Script Assertion To Grab 4 'Set-Cookies' To Set 1 'Cookie' Header In Follow Up Request

Hi,   This is related to my other 'cookie' post - but that other post has side tracked onto another issue I need to solve - so I've created a second post with a specific issue.   A while back...

    Finally, simulated the issue.

     

    Here you go:

     

    def nextStepName = 'REST Request'
def headerToLook = 'Set-Cookie'
def headerToSet = 'Cookie'

def nextRequest = context.testCase.testSteps[nextStepName].httpRequest
def headers = nextRequest.requestHeaders
def showHeaderCount = {msg -> log.info "Header count ${msg} is: headers.size()" }
showHeaderCount('before')
if (headerToSet in headers.getKeys()) {
	headers.remove(headerToSet)
	showHeaderCount('after')
}
if (messageExchange.responseHeaders.containsKey(headerToLook)) {
  log.info "Found ${headerToLook} in the response headers"
  def cookiez = messageExchange.getResponseHeaders().get(headerToLook)
  def computedValue = cookiez.collect { it.split(';').first()}.join('; ')
  log.info "Value for Cookie header is evaluated to : ${computedValue}"
  headers.put(headerToSet, computedValue)
  log.info 'Headers updated'
  nextRequest.requestHeaders = headers
  log.info headers
} else {
  log.warn "Not Found ${headerToLook} in the response headers"
}

What does it show if you add below statement after

"def cookiez = messageExchange.responseHeaders['Set-Cookie'].value"

 

log.info cookiez.size()

Also you may try adding  below instead of "list.add(cookies.toString())"

list.add(cookies.split().first())

    Hey!

     

    nmrao adding the following

     

    log.info cookiez.size()

    immediately after 

    def cookiez = messageExchange.responseHeaders['Set-Cookie'].value

    Returned the following:

     

    Wed Jun 19 01:08:49 BST 2019: INFO: Found Cookie in the response headers
Wed Jun 19 19:53:36 BST 2019: INFO: Found Cookie in the response headers
Wed Jun 19 19:53:36 BST 2019: INFO: 4

     

    but when I commented out 

    list.add(cookies.toString())

    and replaced with

    list.add(cookies.split().first())

    I got an assertion failure on the script assertion - it was a nullpointer - I've attached the stacktrace if it helps at all.

     

    Currently the script assertion is as follows:

     

    //Courtesy of Rao
//This script assetion reads the http response, 
//collect the cookies for the next http request
//Provide the next step name where you want to set the Cookie to the request or
//Use property expansion for below
def nextStepName = 'REST Request'
def nextRequest = context.testCase.testSteps[nextStepName].httpRequest
def headers = nextRequest.requestHeaders
if (messageExchange.responseHeaders.containsKey('Set-Cookie')) {
  log.info "Found Cookie in the response headers"
  def cookiez = messageExchange.responseHeaders['Set-Cookie'].value
log.info cookiez.size()  
  def list = []  
  cookiez.each { cookies ->
     //def (name, value) = cookies.toString().split('=',2)
     list.add(cookies.toString())
     //list.add(cookies.split().first())
     
  }
  headers['Cookie'] = list
} else {
  log.warn "Not Found Cookie in the response headers"
}
nextRequest.requestHeaders = headers

    Thanks guys - Im sorry I cant do anymore to help - feels a bit cheeky - but I just dont know how to proceed!

      Would you please try below?

       

      def nextStepName = 'REST Request'
def nextRequest = context.testCase.testSteps[nextStepName].httpRequest
def headers = nextRequest.requestHeaders
if (messageExchange.responseHeaders.containsKey('Set-Cookie')) {
  log.info "Found Cookie in the response headers"
  def cookiez = messageExchange.responseHeaders['Set-Cookie'].value
  def computedValue = []
  computedValue << cookiez.flatten().collect { it.split(';').first()}.join('; ')
  headers['Cookie'] = computedValue
} else {
  log.warn "Not Found Cookie in the response headers"
}
log.info headers
nextRequest.requestHeaders = headers

        nmrao,

         

        Hey man - unfortunately the script assertion failed with the following snippet from the stacktrace :(

        Thu Jun 20 23:18:43 BST 2019: ERROR: Error in assertion script of the [GET Cookies] test step

        I got real excited when I thought this was it - this is the last piece in my ridiculous 16 step authentication process!

         

        As always  - I really appreciate the help - feels like you're doing all the work (which you are) - so please dont think I dont appreciate what you're doing,

         

        nice one,
