使用authenticate()和login()功能：
from django.contrib.auth import authenticate, logindef register(request): if request.method == 'POST': form = UserCreationForm(request.POST) if form.is_valid(): new_user = form.save() messages.info(request, "Thanks for registering. You are now logged in.") new_user = authenticate(username=form.cleaned_data['username'], password=form.cleaned_data['password1'], ) login(request, new_user) return HttpResponseRedirect("/dashboard/")
