Question: RequestBody & Multiple Content-Types (OAS3)

[jonschoning]

In 3.0.0_enhancements branch, I noticed this line:

swagger-codegen/modules/swagger-codegen/src/main/java/io/swagger/codegen/DefaultCodegen.java

Lines 3446 to 3450 in 112c1f0

	protected String getContentType(RequestBody requestBody) {
	if (requestBody == null || requestBody.getContent() == null || requestBody.getContent().isEmpty()) {
	return null;
	}
	return new ArrayList<>(requestBody.getContent().keySet()).get(0);

This appears to select the only the first content-type for a RequestBody.

What can we expect will be the plan for code generation, for the RequestBody for cases 1) and 2) below?

1) Multiple content-types with the same Schema

        "requestBody": {
          "description": "Pet object that needs to be added to the store",
          "content": {
            "application/json": {
              "schema": {
                "$ref": "#/components/schemas/Pet"
              }
            },
            "application/xml": {
              "schema": {
                "$ref": "#/components/schemas/Pet"
              }
            }
          },
          "required": false
        },

2) Multiple content-types with different Schemas

Schemas can vary by media type.

https://swagger.io/docs/specification/describing-request-body/

        "requestBody": {
          "description": "Pet object that needs to be added to the store",
          "content": {
            "application/json": {
              "schema": {
                "$ref": "#/components/schemas/Cat"
              }
            },
            "application/xml": {
              "schema": {
                "$ref": "#/components/schemas/Dog"
              }
            }
          },
          "required": false
        },
