REST API，用于在JSON中上传文件

Question

I am designing an REST API to upload a largish (100MB) file together with some information. So it's natural to think of json encoding.

So something like this:

{
   file: content of the file or URL?
   name: string
   description: string
}

The name and description are easy to do with json but I'm not sure how the file content can be added to it.

Also I'm thinking I should use http PUT method. Is this correct?

Incidentally, golang is used to implement this API if it matters.

Answer 1

To me, the most clear-cut way to do it would be to encode the file bytes somehow. base64 seems like a good choice, and golang has built-in support for it with "encoding/base64".
