一、首页
路由
from django.contrib import admin
from django.urls import path, re_path
from app01 import views
from django.views.static import serve
from django.conf import settings
urlpatterns = [
path('admin/', admin.site.urls),
path('register/', views.register),
path('login/', views.login),
path('get_code/', views.get_code),
path('home/', views.home),
path('logout/', views.logout),
path('set_password/', views.set_password),
re_path('media/(?P.*)', serve, {'document_root': settings.MEDIA_ROOT}),
re_path('(?P\w+)/(?Pcategory|tag|archive)/(?P.*)', views.site),
re_path('(?P\w+)', views.site),

2.首页之后端
def home(request):
'''
media文件的开放：
首先需要在配置文件 settings.py 中加入下面这行代码：
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
以后再次注册账户的时候，图片就上传到 media/avatar 文件夹下了,
但是，当你在前端的 img 的 src="/media/{{ article.blog.userinfo.avatar }}",
还是不能显示图片，这也说名还没有开放 media 文件夹权限，需要在路由 urls.py 文件中
加入:
from django.views.static import serve
from django.conf import settings
re_path('media/(?P.*)', serve, {'document_root': settings.MEDIA_ROOT}),
这个时候图片才能正常的显示在页面
:param request:
:return:
'''
