I am trying to capture csrf token and pass as a header in login request but encounter 403 error. I've checked the csrf token extracted from a previous request by using regex extractor and successfully passed as a header of login request. Do not know what the reasons why the login request is failed. Please kindly help.
Double check that you captured the value fully. Also using regular expressions for extracting values from HTML is not the best idea, maybe it worth considering switching to CSS Selector Extractor instead
It might be the case the token in the response is encoded somehow, i.e. URL-encoded or contains HTML escape characters or something like this so try using your browser developer tools to see the token in the response and in the header of the next request and compare them symbol-to-symbol
It might also be the case the CSRF token works fine and the problem is somewhere else, i.e. do you have HTTP Cookie Manager added to your Test Plan

I am getting below error in jmeter performance testing
ERROR:
The token in the request does not match the one in the session!
Scenarios:
user logs into the appln
click on the modify user from the menu
search for the user
select the user
adding roles to the user
6.click submit
7.click on return to search button.
8.click on logout.
I am getting the csrf token in the post method and i captured the csrf token in 2 samples before in the GET method.I added regular expression in GET method and i used that regular expression variable in the Post method token.
Please let me know how to fix the token error.
Thanks,
It's hard to provide a comprehensive response without seeing network dump of requests from the real browser and from JMeter, most probably you need to extract the CSRF token from every response, not "2 samples before", try moving your Regular Expression Extractor to the same level as HTTP Request samplers - this way it will be applied to all of them and will extract the "fresh" CSRF token from each response. See JMeter Scoping Rules - The Ultimate Guide article for more information
As per Cross-Site Request Forgery Prevention Cheat Sheet
The site then requires that every transaction request include this pseudorandom value as a hidden form value (or other request parameter/header)`
The following guidance will demonstrate how to create overrides in JavaScript libraries to have CSRF tokens included automatically with every AJAX request for the state changing methods mentioned above.
CSRF tokens should be generated on the server-side. They can be generated once per user session or for each request.
I am trying to do the load testing of salesforce.com. I am logging via test.salesforce.com which is redirecting me to the console url. Now, subsequent post request accepts following post parameters.
ViewStateCSRF
ViewStateMAC
visualforce.ViewState
But this post request is failing with "invalid session" error message.
I am guessing this is because of CSRF token. I am trying to extract(post processor in Jmeter) CSRF token, but I am unable to find this token anywhere in the response/cookie of previous requests. In one of the HTML response, I can find few CSRF tokens(e.g: runApexCsrfToken, consoleAjaxCsrfToken etc). I have tried all of them but no result.
To summarize my problem: I need to pass csrf token in post login request but I am unable to find this token in previous responses.
Could you please help me with this.
PS: I have tried get request on "https://c.salesforce.com/libs/granite/csrf/token.json" after login but did not find any token in response.
Make sure to add HTTP Cookie Manager to your Test Plan
Make sure to check all response fields as the token can be a part of URL or come as a HTTP Header
You need to correlate not only ViewStateCSRF but all other dynamic parameters as well
If you have problems with identifying the source for the dynamic parameters values you can try recording your scenario using cloud-based proxy service, it is capable of exporting recorded scripts in "SmartJMX" mode with automatic detection and correlation of dynamic parameters.

Does any one knows how to solve it with regular expression? here i am putting screen shot with valid access token and error response token.
thanks in advance.
Valid response token
invalid response token
and Regular expression exctracter
it is fine if you guys have any other solution for this unauthorized access thing.
Add JSON Extractor as a child of the authserver request and configure it as follows:
Variable Names: anything meaningful, i.e. token
JSON Path expressions: $.access_token
Add HTTP Header Manager as a child of the student request and configure it to send Authorization header with the value of Bearer ${token}
Going forward you can go for an alternative way of recording a JMeter test which is capable of exporting the recorded requests in SmartJMX mode with automatic correlation of dynamic parameters applied so you will be able to save your time for more creative work.

I'm having trouble with getting my site normally loaded during the performance testing in Apache JMeter. Firstly I recorded the script (by BadBoy), containing authorization and visiting some pages, unavailable without login. Next, I exported it to JMeter, configured Regular Expression Extractor to get the csrftoken from the request right before the authorization request and it looks like it works just fine:
no errors in http-requests
But if to look at the tab "Response data" of every post-authorized request, the content isn't like correctly loaded page, it just starts page with the empty authorization form, i.e. in some way session is new though all the requests have the same session id and csrftoken in Cookie Data and in Set-Cookie (Sample result), appeared in authorization request result.
HTTP Cookie Manager is added.
Did anyone face this trouble?
UPDATE: I've conducted an experiment with transferring cookies from Chrome to Mozilla Firefox, copied 'csrftoken' and 'session id', and - voila! - it worked, I got the same authorized session in two browsers. Still have no idea what's wrong with JMeter
JMeter automatically treats HTTP Response Codes below 400 as successful, it doesn't perform any checks of response body. Most likely your Regular Expression Extractor failed, add a Debug Sampler and double check resulting variable value.
There could be also the following possible reasons:
You might need to send CSRF token in encoded/escaped form so using i.e. __urlEncode() function will be required. Or vice versa.
Application may expect the token in multiple locations, i.e. not only as a form parameter, but as an extra HTTP Header. In that case you will need to pass it via HTTP Header Manager
You might also want to try the new step-by-step debugger for JMeter to get to the bottom of the issue.
This is the default behavior of this token. 1. make sure where these tokens are passed. It might be passed multiple times. Check the header. Generally, "xref-token" is again passed.
It should be in exact format, decode it if required, also remove , or ; or /. You can also use fiddler.
The solution was found after recording a script by Blazemeter plugin in Chrome and further exporting it in '.JMX' format. Adding an HTTP Header Manager like this (with its special fields, of course) to each HTTP Request solved the problem.
I m new in jmeter i want to know if i send post request for login with cookies then in Response below information is displaying .
Request Error We’re sorry, there was a problem with your request.
Please make sure you have cookies enabled and try again.
What could be going wrong.?
It may be not about the missing or incorrect cookies.
You need to provide valid loginCsrfParam value as well, it needs to be extracted from previous response via one of the following PostProcessors:
Regular Expression Extractor
XPath Extractor
CSS/JQuery Extractor
converted into a JMeter Variable and used as a parameter in your login request.
