Django ajax传参数

ajax传递参数：

function select_img(index) {
     $("#demo-origin-idcard").html("<br /><img src='/static/demo-card-"+index+".png'>");
        $.ajax({
        url:'/idcard_ocr_by_name',
        type:'POST',
        data: JSON.stringify({type:'model', filename:index}),
        dataType:'json',
        contentType: false, // tell jquery not to set contentType
        success: function(callback) {
            var json = eval('(' + callback + ')');
            var eValue=json['data'];
            $("#demo-result-idcard").find(".card-no").html(eValue['numstr']);
        }
    }); // end ajax
}

获取参数:

param= json.loads(request.body.decode('utf-8'))

file_name= param["filename"]
