Get the XF Page source code in Java

[test566]

Hi All,

anyone know how to get the source code of XF 

below i tried but its giving an null pointer error  .

private String getExperienceFragmentHtml(SlingHttpServletRequest request) throws ServletException, IOException {
        ResourceResolver resourceResolver = request.getResourceResolver();
        Resource xfResource = request.getResource();
        String xfPath = xfResource.getPath();
        Page xfPage = resourceResolver.getResource(xfPath).adaptTo(Page.class);
        String html = "";

        if (xfPage != null) {
            try {
                // Create a StringWriter to capture the HTML source code
                StringWriter writer = new StringWriter();
                // Create a PrintWriter with the StringWriter
                PrintWriter printWriter = new PrintWriter(writer);
                // Create a new HtmlLibraryManager instance
                HtmlLibraryManager htmlLibraryManager = resourceResolver.adaptTo(HtmlLibraryManager.class);
                
             HtmlLibrary xfHtmlLibrary = htmlLibraryManager.getLibrary(xfPage, request);
                
                 xfHtmlLibrary.include(request, printWriter, true);
                // Get the HTML source code from the StringWriter
                html = writer.toString();
            } catch (Exception e) {
                // Handle any exceptions
                e.printStackTrace();
            }

        }
        LOG.info("HTML" + html);
        return html;

    }

@test566 You can try like below

public class AemResourceResolutionServlet extends SlingSafeMethodsServlet {

    /** Service to create HTTP Servlet requests and responses */
    @Reference
    private RequestResponseFactory requestResponseFactory;

    /** Service to process requests through Sling */
    @Reference
    private SlingRequestProcessor requestProcessor;

    @Override
    protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {

        /* The resource path to resolve. Use any selectors or extension. */
        String requestPath = "<XF path>";

        /* Setup request */
        HttpServletRequest req = requestResponseFactory.createRequest("GET", requestPath);
        WCMMode.DISABLED.toRequest(req);

        /* Setup response */
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        HttpServletResponse resp = requestResponseFactory.createResponse(out);

        /* Process request through Sling */
        requestProcessor.processRequest(req, resp, request.getResourceResolver());
        String html = out.toString();
    }
}

Hi @test566 ,

You can use service user to get the session so that resource can able access path, we had the same issue.

Thank,
