How to get noderef of file during file creation in share

hardik_thakkar

Hi Team,

I have requirement to restrict from creation of exe file.

User is creating plain text file from share UI and entering name like test.exe.

I have created rule that checks if file name ends with exe, it throws exception. But rule is not executing somehow.

Then i have created behaviour that executes on node creation, I am getting parentref using below code.

public void init() {
		policyComponent.bindClassBehaviour(NodeServicePolicies.BeforeCreateNodePolicy.QNAME,
				ContentModel.TYPE_CONTENT,
				new JavaBehaviour(this, "beforeCreateNode", Behaviour.NotificationFrequency.EVERY_EVENT));
	}
	
	@Override
	public void beforeCreateNode(NodeRef parentRef, QName assocTypeQName, QName assocQName, QName nodeTypeQName) {
		if (LOGGER.isDebugEnabled()) {
			LOGGER.debug("Started executing FileCreationRestrictionBehaviour ..");
			
			LOGGER.debug("parentref --> "+parentRef);
			
			LOGGER.debug("parentref NAME --> "+nodeService.getProperty(parentRef, ContentModel.PROP_NAME));
			
			System.out.println("parentref --> "+parentRef + 
					"parentref NAME --> "+nodeService.getProperty(parentRef, ContentModel.PROP_NAME));
			
			
		}
		
	}

So,my requirement is to restrict file creation, if users enters .exe in file name, how can i get the noderef/filename of that file, so, i can throw exception.

Thanks,
Hardik

Try : org.alfresco.repo.node.NodeServicePolicies.OnCreateNodePolicy

You can do something like this:

public void onCreateNode(final ChildAssociationRef childAssocRef) {
	final NodeRef nodeRef = childAssocRef.getChildRef();//node which is being created.
	if (nodeService.exists(nodeRef)) {
		final String fileName = (String) nodeService.getProperty(nodeRef, ContentModel.PROP_NAME);
		final String mimetype = mimetypeService.guessMimetype(fileName); //find mimetype by extension of the file.
		if (restrictedMimeList.contains(mimetype)) {// check whether the result is one of the restricted mime types from the list?
			throw new AlfrescoRuntimeException("Mimetype " + mimetype + " is unsupported");
		}
	}
}
