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()
