Passing a variable from a response to a request in JMETER

Question

It is necessary to transfer data from the response to a subsequent request. Something is wrong, and the default value of the variable appears in the request.

Answer 1

There is a JSON Path Extractor designed to work with the JSON content type, I believe it would be easier to use it.

JSON Path , $..id

. XPath Extractor JMeter ( "Parsing JSON" ) JSONPath - XPath JSON JSONPath .

Regular Expression Extractor:

• 1
• $1$

Answer 2

, . $1 $ .

Answer 3

The problem was resolved by setting the Check Field switch to Body in the Regular Expression Instance dialog box and setting the Pattern field to $ 1 $. Thanks alphamikevictor and Dmitri T for the help!
