Parsing SOAP Message with XmlSlurper and Adding Value to Header Field to Send to Backend

Parsing SOAP message with Groovy script and adding value to header field to send to backend

Groovy Script

import groovy.xml.XmlSlurper
import groovy.xml.XmlUtil
import groovy.xml.StreamingMarkupBuilder

try {
  def namespacePrefix = 'sch'
  def namespaceUri = 'http://kurum.com/ws/some-func-ws/schemas'
  def userName = request_usernameOrKey

  // Parse XML using XmlSlurper and define namespaces
  def rootNode = new XmlSlurper(false, true).parseText(requestBodyTextFromClient).declareNamespace(
    'soapenv': 'http://schemas.xmlsoap.org/soap/envelope/',
    'sch': 'http://kurum.com/ws/some-func-ws/schemas'
  )

  // Check if Header section exists, create if not
  def headerNode = rootNode.'soapenv:Header'
  if (!headerNode) {
    headerNode = rootNode.appendNode { 'soapenv:Header' {} }
  }

  // Create and add userId element
  def userIdNode = new XmlSlurper(false, true).parseText("<${namespacePrefix}:userId xmlns:${namespacePrefix}='${namespaceUri}'>${userName}</${namespacePrefix}:userId>")
  headerNode.appendNode { mkp.yield userIdNode }

  // Serialize updated XML as string
  def outputXml = XmlUtil.serialize(new StreamingMarkupBuilder().bind {
    mkp.declareNamespace('soapenv': 'http://schemas.xmlsoap.org/soap/envelope/', 'sch': 'http://kurum.com/ws/some-func-ws/schemas')
    mkp.yield rootNode
  })

  requestBodyTextToTargetAPI = outputXml
} catch (Exception e) {
  e.printStackTrace()
}

Explanation

This script performs the following operations:

1. XML Parse: XML data coming from request body is parsed
2. Header Check: Checks if SOAP Header field exists, creates if not
3. Username Retrieval: Username information from authentication is retrieved
4. Adding to Header: Username information is added to Header field
5. Sending to Backend: Updated XML is sent to backend

This script should be run on the request line (Request Policy) because it uses the requestBodyTextFromClient and requestBodyTextToTargetAPI variables.
