How Can i extract value from DWR call using RegEx in jmeter.
In My Script Request Body is something like :
POST data:
`callCount=1`
`page=/abc/xyz.action`
`httpSessionId=`
`scriptSessionId=87F34A5261EFBF481F6D421920EF99F9406`
`c0-scriptName=DWRPostHelper`
`c0-methodName=savePostAsDraft`
`c0-id=0`
`c0-param0=string:447`
`c0-param1=number:933`
`c0-param2=number:0`
`c0-param3=string:Post%20Jmeter`
`c0-param4=string:`
`c0-param5=string:1`
`c0-param6=number:1427199824585`
`batchId=4`
And Response data is as below :
`//#DWR-INSERT`
`//#DWR-REPLY`
`dwr.engine._remoteHandleCallback('4','0',["447","Auto-saved at 17:55"]);`
Need to Extract value 447 from above Response.
is it Possible Using RegEx ? or is there any other way to do the same?
'dwr\.engine\._remoteHandleCallback\('[0-9]','[0-9]',\["([0-9]+)",
This should do it, written from memory, you may need to tweak the syntax a bit. Use $1$ for the template.
Try the following:
dwr\.engine\._remoteHandleCallback\('4','0',\["(.+?)"
Make sure that you set $1$ as "Template"
You can test your regular expressions using View Results Tree listener as follows:

I'm new here and also a beginner on JMeter and maybe this was already answered in an old post that I didn't find, sorry if this is the case.
I had this Post request I need to send with all these IDs that vary according to the account
Post Request
In order to get all of the IDs, I used the JSon extractor to put then into a variable
JSon extractor, then I got all the FieldIDs that I need.
ID extracted
But now how can I add this variable inside the request? I tried something like {"ids":"${fieldId}","includeBoundary":true} but it didn't work. How can I use this?
Please see: HTTP Request parameter dialog example
If you need to extract the whole response, save it into a JMeter Variable and send it back to another endpoint - the easiest way is using Boundary Extractor providing empty left and right boundaries
If you need more complex transformations - take a look at JSR223 Test Elements and Groovy language
I solved my problem in a so easy way(damn it)!!!!
On the Json extractor I just marked the option "Computer concatenation var (suffix_ALL)" then on the debbuger I got all IDs I needed in only one line and finally on my request I just add on the body data the line {"ids": [${fieldId_ALL}],"includeBoundary":true} and bingo it worked like a charm!!!!
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
I have a looping process that will extract some values from a web service (working) and loop through to pull all the information for each value (working).
I need to capture the whole return into a variable so I can modify it and post it back up later.
Screenshot:
When the "Baseline for ..." get kicks in, I get the proper response
But the "Get response" BeanShell PreProcessor is picking up old responses
Screenshot:
Given where my "Get response" object is, I would assume the:
vars.put("ResponceData", prev.getResponseDataAsString());
...would grab the response from "Baseline for ${ID} of site ${callSite}". Please help!
You are using wrong test element. Beanshell PreProcessor is being executed before request therefore it acts properly and returns response from the previous request instead of current one. You need to change it to the Beanshell PostProcessor and your code will start working as you expect.
It is recommended to avoid scripting where possible, if you need to save response data into a JMeter Variable you can do it using i.e. Regular Expression Extractor. According How to Extract Data From Files With JMeter article the relevant configuration will be something like:
Reference Name: ResponceData
Regular Expression: (?s)(^.*)
Template: $1$
If you face a JMeter limitation which cannot be worked around without using scripting make sure you are using the most performing scripting language, since JMeter 3.1 it is recommended to use JSR223 Test Elements and Groovy language
In this example request 226 is main Post request which internally executes 1 Post and 2 Get requests during run time. how i can extract dynamic code value from one of Get request of 226 which is input for the request 228.
I know how to extract from response using RegEx and Xpath. I this case need help Passing Data From a Request to Another Request
Hopefully you've already found the solution, but I believe that is what you've been looking for:
To extract data from a response, you can go for Regular Expression Extractor in this case which is faster and consumes less memory and CPU compared to other extractors like XPath which is worse.
This blog has decent info on extracting information using Regular Expression Extractor.
You are already saying that you know how to use them. Then it is very easy to pass the value to another request. You just use the variable using below syntax to access the value - ${variablename}. Whereever you need to substitute the value, just use ${variablename}.
Ex: code=${code}&stats=${stats}
Remember: Scope of this variable is within the thread for a thread group.
I don't think you will be able to bypass OAuth 2.0 login challenge using correlation. See How to Run Performance Tests on OAuth Secured Apps with JMeter for feasible options.
you can use beanshell sampler to process the results and have prev to get the list of results
org.apache.jmeter.samplers.SampleResult [] temp=prev.getSubResults();
print(temp[2].getURL())
I have a series of interconnected pages to test using JMeter. The problem is that the initial page has a Javascript variable in source section which is more of a session variable. This variable is passed in the URL for subsequent pages.
So basically I would like to fetch this javascript variable when I load the initial page from the source section and pass it to next URL(s).
Is there a way I can achieve this using JMeter.
Are you able to see the session variable in the response of initial page?
(in view result tree listener)
If yes, then correlate this value and pass the variable in to next request (use regular expression extractor for fetching the value, still if you are finding some issue in correlating the value than please share the response of first request over here so that I can provide you regx for that)
People mostly Regular Expression Extractor to fetch dynamic values from previous responses, in general the process looks like:
Add Regular Expression Extractor as a child of the request which returns desired data
Use Perl5-style regular expression to match what you're looking for
Provide a template to choose match group - ususally $1$ if you looking for a single value
Provide a reference name to refer the extracted value, i.e. foo
Use extracted value as ${foo} where required
You can visualise JMeter Variables using Debug Sampler and View Results Tree listener combination.
The easiest way to debug your regular expressions is using View Results Tree listener in "RegExp Tester mode"
