How to extract complete JSON response data in JMeter?

Question

I am new to JMeter and still in learning phase.

I am making a rest call in JMeter. The response data that i receive, i want to use it as it is in following rest call. Sample of response data that i receive is:

{  
   "token":"ab062ad1-0585-4b41-b491-1bd4f6de57da",
   "refreshToken":"5444b837-7f18-4570-a84b-80dac80b393c",
   "expiresBy":"Sat May 02 14:49:06 EDT 2015",
   "mcomroles":[  
      "Super BA Admin",
      "WorkgroupSuperBAUser"
   ],
   "bcomroles":[  
      "Super BA Admin",
      "WorkgroupSuperBAUser"
   ]
}

For this i added a Regular Expression Extractor but i do not know what regular expression to give.

Please suggest. Thanks.

Answer 1

If you want to use response as it is , add a beanshell-post processor instead of Regular Expression Extractor.

vars.put("JSONResponse", prev.getResponseDataAsString());

Now you access it using below statement in the next request.

${JSONResponse}

Answer 2

You can use Regular Expression Extractor to get the whole response and save it to a JMeter Variable.

As per How to Extract Data From Files With JMeter guide the regular expression which will match everything looks as

(?s)(^.*)

The whole extractor configuration should look like:

${response} variable will hold parent sampler response data.
