def login(request):

if request.method == "GET":

return render(request, 'login.html')

elif request.method == "POST":

username = request.POST.get('username','')

password = request.POST.get('password','')

print username, password

  models.UserInfo.objects.create(user=username, password=password)
    result = models.UserInfo.objects.filter(user=username,password=password)
    resulta = models.UserInfo.objects.filter(user=username,password=password).first()
    if result:
 print result
 print resulta
    else:
 return HttpResponse('用户名或密码错误')
return render(request, 'index.html', {'result': result})
