What you're seeing is an empty zip file when trying to download the item. That's because the permission check failed, which is actually a bug on our side because we are redirecting to a new controller that doesn't know about the api auth mechanism.<div>
<br></div><div>As a workaround, is your client able to handle cookies? If so, you could use session-based authentication instead of the token. If the client you're writing is javascript that lives on the same server, you can simply pass the "useSession" parameter instead of the token, and javascript automatically passes the appropriate cookie. Java applets do the same thing. If your client is something else, you could store and pass the cookie manually.</div>
<div><br></div><div>I will work on fixing this bug for now. Thanks for the report.</div><div><br><div class="gmail_quote">On Mon, Jul 2, 2012 at 8:36 PM, Mona Wong <span dir="ltr"><<a href="mailto:mona@sdsc.edu" target="_blank">mona@sdsc.edu</a>></span> wrote:<br>
