I am having a hard time get the "Regex Expression Extractor" working in Jmeter for the following:
Response Header is something like:
Set-Cookie: Token=dfrtydgsdttetert; Domain=.domain.ca; Path=/;
Expires=Fri, 19 Oct 2018 18:54:18 GMT; Secure
ETag: W/"41c-gdf+/mzdw"
In JMeter Regular Expression Extractor:
Apply to: main sample and sub-samples
Field to check "Response Header"
Name of create Variable: extracted_token
Regular Expression: (?<=Token=)(.*)(?=; Domain) <- the goal is
the get the string "dfrtydgsdttetert"
Template: $1$
Match No: 1
Default Value: ERROR
I tried the above configuration and the extracted_token variable is always "ERROR"
if I change the regex to Token=
then I get:
extracted_id_token=null
extracted_id_token_g=0
extracted_id_token_g0=Token=
Please guide me how to fix my configuration so I can retrieve "dfrtydgsdttetert" in the response header.
To do this extraction the most performing way is to use Boundary Extractor:
If you still want Regular Expression Extractor:
The "response header" you're trying to extract is basically a HTTP Cookie, JMeter automatically handles cookies via HTTP Cookie Manager so you can just add it to your Test Plan and it will be way more convenient than manually extracting the values from the Set-Cookie header and adding them to Cookie header.
If you need the cookie value for other reason you can get it from the HTTP Cookie Manager itself
Add the next line to user.properties file (lives in "bin" folder of your JMeter installation)
CookieManager.save.cookies=true
Restart JMeter to pick the property up (the change will be permanent)
Add HTTP Cookie Manager to your Test Plan
That's it, now you will be able to refer your Token cookie value as ${COOKIE_Token} where required, no need to extract it from the header.

I am now using Jmeter to prepare a test plan for my web. The rough flow of the script is that I can check my profile after login. I tried to run my recorded script, and found that the cookie is encoded in http format which I don't want it to be.
Therefore, I would like to ask is there anyway so that I can have a not encrypted cookie value?
[I applied a cookie manager in the script.
The value of the cookie now is something like "%22mh8eIAH8rfsZsM3r%22".
The value that I want is something like "mh8eIAH8rfsZsM3r"]
%22 means " which is percent-encoded, if you want to decode it back - take a look at __urldecode() function:
In general you should not be recording any cookies, you need to add a HTTP Cookie Manager and JMeter will automatically extract incoming cookies from Set-Cookie response header and add them to the next request as Cookie header if domain and path match the ones in the cookie, it's not expired, etc
If you need to access the cookie value as a JMeter Variable the easiest way is adding the next line to user.properties file:
CookieManager.save.cookies=true
and upon JMeter restart you will be able to use the cookie value as ${COOKIE_your-cookie-name-here}

I am using a JSR 223 preprocessor to generate cookie from a text file and it works just fine. However, this cookie gets duplicated on every HTTP sampler request i have.
How can i avoid this ?
My testplan structure is :
testplan
-CookieManger
--testFragment
---JSR223 PreProcessor
----Transaction controller
-----HTTP request1
-----HTTP request2
-----HTTP request3
-----HTTP request4
in the first http request the cookie appear just once, however on HTTP request 2,3,4 the cookie is duplicated 2,3,4 times even though i checked the "clear cookie each itteration" in the cookie manager. How can i avoid this ?
Please note i'm a beginner to jmeter
Be aware of JMeter Scoping Rules, given the current placement of the JSR223 PreProcessor it will be executed before every HTTP Request sampler.
The easiest workaround is just moving it to be a child of the HTTP Request 1
Alternatively you can check the presence of cookie and add it only if it's absent, something like:
if (sampler.getCookieManager().getCookies().find { cookie -> cookie.getName().equals('your-cookie-name-here') } != null) {
//the code to add cookie from the text file here
}

How to extract a token value which is available only in Inspect elements-> Application (Not in Inspect Elements-> Network) thru Jmeter?
The access token value is available in the response headers. You can use a post-processor element to extract the access token from the header.
Here is an example to extract the access token using a Regular Expression Extractor Post-processor
It comes as a Cookie so the easiest way to extract it is to:
Add HTTP Cookie manager to your Test Plan
Add the next line to user.properties file (lives in "bin" folder of your JMeter installation)
CookieManager.save.cookies=true
Restart JMeter to pick the change from point 2
Once done you should be able to access the token as ${COOKIE_accesstoken} where required

On Jmeter: View Result tree: Request: Raw
Cookie Data:
.ASPXAUTH=EBB383A4DA12F0C106F044F70EC6CD6637252490DA31179407C466B8933D8B32622584F7A9F18A40C9D423078313E6ACB89519497CDDED451AF0C857AF3D6ED1C12296E56CE7D6058D7450E74B845EE39F3404925F679F180493329BDA021698
Regular expression extractor
Main Sampler Only
Request Headers
Regular Expression : Cookie Data:(.*)
Template : $1$
Match No : 1
Still getting Null Value
Also tryed with
Cookie Data:\n(.*)
Please Suggest.
Given the value is stored in the HTTP Cookie Manager, you can access it using below steps:
Add CookieManager.save.cookies=true line to user.properties file
Restart JMeter to pick the property up
Access the cookie value as ${COOKIE_.ASPXAUTH} where required.
See Using the HTTP Cookie Manager in JMeter article for more detailed explanation of the above steps
In Regular Expression Extractor, under Field to check, please select Response Headers radio button.
To save Cookies automatically, In jmeter.properties file, set as following:
CookieManager.save.cookies=true
Restart Jmeter.
You can access the saved cookies with COOKIE prefix.
example (in your case):
${COOKIE_Cookie_Data} # confirm the same in debug sampler result in View Results Tree
I strongly suggest adding Debug Sampler & View Results Tree, which shows the saved cookie values.
Try "Cookie Data:\n(.+)" as your regex.
= Anything In ()
= At least one character in ()
I want to do a load test my Heroku application using Jmeter.
To access the functionality of the application, I need to login through Facebook first.
I tried with browser recording using proxy server. But the problem is the code parameter (response_type) returned by facebook is hard coded in the callback URI. So its giving exception (Code expired exception) while running the Jmeter script.
I am able to view the code in response header of https://www.facebook.com/dialog/permissions.request URL. So I need to grab this code from this header dynamically and put in the code parameter of callback URL.
For this I am using Regular Expression Extractor in Jmeter under /dialog/permissions.request URL.
My response header looks like below:
Cache-Control private, no-cache, no-store, must-revalidate
Date Wed, 26 Dec 2012 13:37:17 GMT
Expires Sat, 01 Jan 2000 00:00:00 GMT
Location http://myapplication.herokuapp.com/oauth/authenticate/facebook?code=SOME-CODE
P3P CP="Facebook does not have a P3P policy. Learn why here: http://fb.me/p3p"
I want to extract this code=some code and put it in the next URL using regular expression extractor.
I don't know the JMeter context, but the regex can be something like:
\?code=(.*)
You might need to double the backslash. The $ can be problematic if the header is checked as a whole, you can replace it with \n perhaps.
[EDIT] I found the tester pointed from the JMeter page and used it against the header content you gave. Apparently the $ was not necessary, the search is stopping on a line bound. Still not sure about doubling the backslash. Experiment.
Problem is not with Regular Expression Extractor as mentioned by Saswat Sahoo. Main problem is Location header not even getting in Response header of Jmeter. We can see Location header in Browser's response header. Few information are missing in Jmeter Response Header compared to Browser's response header.
