[Web Service] Way to retrieve Alfresco Groups ?

[aragorn185]

How do you retrieve all groups where a specific user belongs using Alfresco Web Services ?

[openpj]

In the following snippet you can get all the authorities for a user:

WebServiceFactory.getAuthorityService().getAuthoritiesForUser(userName);
‍‍‍

Then you can filter all the values that start with the GROUP_ prefix to identify all the groups.

Hope this helps.

Thanks OpenPj for your response but i do not have a reference to AuthorityService.
The list of available webservices is:

• AuthenticationService


• RepositoryService


• ContentService


• AuthoringService


• ClassificationService


• ActionService


• AccessControlService


• AdministrationService


• DictionaryService

So i wonder how to retrieve a reference to AuthorityService ?

I'm sorry, you're right!  :roll:

For solving this feature you can implement your own custom WebScript (Custom Action) to search all user groups, then you can call it from your web service and you can return values from WebScript to your Web Service.

WebScript code:

serviceRegistry.getAuthorityService().getAuthoritiesForUser(userName);
‍‍‍

Web Service code:

Action userGroupsAction = new Action();
userGroupsAction.setActionName("userGroupsAction");
userGroupsAction.setParameters(properties);
ActionExecutionResult[] results = WebServiceFactory.getActionService().executeActions(predicate, new Action[]{userGroupsAction});
‍‍‍‍‍‍

                 
You can see this pages from the wiki for more details:

Hope this helps.

Hello,

I have implemented this custom action and in the class, Ihave this code :

@Override
   protected void executeImpl(Action action, NodeRef nodeRef) {
      userName = action.getParameterValue(Constants.PARAM_USER_NAME).toString();
      System.out.println("Search groups of user : " + userName);
      
      Set<String> groups = serviceRegistry.getAuthorityService().getAuthoritiesForUser(userName);
      
      String strgroups = "";
      int i = 0;
      for ( String str : groups ){
         if ( i>0 )
            strgroups += ",";
         
         strgroups += str;
         i++;
      }
      
      action.setParameterValue(Constants.PARAM_USER_GROUPS, strgroups);
      System.out.println("Groups of user : " + strgroups);
   }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And when i call this action using webservice:

ActionServiceSoapBindingStub actionService = WebServiceFactory.getActionService();
Action action = new Action();
NamedValue nv = new NamedValue();
nv.setName(Constants.PARAM_USER_NAME);
nv.setValue("neil");
action.setActionName("userGroupsAction");
action.setParameters(new NamedValue[]{nv});
ActionExecutionResult[] results = actionService.executeActions(prd, new Action[]{action});
‍‍‍‍‍‍‍‍‍‍

there is no Constants.PARAM_USER_GROUPS parameter in the results !
The action execute correctly.

Any Idea ?

[openpj]

Are you sure that you are calling exactly the same parameter?
I suggest you to recheck your code, look at what you have setted as parameter in the action and what you are calling from web service  :wink:

Hope this helps.

FYI, although web scripts are the way to go, with Alfresco 3.x you also have the option to use the updated AccessControlService:

It doesn't work! I tried to use "PROP_USERNAME" instead of "PARAM_USER_NAME" to search "GROUP_EVERYONE", which must exists, like this:

NamedValue nv = new NamedValue();
nv.setName(Constants.PROP_USERNAME);
nv.setValue("GROUP_EVERYONE");

Action userGroupsAction = new Action();
userGroupsAction.setActionName("userGroupsAction");
userGroupsAction.setParameters(new NamedValue[]{nv});

ActionExecutionResult[] results = WebServiceFactory.getActionService().executeActions(predicate, new Action[]{userGroupsAction});
‍‍‍‍‍‍‍‍‍‍‍

I still got AxisFault exception. The exception message is: "No bean named 'userGroupsAction' is defined"
