Function readRequestJSON

ragserver/ragserver/json.go:17–30

readRequestJSON expects req to have a JSON content type with a body that contains a JSON-encoded value complying with the underlying type of target. It populates target, or returns an error.

(req *http.Request, target any)

// contains a JSON-encoded value complying with the underlying type of target.
// It populates target, or returns an error.
func readRequestJSON(req *http.Request, target any) error {
	contentType := req.Header.Get("Content-Type")
	mediaType, _, err := mime.ParseMediaType(contentType)
	if err != nil {
		return err
	}
	if mediaType != "application/json" {
		return fmt.Errorf("expect application/json Content-Type, got %s", mediaType)
	}

	dec := json.NewDecoder(req.Body)
	dec.DisallowUnknownFields()
	return dec.Decode(target)
}

// renderJSON renders 'v' as JSON and writes it as a response into w.
