Unable to correlate session id using 'Regular Expression Extractor' in Jmeter
Steps
1.Recorded a UI through Blazemeter tool and opened that jmx file in Jmeter.
2.Added View Result Tree
3.Execute the script
Now session id is getting displayed in 'http request sampler',but not able to correlate it using 'Regular Expression Extractor'
https://xxxxxx.jsp?sid=00D1D0000008cuo%21AREAQGjkXGsXgyrRwsAnN2O0m0oiecGwTUd1n5zFPMIRRQVnu2RZnynMF5eTBhAzGRsQnWIzcdapD4GCysXbOA6JtSRi69Pq&apv=1&allp=1&cshc=D000000FAHdD0000008cuo&display=page
If you need to perform the correlation of this value: sid=00D1D0000008cuo%21AREAQGjkXGsXgyrRwsAnN2O0m0oiecGwTUd1n5zFPMIRRQVnu2RZnynMF5eTBhAzGRsQnWIzcdapD4GCysXbOA6JtSRi69Pq
You can do this using HTTP URL Re-writing Modifier, the only thing you will need to do is to provide sid as the "Session Argument Name"
If you want to use "classic" correlation using Regular Expression Extractor the relevant regex would be something like sid=(.+?)&
Demo:
Just make sure to apply the extractor to URL field:

I record my script from internet explorer using JMeter version 3.3 but when I run it the first HTTP request created a new session but the next request is nothing changed it is because the session id of the second request is indicated to its path unlike the first request.
So this is my question, How to use session id from the previous request and put it to the path in the second request. Please see the image below
Add Regular Expression Extractor as a child of the first request and configure it as follows:
Reference Name: anything meaningful, i.e. SessionId
Regular Expression: SessionId=([+-]?\d+)
Template: $1$
Replace hard-coded recorded value in 2nd request with ${SessionId}

What should be the Regular expression if I want to extract the value for access token, So that i can use it in Path of other Http request ie like access_token=93ee29b4-74dc-4uu7-8e10-6eac6845511b from below http response.
{
"access_token":"93ee2tum-1234-56789-8e10-6eac684551tum",
"token_type":"Bearer",
"expires_in":3600,
"scope":"test"
}
I have given regular expression as
"access_token":"([^"]+)"
And also where can i check the value of regular expression I am getting
You can test your Regular Expressions using View Results Tree listener in RegExp Tester mode like:
Also you can use Debug Sampler to see the associated JMeter Variables. See How to Debug your Apache JMeter Script article for details.
Starting from JMeter 3.0 it's more handy to use JSON Path PostProcessor, in that case the relevant JSON Path Expression would be as simple as:
$.access_token
You can add following regex. It will get the token and depending on the name variable you set, you can add one BeanShell Post-processor to print the token in console for you to verify. Just add the following to it:
log.info(vars.get("token"));
// token is the variable name which you specify in Regular Expression Extractor.
In jmeter: I’m using two http requests in one thread group, so I’m getting two response from those http requests.
I need ‘member id’ from one response and some string(digest) from other response, in order to create third http request.
I have extracted 'member id' by using this regular expression: {"Id":(.+?)}
which return me correct member id.
Response from 2nd request is string(digest) : "G9V6Su9PESaobcInErdD7Y8OKNo="
I added one more regular expression to extract this string : "(.+?)"
I have added two debug sampler as I'm using two regular expression extractor.
then I pass extracted values 'member id' and string(digest) as a parameter to third http request.
When I run it I'm getting error, my 3rd http request failed.
It's failing to pass extracted 'member ID', but its correctly pass string(digest)
In first debug sampler: its showing correct extracted 'Member ID' but some different values for digest field.
In 2nd debug sampler: its showing correct extracted 'digest' field but some different value for 'Member ID'.
I’m doing it all under one thread group
I'm new to jmeter, I don’t know whether it is possible to extract field from two different response and use as parameter to create new http request.
if it possible how to do it please help me.
Thanks in advance.
I believe that it's due to including quotation marks (and who knows what else) into the "Id" regular expression, you need to surround it with quotes like:
{"Id":"(.+?)"}
Also the better way of working with JSON data is JSON Path Extractor which is available via JMeter Plugins project. See Using the XPath Extractor in JMeter guide (scroll down to "Parsing JSON") for more information on installation, usage, syntax, etc.
Can somebody please explain me how can I use JMeter for Feature testing?
I'm able to create multiple HTTP requests within a Testplan. But I need know the way to capture the previous API response and pass one of the response data to the next API request.
Eg:
1.Create Account.
Request- POST: /account
Response: ID: "Value"
Read account
Request- GET: /account/
JMeter is really more of a load testing tool, and best used as such. Capturing data from responses is possible using the Regular Expression Extractor, which can store extracted values in variables for use in a subsequent request. It is a bit of a pain in the ass to use, though.
On your request, add a Regular Expression Extractor:
Field to check: body
Reference name: EXAMPLE
Regular Expression: \[.*\] #your regex here, stuff in square brackets as example
Match No.: 1
In a subsequent request, you can then use the variables defined by the extractor, e.g. ${EXAMPLE_g0} for the entire match, or ${EXAMPLE_g1} for group 1, etc.
I am testing a site using JMeter. I am creating a GET request for getting an account number by an unique id. Which returns only the account number(in String). How can I get the account number in to a Reference Name of JMeter extractor?
Use Regular Expression Extractor.
Add Regular expression extractor (under Post Processors) as a child of your request. Provide Reference Name of your choice. Provide Regular expression as (.+?).
As you say the response has only the Account Number you are looking for,
Use a Beanshell post processor,
vars.put("ACCOUNTNUMBER", prev.getResponseDataAsString());
Then you can use ${ACCOUNTNUMBER} , in your test to get the value.
