我做了一個(gè)小項(xiàng)目。用戶首先登錄，然后他被重定向到主頁。但是，如果用戶尚未登錄，那么如果我們粘貼該主頁的 url，該主頁也會(huì)打開。我已經(jīng)嘗試了網(wǎng)上給出的很多東西，但它不起作用。這是我的 urls.pyfrom django.conf.urls import urlfrom django.contrib import adminfrom blog import viewsurlpatterns = [    url(r'^admin/', admin.site.urls),    url(r'^$', views.login, name='login'),    url(r'^register/$', views.register, name='register'),    url(r'^home/$', views.home, name='home'),    url(r'^javaq/$', views.javaq, name='javaq'),    url(r'^javar/$', views.javar, name='javar'),    url(r'^csq/$', views.csq, name='csq'),    url(r'^csr/$', views.csr, name='csr'),    url(r'^cq/$', views.cq, name='cq'),    url(r'^cr/$', views.cr, name='cr'),    url(r'^cppq/$', views.cppq, name='cppq'),    url(r'^cppr/$', views.cppr, name='cppr'),    url(r'^pythonq/$', views.pythonq, name='pythonq'),    url(r'^pythonr/$', views.pythonr, name='pythonr'),    url(r'^mini/$', views.mini, name='mini'),]這是我的view.pyfrom django.shortcuts import renderfrom .models import logininfo,CSTEST,CTEST,CPPTEST,JAVATEST,PYTHONTEST,resultfrom django.http import HttpResponsefrom django.shortcuts import renderfrom django.contrib.auth.decorators import login_requiredfrom django.views.decorators.cache import cache_controlimport datetimedef login(request):    if request.method=="POST":        user_name=request.POST.get("username")        sid=request.POST.get("sid")        password=request.POST.get("password")        article = logininfo()        article.user_name = user_name        article.sid = sid        article.password = password        article.save()    return render(request,'login.html')def home(request):    if request.method=="POST":        sid=request.POST.get("sid")        password=request.POST.get("password")        request.session['sd'] = sid         user_obj=logininfo.objects.filter(sid=sid,password=password)        if user_obj.count()==0:            return HttpResponse("Sorry wrong password try again")    return render(request,'home.html')  def register(request):    return render(request,'register.html')
