Hi @vinuu123 I am referring the API to the external URL. You can get it via annoations.

@Inject
@Optional
@Named("externalUrl")
protected String externalUrl;

Thanks

Hi @vinuu123

I am not sure if I am exactly following the requirement here but in case your ask is to invoke the servlet from dialog you can try the implementation in the below link.

You can also bind with a slingmodel in backend and then read the content in backend with URL configured from the dialog also and can avoid servlet if that works.

Hi @vinuu123 You can read the value of the URL in the sling dialog and then use the below code to get the extract of the entire html section

@Model(adaptables = {Resource.class, SlingHttpServletRequest.class}, defaultInjectionStrategy = DefaultInjectionStrategy.OPTIONAL)
public class HtmlModel{

    private static final Logger logger = LoggerFactory.getLogger(HtmlModel.class);

    @Getter
    private String body;

    @PostConstruct
    void init() {
        final String api = <read it from dialog>;
        final HttpGet httpRequest = new HttpGet(api);
        try (final CloseableHttpResponse response = HttpClients.createDefault().execute(httpRequest)) {
            body = IOUtils.toString(response.getEntity().getContent(), StandardCharsets.UTF_8);
        } catch (final IOException e) {
            logger.error("IOException while reading HTML API %s: ", e);
        }
    }

}

Hope this helps!

Thanks

Hi @vinuu123

I'm curious about the choice not to use an iframe to embed external URL. Could you provide insight that influenced this decision?
