How to access the hex request and response in a pre processor

[AlphaNiner1415]

Hi, so I tried to access the request/response of the sampler in a Beanshell Preprocessor with sampler.getSamplerData() and it is saying this method doesn't exist. So how can I get the request/response from the sampler?

Hi @AlphaNiner1415

I tried to access the request/response of the sampler in a Beanshell Preprocessor

In a Pre-Processor only the request can be accessed as the response is unknown until after the Sampler has run.
You may want to use a Post-Processor for the response.
Also, I would recommend using a JSR223 Post-Processor instead of Beanshell. See here and here.

sampler.getSamplerData() and it is saying this method doesn't exist

Not the Sampler but the SampleResult provides this method. Also not defined in a Pre-Processor.

So how can I get the request/response from the sampler?

1. In a Pre-Processor or Post-Processor:
   sampler.getRequest() will create and return the same ISOMsg object as the sampler will send.
   This will include fields added by an earlier Crypto PreProcessor (MAC, ARQC, etc.).
   For example, if you want the message content as a hex string:
   org.jpos.iso.ISOUtil.byte2hex(sampler.getRequest().pack())

2. In a Post-Processor:
   sampler.getResponse() will return the response ISOMsg the sampler received which you can turn into a hex string as above.
   The XML representation you would see in a "View Results Tree" can be accessed via prev.getSamplerData() for the request and prev.getResponseDataAsString() for the response.
   Note prev is the SampleResult object in a BeanShell or JSR223 Post-Processor.
