这个问题询问如何执行相反的操作，即如何使用flask上传图像并将其另存为couchdb附件.

This question asks how to perform the opposite, i.e. how can an image be uploaded using flask and saved as a couchdb attachment.

推荐答案

从看看 FileField api文档 .在那里，您可以使用流方法来访问上载的数据.除了可以使用示例中的save方法之外，您还可以访问流中的字节，对base64进行编码并将其另存为例如ouchdb中的附件.使用 put_attachment .另外，FileStorage api文档建议您可以使用read()检索数据.

Take a look at the FileField api docs. There you have a stream method giving you access to the uploaded data. Instead of using the save method as in the example you can access the bytes from the stream, base64 encode it and save as an attachment in couchdb, e.g. Using put_attachment. Alternatively, the FileStorage api docs suggest you can use read() to retrieve the data.
