I'm trying to extract the CSRF token so I can log in, and be able to obtain cookies, but I'm not able to.
I'm able to get a 200 response code when accessing the URL that contains the CSRF token, and I'm able to see it on the browser and the console, but my response assertion is not able to assert anything regardless of me changing the apply to, field to test, and pattern matching rules sections. My regular expression extractor isn't able to get anything either. All the headers to get to the URL are there. Any suggestions?
Forgot to mention, I'm able to get it on one server that's exactly (or should be) exactly the same as this one...
EDIT:
I placed it under the HTTP Sampler that has that response, and here is an example of what I get for my response assertion. I've also added various images.
Unfortunately you didn't share your output, so I cannot tell for sure, but although it seems your RegEx is correct in both cases, it could be that it doesn't match due to some extra spacing.
It appears that you are expecting a valid JSON, so instead of RegEx you could use JSON Extractor and/or JSON Assertion, for which extra spacing will not matter.
Example: if Response Data is
{"token":"12345"}
I can specify JSON Extractor as
(most important line is JSON Path: $.token)
and the result will be variable token with value 12345.
Here's a good online JSON Path tester, which can help you to figure out the right JSON Path.
If your goal is to check presence of a JSON Object with name of token and an arbitrary value I would recommend going for JSON Assertion instead.
Add JSON Assertion as a child of the request you would like to assert.
Use the following JSON Path query:
$.token
JSON Assertion is available since JMeter 4.0
If you still want to go for the Response Assertion - configure it as follows:
Pattern Matching Rules: Contains
Patterns to Test: {"token":"(.+?)"}

I can't extract the x-csrf-token and pass . I got error like csrf token expired [![enter image description here]
Anyone give some exact ans and support.
Your question doesn't contain sufficient level of details so it cannot be answered comprehensively.
First of all check your ${x} JMeter Variable value using Debug Sampler and View Results Tree listener combination
Then check the request header using the aforementioned View Results Tree listener. The token should be exactly the same as the one returned in the previous request.
Also it seems that your token comes in JSON-like structure, JSON is not a regular language so it would be a better idea considering using JSON Extractor instead of Regular Expression Extractor
I'm load testing my API which requires to authenticate everytime before calling the API. I need to read a query param from HTTP header "Location" and use it in further requests in Jmeter. I tried to use "Regular Expression Extractor" with Location: .+=(.*?)\n but it didn't work. Any ideas how to read a specific variable from response headers?
Location: https://<<SSO_URL>>/authenticate?code=AbCDEfg1&..... --> extract "code"
Please try with this, regex for your question is code=([^&]*)
You need to change your regular expression to something like:
Location:\s* .*=(.*?)&
And make sure to choose Response Headers from the scope:
See Regular Expressions chapter of the JMeter User Manual for more details
Also it might be much easier to use the Boundary Extractor, in this case you will just need to provide the "left" and "right" boundaries and it will fetch everything in-between:
Moreover it works faster and consumes less resources, see The Boundary Extractor vs. the Regular Expression Extractor in JMeter article for more information
New to JMeter, and I'm probably missing some simple thing but I can't find it anywhere.
I'm trying to log into a web application so I send a GET request to the home page to retrieve the csrf token and then I use the regular expression extractor to retrieve it:
I then try to place the extracted token into the POST request:
But the extracted token doesn't show up in the request sent via the View Results Tree. Only the UserId and Password are passed which I manually defined:
My regular expression is finding a match as you can see here:
but even if it wasn't finding a match, it should still pass "NotFound" correct?
Any help is greatly appreciated!
Edit: Added a Debug Sampler and it is correctly showing the variable Token with it's correct value. So Token just isn't being added to the request via the RegEx User Parameter Pre Processor.
It's difficult to see what you're doing without seeing the LoginPage step, but you need to make sure you are adding the csrf token you've extracted in the right place.
Typically it could be as a query param, part of a post body or an http header.
As you can see the token has been extracted from your initial response in the Debug sampler, there must be something wrong in how or where the token is being applied to the LoginPage request. (As you say the RegEx User Parameter Pre Processor isn't adding it)
I've never used the PreProcessor and the Jmeter documentation explanation is a bit vague on what it does, but you can add the variables into your request without it using the variable saved for the capture groups - for input name this will be ${Token_g1} and for value it will be ${Token_g2} - which you will be able to see from the Debug Sampler. You'll need to add a Header or Cookie Manager to the Login Page element if this is where the token is.
By setting the template in the Extractor to $1$$2$ you create a variable with the name and value concatenated together. I'm not sure why you would need this, and I would guess that the name doesn't change - in which case you can just use capture group 2, or if you want to use the Variable name Token then update your template to be $2$
I am new to jmeter. Can anyone help me to use a response object of one request to be passed as a request header of next HTTP request ?
Let me explain.
I am getting an access token along with the response of login in my app:
{: "responseCode":18, : "message":"Successfully logged in.", : "responseObject":"8zWExE4eSdhcJDwnW9MgIw=="}
No I want to use this access token (8zWExE4eSdhcJDwnW9MgIw) as one of the parameter of next request.
I used JSON Path Extractor for this.But its not working.
I am using JSON Path Extractor as well and it works great if it is properly configured.
Just put it into request and fill fields:
Variable Name: access_token (or any other you want to use later in request like this ${access_token})
JSON Path: responseObject should be enough if the JSON you pasted is full response (thjose additional colons are just some mistakes when copy-pasting or the JSON is corrupted?)
Default Value: I always use some value like 'NotUpdated!' here so I can assert in the next step or at least see it easily in request.
Not seeing the full response it is quote hard to come up with a correct JSON Path expression.
Given what you posted it should be something like $.responseObject
See JSON Path Syntax guide for queries syntax examples and Using the XPath Extractor in JMeter (scroll down to "Parsing JSON") for plugin installation instructions and XPath to JSON syntax mapping.
Just in case anybody would face an issue with multiple variable extractions using JSON Extractor (like me), make sure to:
List the names of variables/path expressions/default values using a semicolon as a separator.
Provide default values for every variable.
The second point is apparently required, and I only found out about it from this
Medium post.
I'm calling a REST request for authentication. And I need to get the session ID sending on response; in order to reuse that in my next request.
session id comes in Response header. When I use view result tree, this is not showing header parameters(response body has no data).
When googling I found a method using Regular expression Extractor method, but seems it works only when data in response body.
Nope, Regular expression extractor can search in headers also. You need to specify where to search.
See example,
This will search in headers and you can specify in main samples, sub samples also.
