Django：在ajax调用上login_required [英] Django: login_required on ajax call

问题描述

我正在尝试在ajax文章上验证用户，但不起作用。这里我做了什么

I am trying to authenticate user on ajax post but doesn't work. Here what I have done

settings.py

LOGIN_URL = '/accounts/login/'
LOGIN_REDIRECT_URL = '/'

模板

<script>
  $('.btn-request').click(function(){
        var button = this;
        $.ajax({
                 type: "POST",
                 url: "{% url 'like' %}",
                 data: {'tutorial_id': $(this).attr('name'), 'csrfmiddlewaretoken': '{{csrf_token}}'},
                 dataType: "json",
                 success: function(json) {
                    toastr.success(json.message);

                  },
                  error: function(rs, e) {
                        alert(rs.responseText);
                  }
            });
      })
  </script>

urls.py

url(r'^like/$', 'apps.quotation.views.like', name='like'),

views.py - 尝试1

@login_required
def like(request):
        vars = {}
        if request.method == 'POST':
            response_dict = {}

            if not something:
                response_dict.update({'message': "Requested" })
            else:
                response_dict.update({'message': "You have already requested" })

        return HttpResponse(simplejson.dumps(response_dict),
                        mimetype='application/javascript')

views.py - 尝试2

def like(request):
    if not request.user.is_authenticated():
        return HttpResponseRedirect('/accounts/login')
    else:
        vars = {}
        if request.method == 'POST':
            response_dict = {}
            if not something:
                response_dict.update({'message': "Requested" })
            else:
                response_dict.update({'message': "You have already requested" })

        return HttpResponse(simplejson.dumps(response_dict),
                        mimetype='application/javascript')

Runserver日志

[05/Mar/2014 05:19:16] "POST /like/ HTTP/1.1" 302 0
[05/Mar/2014 05:19:16] "GET /accounts/login/?next=/like/ HTTP/1.1" 200 5610

我缺少什么？

推荐答案

而不是：

if not request.user.is_authenticated():
   return HttpResponseRedirect('/accounts/login')

return json response：

return json response :

if request.user.is_authenticated():
    ## write your code...
    jsonr = json.dumps({ 'authenticated': True })
    return HttpResponse(jsonr, mimetype='application/json')
else:
    jsonr = json.dumps({ 'authenticated': False })
    return HttpResponse(jsonr, mimetype='application/json')

在你的ajax成功响应，如果不通过身份验证，然后使用 windows.location 重定向到登录。

And At your ajax success response , if not authenticated then redirect to login using windows.location .
