JSON Path Extractor in JMeter

Question

I am new to jmeter. Can anyone help me to use a response object of one request to be passed as a request header of next HTTP request ?

Let me explain.

1. I am getting an access token along with the response of login in my app:

   {: "responseCode":18, : "message":"Successfully logged in.", : "responseObject":"8zWExE4eSdhcJDwnW9MgIw=="}

2. No I want to use this access token (8zWExE4eSdhcJDwnW9MgIw) as one of the parameter of next request.

I used JSON Path Extractor for this.But its not working.

Answer 1

I am using JSON Path Extractor as well and it works great if it is properly configured. Just put it into request and fill fields:

• Variable Name: access_token (or any other you want to use later in request like this ${access_token})
• JSON Path: responseObject should be enough if the JSON you pasted is full response (thjose additional colons are just some mistakes when copy-pasting or the JSON is corrupted?)
• Default Value: I always use some value like 'NotUpdated!' here so I can assert in the next step or at least see it easily in request.
