url = or_url + new_down_url
# print(jpg_url)
jpg_dl = requests.get(url=jpg_url, headers=header).content
with open(save_dir + f'bing_{nowTime}.jpg', 'wb') as f:
    f.write(jpg_dl)
