Get and set access token through Jmeter

I am new in JMeter. I am trying to set access token dynamically through "Regular Expression Extractor". Basically I am trying to first login and then from it's response , I am trying to get access token and set it in "CreatePost" API.

I am able to get access token using #1 Login API where response is as below.

{ "Message": "Login successfully.", "Status": "Success", "HttpStatus": 200, "Data": { "token_type": "Bearer", "expires_in": 10000, "access_token": "eyJ0eXAiE", "refresh_token": "2bcf1f455f2", "name": "jmeter_test", } }

Could you please help me to get access_token from above response. To get this , I have created "Regular Expression Extractor " and set 

Name of Createdvariable :  access_token,
Regular Expression:        "access_token": "value"
Template                   $1$
Match No.                  1

Could yo please check the regular expression?

Thanks in advance.

Solution

  • If you really need to use the regular expression extractor you need to amend your regular expression to look like:

    "access_token":\s+"(\w+)"

    However for JSON responses it makes sense to use JSON Extractor which allows executing arbitrary JsonPath queries to get "interesting" data from the JSON responses, the relevant JsonPath expression will be:

    $..access_token
