We have a program, it stores all our documents inside (as binary data).
My task is to take a binary from our system, open it in a frame in onlyoffice, edit, and save it again in our system.
To do this, I took examples from a site. And now I can open a document by direct link, install server community edition in the docker. I call saveAs and get link to the file I want to save.
Everything is great.
But, I need to send a binary file to the onlyoffice frame, I do not have an external link at all, people get access to files only from our system, so there are no direct links.
Can I solve this problem in any way?
