Jmeter. Get current HTTP sampler body data from beanshell preprocessor

Question

Before send the query in HTTP Sampler I need to make some changes of this query in beanshell preprocessor. So, the question is how to access to current sampler body data from beanshell preprocessor? I can get Name,Path,IP, etc ( for example sampler.getPropertyAsString("HTTPSampler.domain")) but have no idea how to get the body data.

Answer 1

Kindly find answers below (assuming that we're talking about HTTP Request)

• Name: sampler.getName()
• IP: sampler.getUrl().getHost()
• Path: sampler.getUrl().getPath()

• If you need request parameters:

  Arguments arguments = sampler.getArguments();
  for (int i=0;i<arguments.getArgumentCount();i++)
  {
      Argument argument = arguments.getArgument(i);
      String name = argument.getName();
      String value = argument.getValue();
      // do what you need
  }
  

If you need more information refer to HTTPSamplerProxy JavaDoc

If it is not HTTP Request you can figure out what class this sampler variable refers to as

log.info(sampler.getClass().getName());

figure out class name from jmeter.log file and look for JavaDoc.

For more information regarding Beanshell scripting refer to How to use BeanShell: JMeter's favorite built-in component guide.

Thanks @Dmitri T

I was getting 13:28:13 ERROR - jmeter.util.BeanShellInterpreter: Error invoking bsh method: eval Sourced file: inline evaluation of: ``import org.apache.jmeter.protocol.http.control.Header; sampler.getHeaderManag . . . '' : Typed variable declaration : Class: Arguments not found in namespace error while using

Arguments arguments = sampler.getArguments();
for (int i=0;i<arguments.getArgumentCount();i++)
{
    Argument argument = arguments.getArgument(i);
    String name = argument.getName();
    String value = argument.getValue();
    // do what you need
}

After importing import org.apache.jmeter.config.Argument; import org.apache.jmeter.config.Arguments;

I solved this
