JMeter JSON Extractor, extract all values of one key in a string

Question

Using Apache JMeter ver 3.2 r1790745 (the latest) to test a JSON Web Service, the response is like:

[ {
   \"id\" : 3,
   \"description\" : \"Back\",
   \"na         


        

Answer 1

If you configure your JSON Extractor like:

You will get the required value as ${foo_ALL}

I don't think using Beanshell is the best way to check JMeter Variable value, going forward I would suggest using Debug Sampler instead, see How to Debug your Apache JMeter Script for more details.
