Processing Rest2Soap Response with JsonSlurper When Identity Data Service Returns Empty Response

Processing JSON response from REST service and converting to SOAP format, managing error cases

Groovy Script

import groovy.json.JsonOutput

def parser = new groovy.json.JsonSlurper()
def jsonResp = parser.parseText(responseBodyTextToClient)

String adBilgisi = jsonResp.BilesikKutukBilgileri.TCVatandasiKisiKutukleri.KisiBilgisi.TemelBilgisi.Ad
String soyadBilgisi = jsonResp.BilesikKutukBilgileri.TCVatandasiKisiKutukleri.KisiBilgisi.TemelBilgisi.Soyad

if (adBilgisi == null || adBilgisi.isEmpty()) {
    statusCodeToClient = 503
    def pretty = JsonOutput.prettyPrint(JsonOutput.toJson([
        ad: "",
        soyad: ""
    ]))
    responseBodyTextToClient = pretty
} else {
    def pretty = JsonOutput.prettyPrint(JsonOutput.toJson([
        ad: adBilgisi,
        soyad: soyadBilgisi
    ]))
    responseBodyTextToClient = pretty
}

Explanation

This script performs the following operations:

1. Parsing JSON Response: Parses the JSON response coming from REST service using JsonSlurper.
2. Data Extraction: Extracts name and surname information from JSON structure.
3. Control and Conversion:
   • If name information is empty or null, returns an empty JSON response with HTTP 503 status code.
   • If name information exists, returns a JSON response containing only name and surname information.

Usage Scenario

This script processes the response from identity verification service:

• Returns error code in case of empty response
• Filters and returns only necessary fields in case of valid response

This script should be run on the response line (Response Policy) because it uses the responseBodyTextToClient variable.
