使用django 1.10.5的Ajax Post请求错误。

Over the last week or so I have been struggling to successfully implement a jQuery ajax request to pass data from a javascript function within my annualgoals.html to a django view in order to save data to my database. Currently I am just trying to test the data transfer by printing the data on the django end.

在过去的一周左右，我一直在努力成功地实现jQuery ajax请求，以便在我的年度目标中从javascript函数中传递数据。将html保存到django视图，以便将数据保存到数据库。目前我正在尝试通过在django端上打印数据来测试数据传输。

I have already checked out the following threads but cannot see any that show the same error as I can see (I am almost certainly missing something obvious).

我已经检查了下面的线程，但是没有看到任何线程显示与我看到的相同的错误(我几乎肯定漏掉了一些明显的错误)。

Forbidden (CSRF token missing or incorrect) Django error

禁止(CSRF令牌丢失或不正确)Django错误

"CSRF token missing or incorrect" while post parameter via AJAX in Django

“CSRF令牌丢失或不正确”，同时通过AJAX在Django中发布参数

While a missing CSRF token was my first problem, the answers on * and the django docs do a good job of explaining what must be done to ensure the csrf token is included. However, when following the recommended steps I receive the following django error:

虽然丢失的CSRF令牌是我的第一个问题，但是*和django文档上的答案很好地解释了必须做什么才能确保包含CSRF令牌。但是，当按照推荐的步骤执行时，我收到以下django错误:

response.set_cookie(settings.CSRF_COOKIE_NAME, AttributeError: 'NoneType' object has no attribute 'set_cookie'

response.set_cookie(设置。CSRF_COOKIE_NAME, AttributeError: 'NoneType'对象没有属性'set_cookie'

My code is as follows:

我的代码如下:

annualgoals.html

function getCookie(name) {
          var cookieValue = null;
          if (document.cookie && document.cookie !== '') {
              var cookies = document.cookie.split(';');
              for (var i = 0; i < cookies.length; i++) {
                  var cookie = jQuery.trim(cookies[i]);
                  // Does this cookie string begin with the name we want?
                  if (cookie.substring(0, name.length + 1) === (name + '=')) {
                      cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                      break;
                  }
              }
          }
          return cookieValue;
      }

function csrfSafeMethod(method) {
          // these HTTP methods do not require CSRF protection
          return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
      }

var data = [1, 2, 3, 4]
var csrftoken = getCookie('csrftoken');

// Ajax Setup

    $.ajaxSetup({
       beforeSend: function(xhr, settings) {
          if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
                    xhr.setRequestHeader("X-CSRFToken", csrftoken);
                }
          }
    });

 // Ajax Call

    $.ajax({
      type: 'POST',
      url: "{% url 'LifeAdmin:saveAnnualGoals' %}",
      data: {'data[]': data},
    });

views.py

@ensure_csrf_cookie
@login_required
def saveAnnualGoals(request):
   if request.method == 'POST':
       data = request.POST.get('data')
   print(data)

urls.py

urls . py

url(r'^saveAnnualGoals$', views.saveAnnualGoals, name='saveAnnualGoals')

Your view needs to return a Response. With your actual code, the view returns nothing, so None. Django then tries to add the cookie to the Response but as it is None, you get the error message you posted.

您的视图需要返回一个响应。对于实际的代码，视图不返回任何东西，所以没有。Django尝试将cookie添加到响应中，但是因为它不是None，所以您将获得您所发布的错误消息。

例子:

return HttpResponse(status=200)
