I have recorded a workflow in Jmeter using Recording controller.
In that workflow, a URL parameter 'member_id' get generated and appear in URL.
This 'member_id' is getting used further in the workflow.
In the recorded script, value of 'member_id' is saved in a variable. Screenshot
Here the problem is; When I execute the scripts, then instead of newly generated 'member_id', the saved value is getting used in the later samples.
I want to fetch the new value and update the saved value, so that it can be used in later samples
I have tried to fix this issue by fetching the 'member_id' from the URL and save it in a variable
I have tried 'Regular Expression Extractor' but I am not able to read the value.
Screenshot
But when I print the response, I am getting only first digit of new 'member_id'.

You're using wrong regular expression, it stops whenever it finds the first match
According to the JMeter documentation on Regular Expressions:
( and ) these enclose the portion of the match string to be returned
. match any character
+ one or more times
? don't be greedy, i.e. stop when first match succeeds
So the solution will be to remove the question mark from your regular expression:
member_id=(.+)
or even better, if you're looking for numbers you should limit your search criteria to digits only like:
member_id=(\d+)

this works, but how can I ignore the quotation marks in the form of my token "token"
i don't want him to get the quotation marks
I would use Boundary Extractor
Put Left and Right Boundary as " and you will get the value
Allows the user to extract values from a server response using left and right boundaries. As a post-processor, this element will execute after each Sample request in its scope, testing the boundaries, extracting the requested values, generate the template string, and store the result into the given variable name
You need to provide the Template and specify the capturing group (in your case it will be 1)

Using RegEx (Regular Expression Extractor) with JMeter
working in this way. maybe you will need it!
I'm trying to use regular expression extractor concept in Jmeter. By using regEx concept I'm able to get the required token id's. And for all I'm using regEx as (.*?). So this is working fine when we have constant prefix and suffix text/values.
But in this case, there is no suffix,
Ex: Key is = #bluerelay.com/a43a816dcdd14873bd5757b3a3709d5c,
ClickHereForImageForm
I want to take the key ID into a variable with using RegEx. I have tried to get it with (.*?) but it didn't work, it returns the full value, not the required part. It'd be excellent if you could give any suggestion.
The source value is:
https://navitus-internal-app.bluerelay.com/#/token/systemadministrator#bluerelay.com/a43a816dcdd14873bd5757b3a3709d5c
The expected result is to extract a43a816dcdd14873bd5757b3a3709d5c from the above URL and put it into a variable.
You can use regex to get last text after / sign
(.*)\/(\w+)

How can I extract the response using a regular expression for Jmeter.
Jmeter is not extracting the response item that I want to extract. I've tried several times, but I failed. How can I extract the response item?
Response data is as shown in the screenshot:
The value which I need to extract has been highlighted.
I tried extracting using the following expression, but it failed:
<h2>.+?<a hfref="http://(.+?)">.+?</a>.</h2>
Please follow the below steps to extract the Id value.
In your Regular Expression Extractor, configure below details. Use the regular expression as Public/FormsPreview.aspx\?Id\=(.+?)& to retrieve the Id.
You can use other unique left/right boundaries as well, as your regular expression.
How to validate your regular expression extractor?
To validate your regular expression extractor, add a Debug Sampler (Right Click on your thread group > Add > Sampler > Debug Sampler)
Execute the test plan
In View Results Tree you can see the c_ID value as shown below.
Depending on how vary can result be (I mean, how the form is changing? is that only querystring Id parameter that is different? could there be another response (than Object Moved) with Id that you don't want to parse? etc.), the regular expression in the Regular Expession Extractor Post-Processor (which fits best here) would be different.
From simplest context-agnostic, Id=(\d+) (that is considering you have numeric Id), to making it case-insensitive (?i)Id=(\d+) and/or alphanumeric Id=([0-9a-zA-Z]+), or even whatever symbols are in (but you'd be forced to start to include context in this case ) Id=(.+?)& - and up to one that uses broader context evaluating the whole multiline stuff, like (?im)<title>Object\smoved</title>.+<a\shref=.+Id=(\d+)
And don't forget to use $1$ as your Template and take the Match 1.
I suggest you to stick to the most narrow and most context-agnostic one you can afford (the very first example here).
Add some assertions to make sure you're on the right page - despite the fact they executed after post-processors, you'd see something is wrong, at least.
You can add regular expression extractor like following
How to pass jmeter response data (ex: getting response 295 without any lable) to next http request url path/body. This 3 digits/4 digits number is dynamically generated for every run and this value i have to use it for next API calls. Since this value is not having any lable/attribute name not sure how to extract this value. Please suggest.
Regular Expression Configuration:
Reference Name: anything
Regular Expression: (.+)
Template: $1$
Match No.(O for Random): 1
The Reference name should be passed as the variable in the next HTTP request URL path/body.
Screenshot from Regex Test in View Results Tree.
If you need to extract a single numeric value, the relevant regular expression will be as simple as (\d+). See Perl 5 Regex Cheat sheet for quick reference.
If in future you will need a regular expression which return the whole response (including line breaks, special characters, whatever), as per How to Extract Data From Files With JMeter article it will be something like (?s)(^.*)
I did read few responses but my regular expression extractor is not working.
Mine is a simple case where this is my response
token.id=AQIC5wM2LY4Sfcz4cOT2RrremxWJmM3llZmPl6k0bP_r5D4.AAJTSQACMDUAAlNLABQtNDI1OTg4NzgxODg5MDM1ODU2NQACUzEAAjI3
I am trying to grab the value using this expression
token.id="(.*?)"
which is not saving the value into the variable i assigned. My next request when trying to use the value fails since its not grabbing it.
Can someone let me know what exactly is missing. thanks.
There are few problems with your regular expression:
You need to escape dot between "token" and "id" with backslash as it is a special character. See Literal Characters article for more information.
You don't need the quotations marks as your response doesn't contain them (does it?)
So your regular expression needs to be amended as token\.id=(.*) (however I would rather go for something like token\.id=(\w.+)
You can use View Results Tree listener in "RegExp Tester" mode to test your regular expressions directly against response without having to re-run the request.
See Regular Expressions JMeter documentation chapter and How to debug your Apache JMeter script guide for extended information on the above approaches.
