Add JSON Object to array - json

Question

After first system call fails, i am getting this json.
{
"header": {
"msgCode": "400",
"message": "Call failed!"
},
"body": {
"success": false,
"error_list": [
]
}
}
After every next system call fails, i am getting receipt_code, which i have to append to above json.
{
"header": {
"msgCode": "400",
"message": "Call failed!"
},
"body": {
"success": false,
"error_list": [
{
"errors": [
{
"message": "Invalid receipt code!"
}
],
"receipt_code": "A-11277809" //here is receipt_code
}
]
}
}
for all next calls if fail, then keep on appending this.
{
"header": {
"msgCode": "400",
"message": "Call failed!"
},
"body": {
"success": false,
"error_list": [
{
"errors": [
{
"message": "Invalid receipt code!"
}
],
"receipt_code": "11111"
},
{
"errors": [
{
"message": "Invalid receipt code!"
}
],
"receipt_code": "1222"
}
]
}
}
how can this be done by Groovy, any help
Here is my code
if(success!="true")
{
def receipt_code=receiptList[receiptFlag].receipt_code;
def error_list = []
def error ={
"errors": [
{
"message": "Invalid receipt code!"
}
],
"receipt_code": receipt_code //here is receipt_code
}
error_list.push(error)
error_list = JSON.stringify(error_list)
msg.put("error_list",error_list);
}
I am not able to add using above code

Using JsonSlurper
import groovy.json.*
String text = """
{
"header": {
"msgCode": "400",
"message": "Call failed!"
},
"body": {
"success": false,
"error_list": [
]
}
}
"""
def json = new JsonSlurper().parseText(text)
errors = [
['errors': [['message': 'hi']], 'code': 100],
['errors': [['message': 'hello']], 'code': 200]
]
for (err in errors)
json.body.error_list << err
println JsonOutput.toJson(json)
Output
{
"header": {
"msgCode": "400",
"message": "Call failed!"
},
"body": {
"success": false,
"error_list": [
{
"errors": [
{
"message": "hi"
}
],
"code": 100
},
{
"errors": [
{
"message": "hello"
}
],
"code": 200
}
]
}
}
