TypeError：__ call __（）得到一个意外的关键字参数'mimetype'

Question

使用重定向在flask中发送响应会出现此错误：

TypeError: __call__() got an unexpected keyword argument 'mimetype'

以下是完整的跟踪：

Traceback (most recent call last):

烧瓶代码是：

@app.route('/', methods=['GET', 'POST'])
def index():
    global image,pipeline

    uform = UploadForm()
    pform = PipelineForm()

    if pform.validate_on_submit():
        operation = pform.select_op.data
        op = lst[operation][1]
        pipeline.append(op)

        if image != None:
            file_location = os.path.join(app.static_folder, image)
            script_location = os.path.join(app.static_folder, "scripts/"+pipeline[-1]+".py")
            print file_location, script_location
            call(["python",script_location,file_location])


    elif uform.validate_on_submit():
        if hasattr(uform.image_file.data,'filename'):
            pipeline = []
            image = 'temp/' + uform.image_file.data.filename
            uform.image_file.data.save(os.path.join(app.static_folder, image))

    Response = make_response(render_template('index.html', uform=uform, pform=pform, image=image, pipeline = pipeline))
    return redirect(url_for("index"),code=200,Response=Response)
