Alfresco REST Core API retrive Version by node-uuid


I am developing an Alfresco client based on REST APIs.

But I haven't found a method that allows to retrieve a version with its node-uuid without knowing its parent UUID

[ base url: /alfresco/api/-default-/public/alfresco/versions/1 , api version: 1 ]

Solution

  • Below Rest api retrieve the version history for the file without knowing parent uuid.

    http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/{{fileId}}/versions

    This one will provide the exact information's of version 1.0, same way you can retrieve all the versions. http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/695b8a62-b566-4d49-9a4f-8f509f8cae59/versions/1.0

                }
            ]
        }
    }
    

    The below code Return version history as a paged list of version node infos.

    @Override
    public CollectionWithPagingInfo<Node> readAll(String nodeId, Parameters parameters)
    {
        NodeRef nodeRef = nodes.validateOrLookupNode(nodeId, null);
    
        VersionHistory vh = versionService.getVersionHistory(nodeRef);
    
        Map<String, UserInfo> mapUserInfo = new HashMap<>(10);
        List<String> includeParam = parameters.getInclude();
        
        List<Node> collection = null;
        if (vh != null)
        {
            collection = new ArrayList<>(vh.getAllVersions().size());
            for (Version v : vh.getAllVersions())
            {
                Node node = nodes.getFolderOrDocument(v.getFrozenStateNodeRef(), null, null, includeParam, mapUserInfo);
                mapVersionInfo(v, node);
                collection.add(node);
            }
        }
        
        return listPage(collection, parameters.getPaging());
    }
