How to pass the response header to authorized api using Jmeter? - jmeter

I am using Regular Expression Extractor for extracting the header values.
Here is my test plan structure.
I am getting a response in login api is
I want to extract the SRToke, Id1, Id2 and Id3 values from above response header. So I have used Regular Expression Extractor as below
I have also used BeanShell PostProcessor
Now I am getting the error 401 in result
Please give me the solution, what I have done wrong here?

First you need to extract the variables from Response Header section of your Login request. Please refer how to capture from here. https://stackoverflow.com/a/57391175/4481179
After extracting, use HTTP Header Manager as a child of Eventlist Sampler and pass that extracted value as shown below:

You get an error about 401 because you did not add authorized success. You need to know the flow of the system. Maybe its need another parameter beside one parameter BEARER like you.

I think Beanshell won't be required as you are not correlating from cookies, try to find the missing header under the 401 transaction something like Authorization and place the correlated variable there.

How I extract the x-csrf-token in request header and pass to post https request in jmeter?

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

JMeter RegUx User Parameters not adding parameter

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 $2$

In jmeter : how to extract values from two different json response and use that extracted values as a parameter for new http request

In jmeter: I’m using two http requests in one thread group, so I’m getting two response from those http requests.
I need ‘member id’ from one response and some string(digest) from other response, in order to create third http request.
I have extracted 'member id' by using this regular expression: {"Id":(.+?)}
which return me correct member id.
Response from 2nd request is string(digest) : "G9V6Su9PESaobcInErdD7Y8OKNo="
I added one more regular expression to extract this string : "(.+?)"
I have added two debug sampler as I'm using two regular expression extractor.
then I pass extracted values 'member id' and string(digest) as a parameter to third http request.
When I run it I'm getting error, my 3rd http request failed.
It's failing to pass extracted 'member ID', but its correctly pass string(digest)
In first debug sampler: its showing correct extracted 'Member ID' but some different values for digest field.
In 2nd debug sampler: its showing correct extracted 'digest' field but some different value for 'Member ID'.
I’m doing it all under one thread group
I'm new to jmeter, I don’t know whether it is possible to extract field from two different response and use as parameter to create new http request.
if it possible how to do it please help me.
Thanks in advance.
I believe that it's due to including quotation marks (and who knows what else) into the "Id" regular expression, you need to surround it with quotes like:
{"Id":"(.+?)"}
Also the better way of working with JSON data is JSON Path Extractor which is available via JMeter Plugins project. See Using the XPath Extractor in JMeter guide (scroll down to "Parsing JSON") for more information on installation, usage, syntax, etc.

JSON Path Extractor in JMeter

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.

Capture a header value from the response in Jmeter and re-use

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.
