In a thread i am producing a access token and want to use it in http header which is inside a loop, but in the http header i am getting a blank value
My test plan is like
TestPlan
ThreadGroup
Http header manager
token ${token}
http GET request to pull token from server
Json extractor to extract token from response as ${token}
loop for 100
http GET request
JSR223 preprocessor to give search parameters and corresponding values to get request
Listener tree results
Most probably your JSON Extractor fails somewhere as given your setup:
If you don't set the token variable - you will see the header as ${token} in the View Results Tree listener
If you set the token variable - the token header will have the variable's value:
So I would recommend adding a Debug Sampler somewhere after http GET request to pull token from server and double check that your token variable really has the anticipated value:
It must be any of your config issue or typo error. Below is sample setup which perfectly works for my project (Note: url & data has been mocked), see if this setup helps to resolve your issue. I am using JMeter 5.0 version :

In POSTMAN when i POST a URL with Headers with Body data it is working fine and getting Response as 200,but when i POST the same in J meter HTTP API request i am receiving the following Error.
Headers size in bytes: 124
Body size in bytes: 54
Sample Count: 1
Error Count: 1
Data type ("text"|"bin"|""): text
Response code: 404
Response message: Resource Not Found
If you're sending the same requests you should be getting the same responses. HTTP Status Code 404 means that URL path is not correct so you need to check the path of your URL as most probably there is a difference there. Even non-printable characters which you cannot see in JMeter GUI are encoded into their equivalents so whitespace becomes %20 so pay attention to literally everything.
In any case given you can successfully execute the request in Postman it means that you can record it using JMeter's HTTP(S) Test Script Recorder
Prepare JMeter for recording, the easiest way is using JMeter Templates Feature
once JMeter creates a Test Plan for your - expand and start the HTTP(S) Test Script Recorder
Prepare Postman for recording, configure it to use JMeter as the proxy:
Run your request in Postman
That's it, JMeter should capture the request and save it under the Recording Controller along with the HTTP Header Manager containing corresponding request headers
I am trying to carry out a test as like it explained here:
JMeter Alter HTTP Headers During Test.
Quote from above :
I'm attempting to test an HTTP service with JMeter. The HTTP service requires authentication through a simple bearer token mechanism. I'm trying to proceed as follows:
POST authentication request Store token as a variable
Set Authorization HTTP header to stored variable
Request protected resource(s)
Evaluate performance
When the POST occurs, I am not able to capture the bearer token. Its a header.
I tried the solution provided by Dmitri on that issue Or as Bennet tried with RegEx Extractor and HTTPs Manager.
I think I am doing something silly not to able to extract the token. Any thoughts how to extract the token?
Most likely your Regular Expression Extractor configuration is not correct, by default it:
uses response body as a source therefore you need to switch it to look into response headers (red rectangle)
looks up in main sample only, if your header is set after redirect it won't be processed (amber rectangle)
Example configuration:
You can double check ${bearer} variable value using Debug Sampler and View Results Tree listener combination.
I have internal web application, which I have to test using Jmeter.
The application has secure protections as a username, password and auth token.
Auth token is changing with every new session. I'm unable to path through secure token. Token is include in URL, which look like
http://mytraining.application.net/(S(vj1ckr0nqyvjq3blehcl2jwl))/ApplDefault.aspx?tabid=1. Cookies has look like
Cookie: AUTH_TOK_vj1ckr0nqyvjq3blehcl2jwl=vj1ckr0nqyvjq3blehcl2jwl; AUTH_TOK_syq3r1yu4equ515xzunjobhb=syq3r1yu4equ515xzunjobhb;
So, my Jmeter able to successfully run only when I submit current token in URL.
Please let me know if you have any idea, how to avoid submitting token in all places (35) every time.

My AUTH_TOKEN
Regular Expression
It seems you can figure you your Auth_TOK value from the cookies
Add the next line to user.properties file (located in JMeter's "bin" folder
CookieManager.save.cookies=true
Restart JMeter to pick the property up
Add HTTP Cookie Manager to your Test Plan
Now you should be able to see Cookies stored as JMeter Variables using Debug Sampler and View Results Tree listener combination and use cookies values as part of your URL
I would also recommend checking out ASP.NET Login Testing with JMeter as my expectation is that you will have to deal with few other dynamic parameters.
First try with HTTP Cookie Manager as mentioned by Dmitri. This would work if auth token is used in Headers, like Cookie header. Jmeter automatically fetches from Set-Cookie Header, set by server, (when you add HTTP Cookie Manager) for each thread and store it locally, so that it can use in subsequent requests.
If Auth token is used in other places (but not headers) such as part of Url, request body etc, then we should explicitly capture it using Regular Expression Extractor (post processor) and
Regular Expressions Jmeter to correlate the dynamic values. Once you capture the value into a local_variable, we replace the actual values by local_variable (Reference name field in Regular Expression Extractor) wherever we observe the dynamic value in subsequent requests, here auth token, using syntax ${local_variable}.
I am a bit of a newbie to Gerrit customization and running tests against Gerrit server.
In 2.4 version of Gerrit, an http login request (in my case from python file) would return a result that had the xsrfToken field and value as members of gerrit_hostpagedata (e.g. in request result you would see gerrit_hostpagedata.xsrfToken=<some value>).
In 2.8, this has changed so that xGerritAuth is now the field for the token value. However, the response from the server to my http login request (via python) is not returning the xGerritAuth field/value pair.
In the web UI for Gerrit, if I view the source when logging in, I can see the xGerritAuth field/value pair.
So I am wondering is there a way to get the xGerritAuth value returned in the response to the http login request?
NOTE that the gerrit/common/data/HosptPageData.java has changed to reflect the new token name (xGerritAuth).
thx

You need to parse the xGerritAuth out of the HTML response (which you get when you send your credentials to /login/). I do exactly that in my gerrit-rest-java-client. Check out this code. (tryGerritHttpAuth and extractGerritAuth).
Another way: use the (new) REST API of Gerrit. There you can use the HTTP credential you set in your Gerrit account settings. See REST API’s documentation.
I have implemented CSRF (corss site request forgery) in login page of my application.
when i try to do load test using apache jmeter, i am getting (login time exceeded) error.
if i create custom debug.jar to remove csrf it is working fine.
it is getting very tedious for each time to load the debug.jar while doing load test.
I am new to jmeter can any one help me out with this.
Thanks.
CSRF usually results in mandatory either header or cookie which needs to exist elsewise the request won't be served. CSRF token usually lives in every response so it's "classic" correlation example. So the flow should look as follows:
GET first page
Extract CSRF token using one of the following:
Regular Expression Extractor
CSS/JQuery Extractor
XPath Extractor
GET next page
Send CSRF header or cookie using
HTTP Cookie Manager
HTTP Header Manager
These "managers" should be added as a child of "next" request.
