Django[WinError 10053]在AJAX POST上

我正在用Django制作一个网站,它使用AJAX将一些信息发布到后端。本例中的信息是用户键入的总时间(从开始键入时起)到按submit时的总时间。但是,由于某些原因,我一直在命令提示符下看到错误。浏览器控制台只有0:,这表示POST中的错误。我在视图中有一组print语句,它们处理post(passage_result)来帮助定位错误,而且它似乎与return HttpResponse(json.dumps(response_data), content_type="text/html")行有关,因为每个print语句都返回预期的答案。在

错误如下:

以下是passage_result视图:

^{pr2}$

这是我的jQuery代码:

//Create a time so we can update it later
var time = (new Date()).getTime();

//function to update the time when the user starts typing
$('#id_user_passage').on('keyup', function (event) {
    event.preventDefault();
    time = (new Date()).getTime();
});

// function to get the total time the user typed from when he started to when
// he clicked the submit button, and POST the information to the backend,
// along with what he typed and when he submitted it.
 $('#passage_result_form').on('submit', function(event) {
     event.preventDefault();
     var total_time = (new Date()).getTime() - time;
     var current_time = (new Date()).getTime();
     console.log('Time passed : ' + total_time + ' milliseconds');
     console.log('form submitted!')
     $.ajax({
         url: "/typer/passage_result/",
         type: "POST",
         data: { 'user_passage': $('#id_user_passage').val(), 'original_passage': $("#name").text(), 'time_taken': total_time,
         'creation_time' : current_time},

         success: function (json) {
             total_time = 0;
             console.log(json);
             console.log("success");
         },

         error: function (xhr, errmsg, err) {
             $('#results').html("<div class='alert-box alert radius' data-alert>Oops! We have encountered an error: " + errmsg +
                 " <a href='#' class='close'>&times;</a></div>");
             console.log(xhr.status + ": " + xhr.responseText);
         }
     });
     location.replace('/typer/result/');

 });
