Thank you very much for the code!
请问，用Flask_uploads做了一个上传手机照片的页面，但偶尔还是会有
raise UploadNotAllowed()
flask_uploads.UploadNotAllowed
想用try/except查找此情况下上传文件的扩展名。
但是：
except UploadNotAllowed as error:
会报错：
NameError: name 'UploadNotAllowed' is not defined
还试过flask_uploads.UploadNotAllowed或flask_uploads，但都说没定义。
请问这里该怎么写？感谢~
I using Flask_uploads to make a page to upload mobile photos,
but occasionally there still be
raise UploadNotAllowed()
flask_uploads.UploadNotAllowed
I want to use try / except to find the extension of the uploaded file.
but:
except UploadNotAllowed as error:
Will report an error:
NameError: name 'UploadNotAllowed' is not defined
I also tried flask_uploads.UploadNotAllowed or flask_uploads, but they all undefined.
What should I write here? thank~
