Hi all,
I have an requirement where I need to parse the data into the required format
Input:
{
"Message" : "\nRecord 1:\nRequired data is missing. \n\nRecord 2:\nprocessing failed\n"
}
Here the content and delimiters are not fixed. The fixed part is only /nRecord keyword on which I am writing the Script. But I am not getting desired Output using Groovy.
desired Output:
[{
"Record 1": "nRequired data is missing"
}, {
"Record 2": "processing failed"
}]
I have written Groovy Script for the same but I am getting empty array.
import org.apache.commons.io.IOUtils
import groovy.json.*
import java.util.ArrayList
import java.nio.charset.*
import java.nio.charset.StandardCharsets
import groovy.json.JsonSlurper
import groovy.json.JsonBuilder
def flowFile = session.get()
if(!flowFile) return
try {
flowFile = session.write(flowFile,
{ inputStream, outputStream ->
def text = IOUtils.toString(inputStream, StandardCharsets.UTF_8)
splitted = text.split('\nRecord')
int j = splitted.size()
final1 = []
for (int i=0;i<j-1;i++)
{
k = "Record " + splitted[i+1]
valid = k.replaceAll("\\n|\"|\\n|}","")
final1.add("{\"" + valid.replaceFirst(":",'":"')+ "\"}" )
}
def json = JsonOutput.toJson(final1)
outputStream.write(JsonOutput.prettyPrint(json).getBytes(StandardCharsets.UTF_8))
} as StreamCallback)
session.transfer(flowFile, REL_SUCCESS)
} catch(Exception e) {
log.error('Error during JSON operations', e)
flowFile = session.putAttribute(flowFile, "error", e.getMessage())
session.transfer(flowFile, REL_FAILURE)
}
Can you please help me with the same.
Thank you.
