How to save response in a variable in jmeter
I am performing load testing on my server using jmeter. In one of my post requests, I receive a unique id in the response. I need to send this id as a parameter in the following post requests. I am new to jmeter and don't have any idea how to do this. Help would be really appreciated.
Answer
If you need to store the whole response into a variable - take the following steps:
- Add Beanshell PostProcessor as a child of the request which returns response you're looking for
Put the following line into the PostProcessor's "Script" area:
vars.put("response", new String(data));Refer extracted value as
${response}where requiredSee How to Use BeanShell: JMeter's Favorite Built-in Component guide to lean more about Beanshell scripting in JMeter
Alternatively you can do the same with the Regular Expression Extractor, in that case relevant configuration will be:
- Reference Name:
response - Regular Expression:
(?s)(^.*) - Template:
$1$
If you need a part of response, not the whole response you can amend Regular Expression according to your needs as per Regular Expressions chapter of JMeter's User Manual
