具有Groovy的Jmeter PostProcessor，并获取响应数据的内容

Question

In JSR223 PostProcessor I am using this method to get the response data:

def json = new JsonSlurper().parseText(response)

Here is a snippet of my json output is like this

XmlItemResult:[[xPath:/Blocks/Block[001], name:abc, folder:\A\abc\a1, id:84, information:[[xPath:/Blocks/Block[001], result:Block number 1: abc], [xPath:/Blocks/Block[001]/Steps/CallSteps/Step[001], result:Call step StepNo 1], 

folder:\\Voice133, id:2542, information:[[xPath:/TestCases/TestCase[001],

This response, as you see contains two things which I am interested in:

folder:\A\abc\a1, id:84,
folder:\Voice133, id:2542,

I need to get the id value for only this line --> folder:\\Voice133, id:2542,
note 2542 is variable and can be different each time and after each run.

I tried

json.find ("Voice133, id:(.+?),")

Your string is not a valid JSON, you can check it yourself using any online JSON validator , therefore you won't be able to use JsonSlurper , you will have to go for Regular Expressions instead.

In Groovy you can use =~ - Find Operator in order to be able to extract the required value(s), example code would be something like:

def response = 'XmlItemResult:[[xPath:/Blocks/Block[001], name:abc, folder:\\A\\abc\\a1, id:84,' +
        ' information:[[xPath:/Blocks/Block[001], result:Block number 1: abc],' +
        ' [xPath:/Blocks/Block[001]/Steps/CallSteps/Step[001], result:Call step StepNo 1], '

def matcher = (response =~ 'folder:\\\\A\\\\abc\\\\a1, id:(\\d+),')

if (matcher.find()) {
    log.info('Folder ID = ' + matcher.group(1))
}
