get resourceRequest without serveResource()

[7年前 に Madasamy P によって更新されました。]

Can I get resourceRequest and resourceResponse without using serveResource() method?

setupResponseHeaders(folderName,resourceRequest, resourceResponse);
try{
zip = new ZipOutputStream(resourceResponse.getPortletOutputStream());
if(path.equals(""))
addFilesToZip(groupId,folder,folder.getName(),zip);

}

private void setupResponseHeaders(String folderName,ResourceRequest resourceRequest, ResourceResponse resourceResponse) {

String zipFileMimeType = "application/zip";
resourceResponse.setContentType(zipFileMimeType);
int multipleFileDownloadCacheMaxAge = DEFAULT_DL_FILE_DOWNLOAD_CACHE_MAX_AGE;
if (multipleFileDownloadCacheMaxAge > 0) {
String cacheControlValue = "max-age=" + multipleFileDownloadCacheMaxAge + ", must-revalidate";
resourceResponse.addProperty("Cache-Control", cacheControlValue);
}

String zipFileName = folderName+"_" + new Date().getTime() + ZIP_FILE_EXT;
String contentDispositionValue = "attachment; filename=\"" + zipFileName + "\"";
resourceResponse.addProperty("Content-Disposition", contentDispositionValue);
resourceResponse.setProperty("Transfer-Encoding", "chunked");
}

I think without request and response the zip download not possible
But I don't use any user interaction( button click ), so I can't using serveResource ,So I can't get the value for resourceRequest and resourceResponse variable to set the response as download

What makes you think that you can trigger a download through anything if not the browser? It doesn't matter if it's an actual user's click or some javascript: As long as there's no request, there's no response, i.e. no download of anything. The request initiates everything - and you just need to make sure that the request is directed to the portlet's resourceURL.

resourceRequest and resourceResponse are defined only within serveResource - getting them elsewhere than in this lifecycle method is, IMHO, an invalid attempt.

Ok Thank you Kock for your information
If there any other way to rectify it?

What do you mean with "it"? Triggering a download from something else than the browser? Serving a resource without serving a resource? Triggering a download without user interaction (what would be the trigger alternatively?)?

Serving a resource without serving a resource
That means user requests to zip for given folderId and I give an response to the user as zipOutputStream by creating service method (zipAndDownload)
The user requested from api/jsonws and I have to provide an response as zipoutputstream through api and downloaded to user system
In these, the problem is no need to resourceRequest but I want resourceResponse to set response Headers and contents to download
So thst's why I asking this
