I want to put all the items of that were taken from a get api request in list format in Jmeter

Question

I have a get api and I want to get all the ID's that are present in it and put them in a list/array so I can use it in other api where I want to seperate even and odd elements from that list and pass it as a variables

The get api is something like https://api.abs.com/contents

From this api I have taken the ID's using json extractor and stored them in id variable name.

Now I want to put all id elements into a list/array and seprate them into odd and even number and store in 2 variables(if possible provide the code how to seprate them as well)so I can pass them into a post api in loop

How is this possible Is there any way in Jmeter to do this..please help me out

To do any sort of logic in JMeter, it's usually best to use a scripting sampler or pre/post-processor to implement a script with the logic. If you use a JSR223_Sampler, you can import or run a Groovy script.

For example your Groovy code to get the even or odd values and store them in a JMeter variable might look something like this:

// Get JMeter variables
def allValues = vars.get("valuesVariable")
def values = allValues.split(",")

// Apply groovy logic
def evenValues = values.findAll({ i -> (i as int) % 2 == 0 })
def oddValues  = values.findAll({ i -> (i as int) % 2 != 0 })

// Save as JMeter variables
vars.put("evenVariable", evenValues)
vars.put("oddVariable",  oddValues )
