django 错误：[Errno 32] 我进行 ajax 调用时管道损坏

Question

每次我发出 ajax 请求时都会收到此错误，仅在此项目中。 涉及的代码如下：

[JS AJAX 调用]

    var url = '/eden/find_flights/';
    var csrf_token = getCookie('csrftoken');

    $.ajax({
        'url': url,
        'data':  {
            'trip': JSON.stringify(trip),
            'travellers': JSON.stringify(travellers),
            'csrfmiddlewaretoken': csrf_token
        },
        'type': 'POST',
        'dataType': 'json',
        'complete': function(response) {

            $("#result").html(response.responseText); //.animate({'marginTop': "-=700px"}, 'slow', 'swing', function() {});
        },
    });

[views.py]

@csrf_exempt
def find_flights(request):

    flights = {}

    return render_to_response('flight_search_results.html', flights, context_instance=RequestContext(request))

dict 航班将充满数据，但现在并不重要。我得到的问题是在萤火虫中获得一条红线（如错误），但没有错误信号（如果我使用“在新选项卡中打开”选项我得到一个空白页）并且在 django 控制台中：

我已经寻找过这个错误，但我无法理解 wtf 导致它的原因，也不知道我能做些什么来避免它。

你有这个代码：

var url = '/eden/find_flights/';
var csrf_token = getCookie('csrftoken');

$.ajax({
    'url': url,
    'data':  {
        'trip': JSON.stringify(trip),
        'travellers': JSON.stringify(travellers),
        'csrfmiddlewaretoken': csrf_token
    },
    'type': 'POST',
    'dataType': 'json',
    'complete': function(response) {

        $("#result").html(response.responseText); //.animate({'marginTop': "-=700px"}, 'slow', 'swing', function() {});
    },
});

这是否属于.submit() 事件处理程序？如果是这样，请让您的event 致电preventDefault。否则，您的页面将加载并停止 ajax 调用。
