前端通过ajax将文件传给Django后端

html

<form action="" id="form_data" method="post" enctype="multipart/form-data" onsubmit="return false">
      
                    <input type="submit" class="btn btn-default" id="export_file" value="导入">
               
            </form>

js

 $('#export_file').click(function () {

            var objFile = document.getElementById("file_");
            if(objFile.value === "") {
            alert("不能空")
                return;
             }

        $.ajax({
            url: '/test/',
            method: 'POST',
            traditional: true,
            processData: false,
            contentType: false,
            cache: false,
            data: new FormData($('#form_data')[0]),
            success:function (res) {

            },
            error: function () {

            }
        })


        })

后端Django处理

def export_idc_special(request):
    if request.method == 'GET':
        return render(request, 'asset/idc/export_idc_special.html', locals())
    elif request.method == 'POST':
        try:
            print '-------------'
            print request.FILES
            # 获取前端传递过来的数据进行保存
            file_obj = request.FILES.get('file', '')
            file_mame = "Lib/" + str(uuid.uuid1()) + '.xlsx'
            with open(file_mame, 'wb+') as f:
                for chunk in file_obj.chunks():
                    f.write(chunk)
          

        except Exception as e:
            print e
