Django Ajax文件上传

Django Ajax文件上传

ajax

因此，我尝试上传没有任何外部插件的文件，但是遇到了一些错误。

                <form method="" action="" name='upload_form' id='upload_form' >
                    {% csrf_token %}
                   <input type='file' name='file' id='file' />
                   <input type='button' value='Upload' id='upload'/>
                </form>

                <script type='text/javascript'>
                $(document).ready(function() {
                    var csrf_token = $('input[name="csrfmiddlewaretoken"]').val();
                    $('#upload').click(function() {
                        $.ajax({
                            csrfmiddlewaretoken: csrf_token,
                            type: 'POST',
                            url : 'upload',
                            enctype: "multipart/form-data",
                            data  : {
                                'file': $('#file').val()
                            },
                            success: function(data) {
                                console.log(data)
                            }
                        })
                    })
                })
                </script>

我的服务器：

class ImageUploadView(LoginRequiredMixin, JSONResponseMixin, AjaxResponseMixin, CurrentUserIdMixin, View):

    @method_decorator(csrf_protect)
    def dispatch(self, *args, **kwargs):
        return super(ImageUploadView, self).dispatch(*args, **kwargs)

    def post_ajax(self, request, username):
                print request.POST.get('file', None)
                print request.FILES

        # id = request.POST['id']
        # path = 'pictures/'
        # f = request.FILES['picture']
        # destination = open(path, 'wb+')
        # for chunk in f.chunks():
        #   destination.write(chunk)
        # destination.close()
return HttpResponse("image uploaded")

我收到<MultiValueDict: {}>请求的文件。

现在如何正确获取带有我的代码的上传文件？

我遵循了本教程 http://www.script-tutorials.com/pure-html5-file-
upload/，在php部分中，我替换为：

class UploadImageView(LoginRequiredMixin, CurrentUserIdMixin, View):

    @method_decorator(csrf_protect)
    def dispatch(self, *args, **kwargs):
        return super(UploadImageView, self).dispatch(*args, **kwargs)

    def post(self, request, username):
        path = 'myproject/media/pictures/guitar.jpg'
        f = request.FILES['image_file']
        destination = open(path, 'wb+')
        for chunk in f.chunks():
            destination.write(chunk)
            destination.close()

            return HttpResponse("image uploaded")

也改变了这行

<form id="upload_form" enctype="multipart/form-data" method="post" action=".">
                                {% csrf_token %}
