I am trying to write regular expression in JMeter regular extractor for CSRF Token:
CSRF Token: P_rF1DbLR4JWcBtxEwGKKw==
and Expression I am using is:
name : CSRF_Token_Retrieved_Value
regular expression: x-csrf-token:\s+(.+)
template : $1$
I get this error
CSRF token validation failed
in next steps.
Your regular expression doesn't match the value you provided, you need to change it to:
CSRF Token:\s+(.+)
Demo:
Also if the token comes in one of the HTTP response headers you need to switch the Regular Expression Extractor to look into Response Headers:

I've an isssue. I run a test plan in jmeter. I've a http request, response header has a URL with 1 parameter (Ex: response header => URL: http://abc.xyz?code=xxx). Now I want to get the value of parameter "code", and put it into the body of next http request. How can I do that? Please help. Sr if my English not good enough
If I'm correctly getting your requirement and you need to extract the code from a response header which looks like this:
You can do it using a Regular Expression Extractor configured like:

Request Verification Token is not identifying or getting assigned to a variable by JMeter for a new user registration
In GET, Request header - Request Verification Token is passed as Static one
In POST, Request header - Static request verification token is called and in PAYLOAD - Another dynamic Request Verification Token is displaying.
In POST url, I have used below Regular Expression Extractor:
Field to check: Request Headers
Name of created variable: Token
Regular Expression: input name="__RequestVerificationToken" type="hidden" value="([A-Za-z0-9+=/-_]+?)"
Template: $1$
Match no: 0
Queries:
Do I need to use Regular Expression Extractor in GET URL also, If yes what regular expression need to be used?
How to pass Static request verification token value in GET & POST URL?
Do we need to use 2 Regular Expression Extractor in GET & POST URL?
Could you please provide solution?
Field to check - needs to be Response Body
Using regular expressions for extracting data from HTML is not the best idea, consider switching to CSS Selector Extractor instead.
We don't know the answers to your questions because we're not familiar with the application you're testing, if you have doubts with regards to which values need to be correlated - record the same test scenario 2 times and compare the generated test plans. All parameters which differ are a subject to correlation.
In my JMeter script I have a request which uses a token as part of the request body:
I've got a regex extractor to retrieve this value but I can't seem to get it back. I've tested using all the "Field to check" values e.g. Request Header etc. The regext I'm using is "token=(.*?)"
This token is needed as other calls explicitly reference it and I need to pass them this variable
Switch "Field to check" to URL as in your case the token is not in the request body, it's in URL's Query String
Amend your regular expression to look like: token=(.*)
This way you will get the token value into the ${TOKEN} JMeter Variable.

Query parameters are part of the url, so choose URL as Field to check
Also you are building the URL, so can't you use save the token value before?
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.
I have to do performance testing for ipad application.
There is scenario in which i have to read the token id from the response and use this token id in my next request.
I used the regular expression extractor, but when i used the variable in next request i.e. ${tokenid}, it wasn't replaced with the captured value. When i look at View Result tree, it is simply requesting the variable instead of token.
Here is the regular expression extractor
There is at least an error where you must check:
Body
instead of checking :
Response Code
in Regular Expression Extractor
You can use View Result to check your regexp:
Finally regexp should be:
"Token":"([^"]+?)"
