Folks,I am trying to remotely retrieve content from an alfresco repository using a URL to the content in question.The URL is as follows:http://127.0.0.1:8080/alfresco/d/d/workspace/SpacesStore/57000863-5dbd-4153-9489-36f007a457d4/asampledocument.pdfThe client application is attempting to retrieve a

What I am trying to do here is authenticate and get data in a single http request. If I pre-authenticate, getting a "ticket" and then use the ticket in the subsequent request for the file, the interaction will work. Is there anyway to authenticate and request data in a single http request?

There is probably a nicer way to do this, but here is how I got the auth ticket:

<java>

      String name = "admin";
      String password = "admin";

      //First we need to pre-auth and get an authentication ticket
      String authURL = URL_PREFIX + "service/api/login?u=" + name + "&pw=" + password;

      ByteArrayOutputStream bais = null;
      InputStream is = null;
      byte[] xmlTicketByteArray = null;
      byte[] pdfAsByteArray = null;
      String xmlTicketString = null;
      String ticket = null;

      try {
         bais = new ByteArrayOutputStream();
         URL url = new URL(authURL);
         URLConnection urlConnection = url.openConnection();

         is = urlConnection.getInputStream();
         byte[] byteChunk = new byte[READ_CHUNK_SIZE];
         int n;

         while ((n = is.read(byteChunk)) > 0) {
            bais.write(byteChunk, 0, n);
         }

         xmlTicketByteArray = bais.toByteArray();
         xmlTicketString = new String(xmlTicketByteArray, "UTF-8");
      } catch (Throwable t) {
         logger.warn("Failed to retrieve PDF for URL " + aPdfURL, t);
         return pdfAsByteArray;
      }

      ticket = this.getAuthenticationTicket(xmlTicketString);

…

   /**
    * Parses out the authentication ticket from the XML.
    * @param anXMLAuthTicket
    * @return
    */
   private String getAuthenticationTicket(String anXMLAuthTicket){

      String extractPattern = "(?s)^.*?<ticket>(.*?)</ticket>";
      String authString = null;

      Matcher m = Pattern.compile(extractPattern).matcher(anXMLAuthTicket);

      if (m.find()) {
         authString = m.group(1);
      }
      return authString;
   }

</java>
