How to print or get the HTTP POST request body in JMETER

UseCase: I am running Jmeter from command line to generate Dashboard. For failed cases I need to capture Request Body.

Answer 1

One of the options would be using JSR223 PostProcessor and the following code:

log.info(sampler.getMethod() + ' ' + sampler.getUrl().toString())

sampler.getArguments().each {arg ->
    log.info(arg.getStringValue())
}

It will print request method, URL and all the parameters along with values to jmeter.log file:

in case of HTTP Request sampler stands for HTTPSampleProxy, see the JavaDoc for available methods and fields and Apache Groovy - Why and How You Should Use It article to learn more about Groovy scripting in JMeter
