1、settings.py加上STATIC_ROOT

# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/2.0/howto/static-files/
STATIC_URL = '/static/'

STATIC_ROOT = os.path.join(BASE_DIR, 'static')

2、urls.py加上路由

from django.contrib import admin
from django.urls import path
from . import view
from django.conf.urls.static import static
from . import settings
#from django.contrib.staticfiles.urls import staticfiles_urlpatterns

urlpatterns = [
    path('admin/', admin.site.urls),
    path('login/',view.login ),
    path('app_login/',view.app_login)

]

urlpatterns += static('/statics/', document_root=settings.STATIC_ROOT)

3、创建静态目录

root@iZuf6a01zic0bgnaiub3uoZ:/home/django_project/iot# ls
db.sqlite3  iot  manage.py  static  templates
root@iZuf6a01zic0bgnaiub3uoZ:/home/django_project/iot# ls static/

test.txt

4、访问静态文件

http://47.100.171.251:8000/statics/test.txt
