Resolve external ref from data

[wangyoucao577]

When using external ref, currently there're two ways to resolve the references when loading swagger: #245 (comment) and #245 (comment). However, both ways requires path(URL or local file) for the resolving.

Is it possible to provide another API (e.g., LoadSwaggerFromDataWithData) that able to resolve external ref by loaded data?

Thanks!

I'm using deepmap/oapi-codegen to generate Go codes from OpenAPI 3, which will generate swaggerSpec along with code, e.g., https://github.com/deepmap/oapi-codegen/blob/fbeefa1d08cc055289fd6d7c10dee27088b51136/examples/petstore-expanded/chi/api/petstore.gen.go#L252.

In my usage, there's no more yaml files when application run, only all the swagger spec data. This workaround is not work for me.

Thanks!

Here's an example of how to use loader.ReadFromURIFunc and/or go embed

kin-openapi/openapi3/testdata/load_with_go_embed_test.go

Lines 5 to 33 in 1715334

	import (
	"embed"
	"fmt"
	"net/url"
	"github.com/getkin/kin-openapi/openapi3"
	)
	//go:embed recursiveRef/*
	var fs embed.FS
	func Example() {
	loader := openapi3.NewSwaggerLoader()
	loader.IsExternalRefsAllowed = true
	loader.ReadFromURIFunc = func(loader *openapi3.SwaggerLoader, uri *url.URL) ([]byte, error) {
	return fs.ReadFile(uri.Path)
	}
	doc, err := loader.LoadSwaggerFromFile("recursiveRef/openapi.yml")
	if err != nil {
	panic(err)
	}
	if err = doc.Validate(loader.Context); err != nil {
	panic(err)
	}
	fmt.Println(doc.Paths["/foo"].Get.Responses["200"].Value.Content["application/json"].Schema.Value.Properties["foo"].Value.Properties["bar"].Value.Type)
	// Output: array

If that doesn't work for you, can you explain further your LoadSwaggerFromDataWithData idea?
