Can not read binary content fron input stream

wael_shaban

I have Alfresco deployed on LR 4.2.1. And I am creating LR portlet for uploading and playing/converting media files. I am using Alfresco web-service API to save the media files inside the Alfresco repository.
All goes well with me with creating folders, creating content and saving the content (file bytes). I am also can open the alfresco space through the browser and see my file there and can download it with no problems.

My problem exist when I am trying to download the file using the web-service API to play it inside the portlet.
My code is:

AuthenticationUtils.startSession(USERNAME, PASSWORD);
Reference reference = new Reference(STORE, null, "/app:company_home/cm:"+userID+"/*[@cm:name=\"" + vid_.getName() + "\"]");

Node[] nodes = WebServiceFactory.getRepositoryService().get(new Predicate(new Reference[]{reference}, STORE, null));
         
if (nodes!=null && nodes.length>0){
            
    Content[] readResult = WebServiceFactory.getContentService().read(
                        new Predicate(new Reference[]{nodes[0].getReference()}, STORE, null), 
                        Constants.PROP_CONTENT);

    Content content = readResult[0];
            
    InputStream inputStream = ContentUtils.getContentAsInputStream(content);

    byte[] contentBytes = new byte[(int)content.getLength()];
    inputStream.read(contentBytes);
    vid_.setContent(contentBytes);
    inputStream.close();
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

where "vid_" is my object that holds the media name and content. After that I save the file bytes inside tmp file to stream it to my media player.

But when I ran this code, I found Alfresco server have the following error logs:

Any advices please?
It is too urgent for me.

stefan_0807

Perhaps this can help you:

            Content content = readResult[0];

            FileOutputStream os = new FileOutputStream("OutOfAlfresco.pdf");
            ContentUtils.copy(ContentUtils.getContentAsInputStream(content), os);‍‍‍‍

Thanks very much, stefan. It works well with me now.

I have another question if you can help in it. As I said, I use Alfresco to store my media files for my web-application. But the problem is that my media player must have a URL to the media file without any parameters attached to it. i,e.
http://localhost:8080/project/media.flv

But to stream out of Alfresco, you must provide the security ticket as parameter in the URL to bypass the login page. To solve this problem, I checkout the file from Alfresco as you see in my post and put it inside my application context to be streamed by the media player.

My question is:
Do you have any idea about streaming out the content from Alfresco without providing the ticket as parameter in the URL?

Thanks again

stefan_0807

Hi.

I don't think that's possible to grab for content without the identification and so the media player has to identify himself against alfresco too. The only way I see without a parameter in the URL is that the player or the surrounding program identify himself in a sepperate step before asking for the URL.

I think you solved the problem very well by checking out the content. If you find a better way, please notify me so I can advance my experience.

kevinr

You could give the Guest user access to the content, and then create URLs using the guestDownload servlet instead of the download servlet, so something like this:
http://localhost:8080/alfresco/guestDownload/direct/workspace/SpacesStore/41bc32ab-fa4d-11db-8f6f-096e12a60898/myfile.wmv

Or you could create some kind of http proxy class that converts your simple URLs into full alfresco URLs, and then just point your media player to the simple URL proxy.

Thanks,

Kevin
