配置路由
首先分发路由[User,Blog,Article]
from django.contrib import admin
from django.urls import path
from Blog import views
from django.conf.urls import includeurlpatterns = [path('admin/', admin.site.urls),path('', views.home, name='home'),path('User/', include('User.urls', namespace='User')),path('Blog/', include('Blog.urls', namespace='Blog')),path('Article/', include('Article.urls', namespace='Article')),
]
配置路由
urlpatterns = [path('register/', views.register, name='register'),path('login/', views.login, name='login'),# 返回图片路由path('get_verify_img/', views.get_verify_img, name='get_verify_img'),path('blog/', views.blog, name='blog'),
]
首页
def home(request):if request.session.get('user'):online_user = request.session.get('user')else:online_user = '登录'return render(request, 'home.html', locals())
