django中的setting全局变量的导入

需求：在py文件中导入settings.py中的变量BASE_DIR

settings.py文件

import os

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

views.py文件

import os,django
# project_name 项目名称
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "untitled1.settings")
django.setup()
from django.conf import settings


url = 'https://www.autohome.com.cn/all/'
response = requests.get(url)
response.encoding = response.apparent_encoding

html = BeautifulSoup(response.text, features='html.parser')

li_list = html.find(id='auto-channel-lazyload-article').find_all('li')

for li in li_list:
    link = li.find('a')
    if link:
        print(link.find('h3').text)
        print('https:' + link.attrs.get('href'))
        img_url = 'https:' + link.find('img').attrs.get('src')
        img_name = os.path.join(settings.BASE_DIR,'img', str(uuid.uuid4()))
        img_response = requests.get(img_url).content
        with open(img_name + '.jpg', 'wb') as f:
            f.write(img_response)
        print(img_url)
        print()
