Answer 1

您可以使用SlingRequestProcessor在服务器端获得呈现的HTML。

来自@Nateyolles博文：

在Apache sling中获取资源的HTML标记。

@SlingServlet(paths={"/bin/foo"})
public class SlingResourceResolutionServlet extends SlingSafeMethodsServlet {

    /** 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 = "/content/myapp/us/en/index/jcr:content/myparsys/mycomponent_f93d.html";

        /* 
         * Create a fake request and fake response. The response adds a method to make the HTML accessible.
         * You need the following three files from Apache Sling:
         *
         * https://github.com/apache/sling/blob/trunk/testing/junit/scriptable/src/main/java/org/apache/sling/junit/scriptable/HttpRequest.java
         * https://github.com/apache/sling/blob/trunk/testing/junit/scriptable/src/main/java/org/apache/sling/junit/scriptable/HttpResponse.java
         * https://github.com/apache/sling/blob/trunk/testing/junit/scriptable/src/main/java/org/apache/sling/junit/scriptable/TestServletOutputStream.java
         */
        final HttpRequest req = new HttpRequest(requestPath);
        final HttpResponse resp = new HttpResponse();

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

@SlingServlet(paths={"/bin/foo"})
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 = "/content/myapp/us/en/index/jcr:content/myparsys/mycomponent_f93d.html";

        /* 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();
    }
}
