how to apply if-else for a complex JSON array - arrays

Question

here is the Sample Json:-
[
{
"index": 0,
"object": {
"uri": "entities/oAFpSUX",
"type": "configuration/entityTypes/Pet",
"createdBy": "abc#xyz.com",
"createdTime": 1531431176965,
"updatedBy": "abc#xyz.com",
"updatedTime": 1531431177691,
"attributes": {
"Weight": [
{
"label": "5 lbs",
"value": {
"PetWeightMeasurement": [
{
"ov": true,
"value": "5",
}
],
"PetWeightUOM": [
{
"ov": true,
"value": "lbs",
"lookupCode": "lbs",
}
]
},
"ov": true,
"uri": "entities/oAFpSUX/attributes/Weight/1AeFvD8Kj"
}
],
"Identifiers": [
{
"label": "5155445576",
"value": {
"Type": [
{
"ov": false,
"value": "CRMO_Pet_Id",
}
],
"ID": [
{
"ov": true,
"value": "5155445576",
}
]
},
"ov": true,
"uri": "entities/oAFpSUX/attributes/Identifiers/1AeFvCrHh"
}
],
"Vaccination": [
{
"label": "Bordatella - 2018-10-26",
"value": {
"Type": [
{
"type": "configuration/entityTypes/Pet/attributes/Vaccination/attributes/Type",
"ov": true,
"value": "Bordatella",
"lookupCode": "4",
"lookupRawValue": "Bordatella",
"lookupAttributes": [
{
"name": "Sort Order",
"value": "3"
}
],
"uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9yGr/Type/1AeFvA2X7"
}
],
"ExpirationDate": [
{
"type": "configuration/entityTypes/Pet/attributes/Vaccination/attributes/ExpirationDate",
"ov": true,
"value": "2018-10-26",
"uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9yGr/ExpirationDate/1AeFvA6nN"
}
]
},
"ov": true,
"uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9yGr"
},
{
"label": "Distemper - 2018-10-25",
"value": {
"Type": [
{
"type": "configuration/entityTypes/Pet/attributes/Vaccination/attributes/Type",
"ov": true,
"value": "Distemper",
"lookupAttributes": [
{
"name": "Sort Order",
"value": "4"
}
],
"uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9YhJ/Type/1AeFv9cxZ"
}
],....
My question: I was able to get the value of "$..Vaccination..value.Type..value" as "Bordatella" so that works fine. However what I now want is that if the value is 'Bordatella' then I want to extract the "value" under "ExpirationDate". Can someone please help me how I can extract that "value" under "ExpirationDate" ? I am not sure if I need to do that with some custom Groovy code of using jmeter's if controller. Any help would be greatly appreciated!
Thanks.

Answer 1

There are several ways to run jq queries from within Java - e.g.
https://github.com/eiiches/jackson-jq
https://github.com/arakelian/java-jq (available from Maven Central)
Java Native Access wrapper https://github.com/bskaggs/jjq . Supported platform is Linux only.
Assuming the sample input has been revised in the obvious way to make it valid JSON, the following jq filter will produce the output as shown:
.[].object.attributes.Vaccination[].value
| select(.Type[].value == "Bordatella")
| .ExpirationDate[].value
Output:
"2018-10-26"
Alternative
Here's a jq filter that is agnostic about the relative location of the "Vaccination" object:
..
| objects
| select(has("Vaccination"))
| .Vaccination[].value?
| select(.Type[].value == "Bordatella")
| .ExpirationDate[].value

Given the following JSON response:
[
{
"index": 0,
"object": {
"uri": "entities/oAFpSUX",
"type": "configuration/entityTypes/Pet",
"createdBy": "a...#xyz.com",
"createdTime": 1531431176965,
"updatedBy": "a...#xyz.com",
"updatedTime": 1531431177691,
"attributes": {
"Weight": [
{
"label": "5 lbs",
"value": {
"PetWeightMeasurement": [
{
"ov": true,
"value": "5"
}
],
"PetWeightUOM": [
{
"ov": true,
"value": "lbs",
"lookupCode": "lbs"
}
]
},
"ov": true,
"uri": "entities/oAFpSUX/attributes/Weight/1AeFvD8Kj"
}
],
"Identifiers": [
{
"label": "5155445576",
"value": {
"Type": [
{
"ov": false,
"value": "CRMO_Pet_Id"
}
],
"ID": [
{
"ov": true,
"value": "5155445576"
}
]
},
"ov": true,
"uri": "entities/oAFpSUX/attributes/Identifiers/1AeFvCrHh"
}
],
"Vaccination": [
{
"label": "Bordatella - 2018-10-26",
"value": {
"Type": [
{
"type": "configuration/entityTypes/Pet/attributes/Vaccination/attributes/Type",
"ov": true,
"value": "Bordatella",
"lookupCode": "4",
"lookupRawValue": "Bordatella",
"lookupAttributes": [
{
"name": "Sort Order",
"value": "3"
}
],
"uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9yGr/Type/1AeFvA2X7"
}
],
"ExpirationDate": [
{
"type": "configuration/entityTypes/Pet/attributes/Vaccination/attributes/ExpirationDate",
"ov": true,
"value": "2018-10-26",
"uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9yGr/ExpirationDate/1AeFvA6nN"
}
]
},
"ov": true,
"uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9yGr"
},
{
"label": "Distemper - 2018-10-25",
"value": {
"Type": [
{
"type": "configuration/entityTypes/Pet/attributes/Vaccination/attributes/Type",
"ov": true,
"value": "Distemper",
"lookupAttributes": [
{
"name": "Sort Order",
"value": "4"
}
],
"uri": "entities/oAFpSUX/attributes/Vaccination/1AeFv9YhJ/Type/1AeFv9cxZ"
}
]
}
}
]
}
}
}
]
Add JSR223 PostProcessor as a child of the request which returns the above response
Put the following code into "Script" area:
new groovy.json.JsonSlurper().parse(prev.getResponseData()).get(0).get('object').get('attributes').get('Vaccination').each { vaccination ->
if (vaccination.get('value').get('Type').get(0).get('value').equals('Bordatella')) {
def expirationDate = vaccination.get('value').get('ExpirationDate').get(0).get('value')
log.info('ExpirationDate: ' + expirationDate)
vars.put('ExpirationDate', expirationDate)
}
}
If everything goes well (your JSON response matches the Groovy code) the ExpirationDate will be:
printed to jmeter.log file
stored as ${ExpirationDate} JMeter Variable
