Custom Web Script for document Download

[cris_cc]

Hello everyone,
I need to write a custom Web Script in order to download a file from the repository.
I know that there are native services to do that, but I need to validate the document id through other back-end systems using remote.call

Here what I've done so far in the cstdownload.get.js :

var nodeid = args.nodeid;

if ( crossCheck(nodeid) ){ // This is a Custom function!!!
    
    var file = search.findNode("workspace://SpacesStore/" + nodeid);

   // Render the content of the file here !!! HELP pls!!
   
}else{
    status.code = 400;
    status.message = "Check on back-end system is failed!";
    status.redirect = true;
}

function crossCheck(nodeid){
…..
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Does anyone have some suggestion where I can find some good example to do that?

I checked the forum and alfresco docs, but I've just found example about native services.

I'm running Alfresco Community v3.2.0 (r2 2440).

Thanks in advance,
Cris

Dear Cris,

You can use

var fileDownLoadUrl = file[0].downloadUrl;‍

If this does`nt work then in the ftl you can use

${file[0].downloadUrl}‍

Hi Amarendra,
thanks for your reply.

But the solution you sent is not helping me.

Basically the following code:

var fileDownLoadUrl = file.downloadUrl;‍

just produce the service path to use to download the file (something like "/d/a/workspace/SpacesStore/eb0d2fa7-ff5f-440c-9f49-6edc4036b6ce/mypic.jpg"), and it could be used in the xml/html output (ie: cstdownload.get.xml.ftl) as link to the file download.

What I'm looking for is how to stream the file directly from the Web Script.

Thanks,
Cris

Take a look at enabling the remote object http://drquyong.com/myblog/?p=49 in the core repository.
