发送数据时出现问题。

当我用来发布数据并接受视图时，一切正常JSON.stringifyjson.loads(request.POST.get('frm'))

$('#messageform').on('submit', function(e) {

  e.preventDefault();

  var frm = {

    'user_id': $('#user_id').attr('value'),

    'text': $('#form_message').val()

  };

  frm = JSON.stringify(frm);

  

  $.ajax({

    type: 'POST',

    url: "message/message_form/",

    dataType: 'json',

    data: {

      csrfmiddlewaretoken: "{{ csrf_token }}",

      'frm': frm

    },

  })

});

views.py

def post(self, request):

        dictionary = json.loads(request.POST.get('frm'))

        print('=================',dictionary)

        u = get_object_or_404(User,pk=dictionary['user_id'])

        msg = message.objects.filter(sender=request.user).filter(receiver=u).all() | message.objects.filter(sender=u).filter(receiver=request.user).all()

        u = message.objects.create(sender=request.user,receiver=u,text=dictionary['text'])

        #if request.user != u and u.objects.filter(receiver__sender=request.user,receiver__receiver=u,receiver__read=False).exists :

        #    notify.send(request.user, recipient=u, verb="message you please read in message box",public=False)

        # msg = message.objects.filter(sender=request.user).filter(receiver=u).all() | message.objects.filter(sender=u).filter(receiver=request.user).all() 

        msg = dictionary['text']

        data = { "message":msg}

        return HttpResponse(json.dumps(data), content_type='application/json')
