flask怎么实现多图上传

$('#form-name').submit(function(){

    $(this).ajaxSubmit({

        # 访问后端的接口

        url:'/house/images/',

        # 请求的方式

        type:'POST',

        # 数据的类型

        dataType:'json',

        # 请求成功，进行的操作

        success:function(data){

            if (data.code == '200'){

            }  

        }，

        # 请求失败进行相应的操作

        error:function(data){

            alert(data.msg)

        } 

   })

image_url = os.path.join(os.path.join('/static', 'upload'), images.filename)

@house_blueprint.route('/images/', methods=['POST']) def newhouse.images():

    # 获得图片(images:<FileStorage: 'wa.jpg' ('image/jpeg')>)

    images = request.files.get('house_image')

    house_id = request.form.get('house_id')

    # 得到upload的路径

    upload_dir = os.path.join(os.path.join(BASE_DIR,'static'), 'upload')

    # 得到上传图片要保存的路径

    # 'D:\\project\\houseproject\\static\\upload\\wa.jpg'

    # 保存图片

    images.save(url)
