我正在使用烧瓶来处理图像上传，每当我上传 jpg、jpeg 或 png 时，我制作的程序都能够处理上传。但是，无论何时上传 .jfif 图像，程序都会返回错误flask_uploads.UploadNotAllowed。提前感谢您的帮助！

程序有问题的代码是：

file_name = photos.save(request.files['photo'])

完整追溯：

您可能正在使用标准IMAGES集：

https://github.com/jugmac00/flask-reuploaded/blob/f05077b085393dbc607c01b8daff1b3a8b2dbf0b/src/flask_uploads/extensions.py#L29

此设置不允许.jfif文件。

但是，这样的集合实际上只是一个 Python 集合，因此您可以创建和使用自己的集合，或者只是更新现有的集合。

IMAGES.update(".jfif")
