How to use object.find on nested Value

i have an object in grovvy with a list of key:value pairs. I'm using this code to extract only the matrix value for this Object.

Object :

[{"id":null,"dimension":"f7f04751-5ac9-4867-a742-6f69a53d99d3","matrix_value":"ac726cd4-0aaf-4b4b-91c1-bceda8dded04","name":"Linear","include":false,"children":[{"id":null,"dimension":"f7f04751-5ac9-4867-a742-6f69a53d99d3","matrix_value":"efc05bdb-ebc8-4167-85fb-9e5a63a1200b","name":"Little Linear","include":false,"children":[]}]},{"id":null,"dimension":"f7f04751-5ac9-4867-a742-6f69a53d99d3","matrix_value":"a2b932d3-14f0-480f-8eeb-d1fc00a1c7ab","name":"Not Linear","include":false,"children":[]}]

I know that with it.name i search only at the top level values of the object. How can i modify this code to check if the field children is not null and in that case apply the find also to the child element and extract the matrix_valiue? Thank you.

import groovy.json.JsonSlurper;


def Dimensions = vars.getObject("Dimensions")



String[] DimensionKeyset = vars.getObject("DimensionKeySet");
String Dimension_name = DimensionKeyset[Integer.parseInt(vars.get("ContoDimensions"))]
String[] Values = Dimensions.get(Dimension_name)
def Body = vars.get("Body_Get")
def jsonSlurper = new JsonSlurper();
def list = jsonSlurper.parseText(Body);
def rc_dimension_values = []
log.info("La lista è: "+ list.toString())

log.info("La vera lista è: "+ list.getClass())


for(v : Values) {
    
    rc_dimension_values += list.find { it.name.trim() == v.trim() }.matrix_value
     log.info("L'oggetto è:" + list.find { it.name.trim() == v.trim() } )
    log.info("Check For Values: " + v)

    
    
}

def builder = new groovy.json.JsonBuilder(rc_dimension_values)

vars.put("rc_dimension_values", builder.toString());
Solution

  • If you just want to get all matrix_value wherever they are the easiest would be switching to JSON Extractor. If you use deep scan operator like:

    $..matrix_value

    it will store all the values to the JMeter Variables:

    If you want to stay with Groovy you can use the following code snippet which uses the same JsonPath library which is under the hood of the JSON Extractor:

    vars.put('rc_dimension_values',new groovy.json.JsonBuilder(com.jayway.jsonpath.JsonPath.read(prev.getResponseDataAsString(),'$..matrix_value')).toPrettyString())

    it will generate a JSON Array from the found matrix_value attributes and store it into rc_dimension_values variable:
