Your Regular Expression Extractor
configuration should be like:
Reference name: Courselectureid (Could be anything)
Regular Expression: "courselectureid":(\d+)
Template: $1$
Match No.(0 For Random): 1
For Regex test see here: https://regex101.com/r/MdHaYq/1
Here, the total number of match found will be 4, but you need to extract only one of the values 1429
. That's why Match No.(0 For Random): 1
is used. You could use the value 0
, in that case, it will pick a match randomly. In you case, it will not have any impact as all the matches are returning the same value 1429
.
