当我在 Azure 上部署 Flask 应用程序时，视图会引发TypeError: send_from_directory() missing 1 required positional argument: 'path'. 当我在本地运行时，这不会发生。

from flask import send_from_directory

@app.route('/download/<path:filename>', methods=['GET', 'POST'])
def download(filename):
    uploads = os.path.join(app.root_path, app.config['UPLOAD_FOLDER'])
    return send_from_directory(directory=uploads, filename=filename)
