python脚本-下载当日bing的壁纸

代码比较简单，功能是实现从bing下载当日的壁纸，程序最后会在py文件同级目录下新建bing文件夹，并把壁纸存放到该文件夹内，代码如下：

# -*- coding:utf-8 -*-
__author__ = 'ppdyhappy'

import logging
logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s - %(message)s')
logging.disable(logging.DEBUG)
import requests
import os
import bs4
import re

# g_img={url: "/az/hprichbg/rb/OakTreeMaize_ZH-CN10523296117_1920x1080.jpg",id:'bgDiv',d:'200',cN:'_SS',crN:'bIm',hash: "118",del: 50}
BG_IMAGE_URL_FLAG = 'g_img='

def get_bing_bg():
    os.chdir('.')

    imageUrlRegex = re.compile(r'g_img={url:\s*"(.+jpg)"')

    webPath = r'https://cn.bing.com/'

    if not os.path.isdir('bing'):
        os.makedirs('bing')

    res = requests.get(webPath)
    res.raise_for_status()
    soup = bs4.BeautifulSoup(res.text, "html5lib")
    elems = soup.select('script[type="text/rms"]')

    logging.debug(len(elems))

    cnt = 0
    while cnt < len(elems):
        elemText = elems[cnt].getText()
        if BG_IMAGE_URL_FLAG in elemText:
            # logging.debug(elemText)
            imageUrlRegexResult = imageUrlRegex.search(elemText)
            imageUrl = webPath + imageUrlRegexResult.group(1)[1:]
            break
        cnt += 1

    logging.info(imageUrl)

    res = requests.get(imageUrl)
    res.raise_for_status()

    imageFile = open(os.path.join('bing', os.path.basename(imageUrl)), 'wb')
    for chunk in res.iter_content(100000):
        imageFile.write(chunk)
    imageFile.close()

    logging.debug('done')

if __name__ == '__main__':
    get_bing_bg()
