必须将烧瓶静态文件夹放置在项目根目录之外

Question

我需要将所有静态文件存储在项目文件夹之外。虽然我像下面更新了我的烧瓶配置，但仍然没有将图像保存在该文件夹中...

app = Flask(__name__, static_folder='../Storage/static', static_url_path='/storage')

但是当我尝试使用下面的代码保存文件时，它总是将图像存储在project_folder-> static中

def save_image(image: FileStorage, folder: str = None, name: str = None) -> str:
    return IMAGE_SET.save(image, folder, name)

需求示例：

当前

project_folder/
               static/
                      images/

需要存储类似

Storage(parallel folder)/
               static/
                     images/   

请帮助，我尝试了以下链接，但没有帮助...

下面是我的测试代码，在运行代码之前，应先创建文件夹“ ../Storage/static/images”，或先使用os.makedirs（）进行创建：

import sys,os
from flask import  Flask
from werkzeug.datastructures import FileStorage
file = None
fp=open('110326-666286.jpg', 'rb')
file = FileStorage(fp)

app=Flask(__name__)
app.debug=True

def save_image(image: FileStorage, folder: str = None, name: str = None) -> str:
    if not os.path.exists(folder):
        os.makedirs(folder)
    return image.save(folder+'/'+name)

@app.route('/hello/<name>/<surname>')
def hello(name,surname):
  save_image(file,'../Storage/static/images','110326-666286_.jpg')
  if os.path.exists('../Storage/static/images'+'/'+'110326-666286_.jpg'):
    res='image saved'
  else:
    res='image not saved'
  return '<h1>hello, %s %s</h1><p>%s</p>'%(name,surname,res)



if __name__=='__main__':
  app.run(host='127.0.0.1',port=8080)

下面是结果
