Jmeter- How to Extract part of the API Response value using Jmeter?

Question

I have the below response from the API:

{"info":{"message":"success","details":{}},"data":"https://127.0.0.1:80/view-report?https://routethis.creativeadvtech.ml/api/v1/report/get_subscriber_report?verification_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJ2aWV3X3JlcG9ydF90b2tlbiIsImlhdCI6MTY0NDQyNzEzNSwibmJmIjoxNjQ0NDI3MTM1LCJqdGkiOiJhOTFlZWY0Ny01ZWY1LTQ3YWEtYTc0Ny1mYTNhOWM4MWRmNjMiLCJ0eXBlIjoiYWNjZXNzIiwiZnJlc2giOmZhbHNlLCJyZXBvcnRfaWQiOiI1YzQxYzU4MC04OWNjLTExZWMtOWM4Zi1hNjkzNGQ4NWQxMDkiLCJjdXN0b21lcl9pZCI6ImY2MGIyMjc0LWQ2MTAtNDBkMS1iNjJjLTc5NTEwOWZjMjk0ZiJ9.ica2CS-cT3RxbNPhMUn1Tw_HGtODmgAzS_JpjoS22NU"}

Question: How to extract the Verification_token value only notice that the whole data response is a full value attached to each other?

Answer 1

Your regular expression extracts the whole contents of data attribute, why would you expect it to return the partial value.

If you need the token only - you need to amend your regular expression to something like:

{"info":{"message":"success","details":{}},"data":".*verification_token=(.+?)"}
