Error retrieving data from post request

QazWsxEdc190721 — Tue, 27 Jul 2021 09:39:35 GMT

You need to create a new folder. An error occurs when extracting parameters from the post request.

public class WebScriptPost extends DeclarativeWebScript{
    @Autowired
    private NodeService nodeService;
    @Autowired
    private Repository repository;

    public final void setNodeService(final NodeService nodeService) {
        this.nodeService = nodeService;
    }
    protected Map<String, Object> executeImpl(WebScriptRequest req,
                                              Status status) {
        Map<String, Object> model = new HashMap<String, Object>();
        String path = (String) req.getParameter("path");
        String newFolderName = (String) req.getParameter("newFolderName");
        System.out.println(path);
        System.out.println(newFolderName);
        model.put("path", path);
        model.put("newFolderName", newFolderName);
        NodeRef nodeRef = repository.findNodeRef("path", path.split("/"));
        NodeRef newDocumentNodeRef = nodeService.createNode(nodeRef,
                ContentModel.ASSOC_CONTAINS,
                QName.createQName(NamespaceService.CONTENT_MODEL_1_0_URI, newFolderName),
                LmrContentModel.getQName("cm:folder")
        ).getChildRef();

        return model;
    }
}

You seems to be getting the error at this method call: "findNodeRef", the path needs to be qname. else system thinks you are just passing the qname but not localname. In general a path looks like (QName:localname):

"/cm:SX/cm:Administration/cm:Dictionaries/cm:General"

Unrelated to the error, but seems you are also passing json in post request as well as in the request param. You should use either one of the two. It doesn't make sense to pass param and also pass json body. Its better to just use the json body in the request. To extract the json from request body use this approach:

 final JSONObject requestPayload = new JSONObject(request.getContent().getContent());

The better way to create path based folders is to use TMDQ, and create the folders/subfolders based on path. Checkout this solution:
