How to implement upload of many files + json on FLASK?

Question

RESTful API

I would like to send a request to the multipart server that includes JSON and an array of files.
You can describe the request like this:

requestBody:
        content:
          multipart/form-data:
            schema:
              type: object
              properties:
                orderId:
                  type: integer
                userId:
                  type: integer
                filename:
                  type: array
                  items:
                    type: string
                    format: binary

What is the correct way to get multiple files using Flask? Maybe there is an example?
Thank you.

Answer 1

like with any other (except sockets) - in a loop one by one
