application/octet-stream binary data?

[RPGillespie6]

How would I specify that the request or response body is a binary payload of type application/octet-stream?

Basically, I want it to generate:

      requestBody:
        content:
          application/octet-stream:
            schema:
              type: string
              format: binary
              description: Raw bytes of the data

I've tried:

type req struct {
    Body []byte `format:"binary"`
}

type req struct {
    Body string `format:"binary"`
}

etc, but can't find any docs. Anyone know? I will submit a PR to improve the docs if I can figure it out.

You can achieve that with a customized content unit. Please check an example:

https://go.dev/play/p/9uH7zLRS60R

package main

import (
	"encoding/json"
	"net/http"

	"github.com/swaggest/openapi-go"
	"github.com/swaggest/openapi-go/openapi31"
)

func main() {
	r := openapi31.NewReflector()

	oc, _ := r.NewOperationContext(http.MethodGet, "/")

	oc.AddReqStructure(nil, func(cu *openapi.ContentUnit) {
		cu.ContentType = "application/octet-stream"
		cu.Format = "binary"
		cu.Description = "Raw bytes of the data"
	})

	_ = r.AddOperation(oc)

	j, _ := json.MarshalIndent(r.SpecSchema(), "", " ")
	println(string(j))
}

{
 "openapi": "3.1.0",
 "info": {
  "title": "",
  "version": ""
 },
 "paths": {
  "/": {
   "get": {
    "requestBody": {
     "description": "Raw bytes of the data",
     "content": {
      "application/octet-stream": {
       "schema": {
        "format": "binary",
        "type": "string"
       }
      }
     }
    },
    "responses": {
     "204": {
      "description": "No Content"
     }
    }
   }
  }
 }
}

Awesome, thank you very much for the help. I'm going to open a few PRs once I understand this library a little better to add more examples like this if that's ok
