Accessing WCM Content through Web Scripts

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hi,
I am a newbie to alfresco. I have created a sample wcm project and want to create a web script that will return me the contents of a specified file.
I saw an example in the forum for the same that returned the contents of a file in Guest Home. Now when i try to access the files in my web project i can either
1) Traverse the node via the path.
The script for that I used for accessing the file Guest Home directory is :

var data = companyhome.childByNamePath("/Guest Home/a.xml");
if(data == null ){
logger.log("No files found");
      status.code = 404;
      status.message = "No files found";
      status.redirect = true;
} else {

model.storeid = data.getId();
   model.dataRetrieved = data;
}
‍‍‍‍‍‍‍‍‍‍‍‍‍

2)The second way could be performing a lucene search for the ID of that file.
The code for the same is:

var files = search.luceneSearch("ID:\"workspace://SpacesStore/0d18339a-1c6e-4b92-975f-1d9004e96264\"");

if (files == null || files.length == 0) {
      logger.log("No files found");
      status.code = 404;
      status.message = "No files found";
      status.redirect = true;
} else {
          var data = files[0];
          model.storeid = data.getId();
   model.dataRetrieved = data;
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Now both the codes work fine for the file in the guest home directory.
But when i try to perform a lucene search for a file in my wcm directory (again with the help of its storeid), it gives me no file found and i have no idea how to get the name path for that particular file!!!!!
Please help!!!!!!!!

Hi himanshu,

Content stored in WCM is stored in a different type of repository (AVM) so you have to access it differently.

Code like this below has worked for us:

script: {
   var store="youwebapp–sandboxname";
   var contentPath ="/www/avm_webapps/ROOT/path/to/your/content";
   if (storeExists(store)) {   
      var node = avm.lookupNode(store + ":" + contentPath);
           if (node == null) {
              status.code = 404;
         status.message = store + " could not be found.";
         status.redirect = true;
         return;
           }
           model.data = node;
   }
}

function storeExists(store){
   var storeRoot = avm.lookupStore(store);
   if (storeRoot == null){
      status.code = 404;
      status.message = store + " could not be found.";
      status.redirect = true;
      return false;
   }   
   return true;
}
