I need to change the http request name dynamically. I am extracting a number from one request and i have to send that to next request name. Any ideas on how to do this ?
welcome !!
Just extract number to variable and use regular jmeter variable substitution:
Sampler number ${var_with_number}

I'm using Jmeter to run a stress test for testing out my servers. I'm making several HTTP calls and in response, I get the HTTP response as a numeric string as "500". I want to extract that value from the response and store it in a variable. Also, I want to use that value in "If controller".
Help is appreciated.
Thanks,
Sid
The number can be saved into a JMeter Variable as follows:
Add Regular Expressions Extractor as a child of the request which returns the above numeric value:
Configure it as follows:
it will create ${value} JMeter Variable with the value of 500
If you want to use it in the If Controller you can compare the ${value} JMeter Variable with 500 using i.e. __jexl3() function like:
${__jexl3(${value} == 500,)}

New to Jmeter, I want to pass a variable of say "1234 567 8910" from a CSV file as a Param value to a HTTP GET request and I just can't seem to get it to work, tried a number of ways, any ideas ?
Complains with "java.net.URISyntaxException: Illegal character in query at index 71" which is the first space in the param.
Fixed by changing the csv file.....
If you need to pass this phone number as a GET request parameter just tick URL Encode? box in the HTTP Request sampler:
If you need to pass this phone number as a part of a GET request URL path - you can use __urlencode() function to wrap your variable from the CSV file:
${__urlencode(${variableFromCSV})}

I'm trying to extract variables returned from one HTTP request, use them in a second HTTP request then extract the variables returned from the second HTTP request.
I then need to use both the first extracted and second extracted variables in a third HTTP request.
I can extract the variables from the first HTTP request and use these in the second HTTP request but cant seem to get the variables extracted from the second HTTP request to then use in the third HTTP request.
Is it even possible to do this?
This is my current set up
It should be straightforward and possible as long as both extractors are going into unique variable names. The Debug Postprocessor will show you the values stored in each variable after a test run. What do you see in those in the context of the third http request?
I am wondering how I can use a dynamic variable in the Path field of a HTTP request . I am able to use User Defined Variables, but they are static, I need to use a variable that extracts some unpredictable value from the response of a previous HTTP request. I.e. the URL in the below scenario resolves literally to /this/and/that.jspx?param1=${testvar} , so you can see ${testvar} is not being substituted. How do I get ${testvar}, a variable created during regex extraction in a previous HTTP Request, to be substituted?
FYI I am using JMeter 2.11 and upgrading may not be an option (corporate policies... )
JMeter Variables resolution/substitution works normally no matter of JMeter version, I can think of 2 possible reasons:
You're looking into wrong place. You should be inspecting Request tab of the View Results Tree listener in order to see the actual URL
Your ${testvar} variable is not defined, i.e. Regular Expression Extractor fails to extract the required value. You can double check it using Debug Sampler:
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.
