I need to extract the string to the right of the equal sign character in an Apache Jmeter project. I am not familiar with Regular Expression syntax at all, but I think this would be the easiest way to extract it. The url is: https://myserver.com:portnum/im;jsessionid=48E10C95151BFB84D795C90FBC31E8E6
I only need the string to the right of the equal sign, not including the equal sign. My question is, what regular expression should I use to extract the string? Thanks!
It is as simple as =(\w+)

Also be aware that there are "smarter" ways of handling JSESSIONID:
In case if it comes as a Cookie you can get its value via HTTP Cookie Manager
If it is being passed as an URL parameter you could use HTTP URL Re-writing Modifier

Example:
In a response headers I see,
state=a5d73a14-a728-4f0f-afae-de5fda55d002
Here I can use LB as state= and there is no right boundary.
So I tried using regular expression extractor as:
state=(.+)
and replaced the hard coded value in the next request as ${state}
The requests are failing as it takes ${state} itself in the request URL, it means regular expression extractor is not working. I know I have placed the function rightly. Still I don't know what I am doing wrong here. Any suggestion would really help!
Should search the response in main and sub samples. Before I was searching for response only in main sample's so it failed.
same regular expression worked: when there is no right boundary or new line right boundary.
state=(.+)
enter image description here
Actually your regex should work, maybe it fails due to line break or something, to be on the safe side try using state=(.*) as the regular expression, it should be less restrictive:
Also the value of your "state" looks like a GUID so you can try looking up a guid-like structure instead:
state=([A-Fa-f0-9]{8}[\-][A-Fa-f0-9]{4}[\-][A-Fa-f0-9]{4}[\-][A-Fa-f0-9]{4}[\-]([A-Fa-f0-9]){12})
And last but not the least, by default Regular Expression Extractor looks into response body so you need to change the "Field to check" to Response Headers

Using Regular Expressions to Extract Tokens and Session IDs to Variables
From the below string
https://ABC.somewebsitename.com/Account/AutoLogOn?token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJzdWIiOiIxMDEyMzk3ODMiLCJ0YXJnZXRDb3VudHJ5Q29kZSI6IkpQIiwiZXhwIjoiMTU3OTUxMjc4MiJ9.QhfDKvZXSrqTjGYsBaZUd6ErbYoOJUdta0efws2SI-nv0VYqUvByHvoKbWVGvd89RmOi-KV33CDHU8NE_Pl0NA
I want to extract the value after token and send it as a parameter in next request for that I used Regular Expression extractor as below
But in the next request parameter, I am not able to get those values
Am I missing something, can you help me on this?
Note: I have followed the link Extract Location from Response Header with JMeter but still no use.
Your regular expression is missing capturing group, I believe you should amend it like:
https.+token=(.*)
Demo:
However if you just need to extract the token and append it to the next request it is easier to consider Using the HTTP URL Re-writing Modifier
Regular expression should be token=(.+?)$
Also set the Field to Check to URL in the Regular Expression Extractor element.
I did some trial and error, and got the answer,
In the Regular Expression Extractor, used as
Regular Expression: Location: .+\/AutoLogOn\?token=(.*?)\n
I'm using jmeter to try and test a website. I'm currently having issues extracting information that is returned.
For instance I send a HTTP request to:
https://intranet.company.com/Capps/f?p=101:1:
The website responds with:
https://intranet.company.com/Capps/f?p=101:1:11016690116729:::::
The new string of numbers listed at the end of response is the session id that I must use to test other pages of the program. I've been trying to use a reg Ex extractor but I cannot seem to pull the number off the url. I am currently using jmeter 3.1
Regular Expressions I've tired:
f?p:101:1:([0-9]{16})::
f?p=([0-9]{1,3}):([0-9]{1,3}):([0-9]{16}):
And various similar expressions, but none have worked for me. If I set up the website with no session ids it will work, but the website is required to use session ids.
Thanks for any help you may provide,

You need to escape ? sign as it is a meta-character and might be interpreted as repetition pattern
For some reason you are trying to extract 16-digit long integer while your id is 14-digit long
I would suggest the following Regular Expression Extractor configuration:
Field to check: URL
Reference Name: anything meaningful, i.e. id
Regular Expression: f\?p=101:1:(\d+):
Template: $1$

I don't know anything about jmeter, but I guess it supports standard regex syntax. In your regular expressions, you are expecting a numeric session id with a constant length of 16. However, the session id is not necessary 16 digits long. In your own examples, it has 14 digits. If I check the session length on my oracle apex cloud account, it is 13 digits long.
I guess you cannot rely on its constant length, therefore, try to use something like this:
f?p=([0-9]{1,3}):([0-9]{1,3}):([0-9]{10,16}):
Or even this:
f?p=([0-9]{1,3}):([0-9]{1,3}):([0-9]*):
Also check out the following link and scroll down a bit. Guru Jeff Kemp already did something like this.

Chris Muir covered it in his comprehensive post on configuring jmeter specifically for APEX. It's dated, but I'm pretty sure it still holds up.
c) sessionId Regular Expression Extractor
f?p=([0-9]{1,3}):([0-9]{1,3}):([0-9]{16}):

This appears to be what you've tried, but it seems like there may be other settings and considerations.
As I am new in using jmeter I'm stuck to write regular expression for this expression:
/catalog/search_display?category_id=9">Parts</a>
Can somebody help me out.
/catalog/search_display\?category_id=9">Parts</a>
Is that what you need? The question mark needs to be escaped, I don't see anything else noteworthy about it. The JMeter regexes are not enclosed in // and thus the slash is not a special character.
What do you want to extract? I assume that it is 9 (category_id). In that case regular expression extractor configuration should look like:
Reference Name: anything meaningful, i.e. id
Regular Expression: <a href="/catalog/search_display\?category_id=(.+?)"
Template: $1$
Refer extracted value as ${id} where required.
Mention that question mark needs to be escaped by a back slash as it is reserved character in regular expressions.
See Regular Expressions chapter of JMeter's User Manual for Perl5-style regex syntax and examples.
Also be aware that it isn't very recommended to parse HTML using regular expressions and it might be better to use the following post processors instead:
CSS/JQuery Extractor
XPath Extractor
I have an http post request which replies with a number in the response body.
I am trying to use a Regular Expression Extractor to extract this number:
I am doing another post request using the extracted value. Unfortunately, the variable seems to be null.
Any idea of what could be wrong?
I am using JMeter 2.13.
There are 2 available solutions:
Use ${REGION_ID_g0} when referring extracted value
Change your regular expression to add grouping as (\d+)
