To be able to create a node, or update it, using the Alfresco REST API you will need to send the node’s properties in a JSON format along with the request.
If you are doing this programmatically in Groovy (let’s say, from an APS task script) you’ll find very useful the following code snippet.
/** * Gets node's properties in JSON format * @param type node content type * @param propertyMap node properties map * @param aspectList node aspect list * @return properties json object */ static String getPropertiesJson(String type, Map<String, String> propertyMap, List<String> aspectList) { def builder = new JsonBuilder() builder { name(propertyMap.get("cm:name")) nodeType(type) aspectNames(aspectList.collect { oneAspect -> oneAspect }) properties { propertyMap.each { key, value -> ["${key}"(value)] } } } println(builder.toPrettyString()) return builder.toString() }
