Jmeter HTTP objects
Hello users,
I want to process a HTTP response after Jmeter performs a POST operation.
For this, I believe, that one needs to add a Beanshell Post processor to
process the HTTP response. Please correct me if I am wrong.
If I am correct, I want to know the object name that I need to reference in
my Beanshell PostProcessor. Is this documented some where?
Thanks,
/harsha

Storing yes. The random part you may or may not be able to do depending on
your test plan

Like I said, I have a HTTP sampler that POSTs a JSON payload to a CouchDB
server; The server returns a JSON response with the doc id. I want to store
only the doc id (after parsing response), and use it in in the next sampler
by GETing the document with the doc id.

The regex extractor itself lets you select a match number with a 0 for
random when multiple matches are found. so you should be able to us4e that
directory

My test plan looks something like this:
Post Thread group
Post HTTP request sampler
Extract_info (regex)
Get HTTP request sampler.
Any idea how to randomize this plan?

I am able to extract the required text from the POST response, and I feed it
immediately to a HTTP sampler that does a GET on it.
My test plan looks something like this:
Post thread group

hi
why do you need it written into a file? When you say 'parse' how many
elements are we talking about? or do you just want the entire response
written?
a regular expression extractor can extract out data into a variable that the
following samplers can use

My application returns a JSON payload as response. I want to parse the JSON
payload and write it into a file. I have another HTTP Sampler that
reads(__StringFromFile) this file and performs a GET on it.

I dont know why you want to do this since your requirements are satisified
without BeanShell, anyway,
the Sample Result is something that is passed to you , you dont have to
create it
>From here
http://jakarta.apache.org/jmeter/usermanual/component_reference.html#BeanShell_PostProcessor
You get
prev - (SampleResult) - gives access to the previous SampleResult
And from
http://jakarta.apache.org/jmeter/api/org/apache/jmeter/samplers/SampleResult.html#getResponseHeaders()
you get the correct method name
so
String str = prev.getResponseHeaders();
> log.info(str);
if you have errors in code you should see it in jmeter.log

After giving it a thought, I've decided that I should parse the response
data using a BeanShell PostProcessor.
I am adding a BeanShell PostProcessor to a HTTP Sampler (does a POST;
receives an XML response).
I am not too familiar with Java, so to start off, I wrote the following
snippet to understand if I am doing it right. I expect the HTTP response
header to be printed in jmeter.log, but I don't see it. I am doing something
wrong here or have I missed doing something completely?
import org.apache.jmeter.protocol.http.samplers.SampleResult;
SampleResult sr = new SampleResult();
String str = sr.getResponseHeadersAsString();
log.info(str);

Define what you want to do. There are other Post processors available. If
they dont satisfy your needs then you might want to look at BSF/Beanshell
Documents are here
http://jakarta.apache.org/jmeter/usermanual/component_reference.html#BeanShell_PostProcessor(note
the The following BeanShell variables are set up for use by the
script: ) and read about the objects at
http://jakarta.apache.org/jmeter/api/index.html
