Currently I am using regular expression extractor

token: "(.*?)"

Answer 1

Just add closing quotation mark to your regular expression as

token": "(.*?)"

and use $1$ as Template

Another option is using JSON Path Extractor which comes with JMeter Plugins which is more handy to extract stuff from JSON responses. In that case use the following JSON Path query:

$..token

See Using the XPath Extractor in JMeter guide (scroll down to "Parsing JSON") for more information on the JSON Path language and few useful examples.

Answer 2

Extracting token value from the response

So here I you used as User id so please change this in token so and use post processor regular expression it will definitely work

Answer 3

Use

"token":"(.+?)"

in the JSON Path Extractor.

Answer 4

In regular expression extractor use regular expression as token": "([^"]+)" and template $1$. I hope this will help you.
