getFolderTree and recursion

nverwer — Tue, 20 Mar 2012 13:25:08 GMT

(Alfresco community edition 4.0.0 b)I am trying to get a complete tree listing of a folder, and it looks like the CMIS api getFolderTree (http://wiki.alfresco.com/wiki/CMIS_Web_Scripts_Reference#Get_Folder_Hierarchy_.28getFolderTree.29) is the right way to go. However, this will only return one leve

Starting with Alfresco 4, the old web script-based CMIS implementation which you will be using if you use the old CMIS ATOM service URL (http://localhost:8080/alfresco/s/api/cmis) is deprecated. Instead, you should use the OpenCMIS-based implementation, which you get to by using this URL: http://localhost:8080/alfresco/cmisatom.

I just ran a quick test using cmislib against Alfresco 4.0.b Community and noticed that when I use the deprecated URL, I only get the first level on a getTree call. But when I use the new OpenCMIS-based URL, I get the full tree.

>>> client = CmisClient('http://localhost:8080/alfresco/cmisatom', 'admin', 'admin')
>>> repo = client.defaultRepository
>>> folder = repo.getObjectByPath('/test')
>>> tree = folder.getTree()
>>> for res in tree:
…     res.name
… 
u'sub1'
u'sub11'
u'sub111'
u'sub112'
u'sub12'
u'sub2'
u'sub3'
>>> client = CmisClient('http://localhost:8080/alfresco/s/api/cmis', 'admin', 'admin')
>>> repo = client.defaultRepository
>>> folder = repo.getObjectByPath('/test')
>>> tree = folder.getTree()
>>> for res in tree:
…     res.name
… 
u'sub2'
u'sub3'
u'sub1'‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

There are other differences between the two implementation as well, so please do use the new one if possible.

Thank you Jeff, this is very helpful information.
I do wonder if I could have known this. The services listing from Alfresco …/alfresco/service/ happily lists the deprecated CMIS services.

Best regards, Nico

There is a Jira to get those marked as deprecated. Looks like it is fixed in 4.0.1.
