发现用用户名登陆可以跳转主页面，只有在用邮箱登陆的时候不会跳转进主页面，但是打开主页显示是登陆状态。

class CustomBackend(ModelBackend):
def authenticate(self, request, username=None, password=None, **kwargs):
try:
user = UserProfile.objects.get(Q(username=username)|Q(email=username))
if user.check_password(password):
return user
except Exception as e:
return None

class LoginView(View):
def get(self, request):
return render(request, 'login.html', {})
def post(self, request):
login_form = LoginForm(request.POST)
# 判断是否合法
if login_form.is_valid():
user_name = request.POST.get('username', '')
pass_word = request.POST.get('password', '')
user = authenticate(username=user_name, password=pass_word)
if user is not None:
if user.is_active:
login(request, user)
return render(request, 'index.html')
else:
return render(request, 'login.html', {'msg': '用户未激活！'})
else:
return render(request, 'login.html',{'msg': '用户名或密码错误！'})
else:
return render(request, 'login.html', { 'login_form':login_form})
