Adding responses as elements ,to an array in json response
Input request :
[
{
"id" : "1",
"make" : "TAHB",
"children":[
{
"kid":"1"
},
{
"kid":"2"
}
]
},
{
"id" : "2",
"make" : "Tonda"
},
{
"id" : "3",
"make" : "Tamsung"
}
]
I am using iterate, to send each element of above array as request to a
backend service( In myactual project this is not so simple service i.e.
backend service reponse is very complex json with lots of arrays and
sub-arrays(child arrays)in it . for better understanding of issue I kept it
like this ).
The responses of the backend service are aggregated in one soap xml by
AggregateMediator.
Below is response from AggregateMediator
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";>
<soapenv:Body>
<Information>
<jsonObject>
<id>1</id>
<make>TAHB</make>
<children>
<kid>1</kid>
</children>
<children>
<kid>2</kid>
</children>
<name>Home</name>
<area>5000sqft</area>
</jsonObject>
<jsonObject>
<id>2</id>
<make>Tonda</make>
<name>Car</name>
<model>Tmaze</model>
</jsonObject>
<jsonObject>
<id>3</id>
<make>Tamsung</make>
<name>Mobile</name>
<model>S8</model>
</jsonObject>
</Information>
</soapenv:Body>
</soapenv:Envelope>
Requirement is to add all the responses from the backend service except the
first one, to the child array of the first response of the backend service.
I do not know how to do this ? not even how to add new elements to a array
in wso2.
My Current Output :
{
"id": 1,
"make": "TAHB",
"children": [{
"kid": 1
},
{
"kid": 2
}],
"name": "Home",
"area": "5000sqft",
"jsonObject": [{
"id": 2,
"make": "Tonda",
"name": "Car",
"model": "Tmaze"
},
{
"id": 3,
"make": "Tamsung",
"name": "Mobile",
"model": "S8"
}]
}
Desired Output :
{
"id": 1,
"make": "TAHB",
"children": [
{
"kid": 1
},
{
"kid": 2
},
{
"id": 2,
"make": "Tonda",
"name": "Car",
"model": "Tmaze"
},
{
"id": 3,
"make": "Tamsung",
"name": "Mobile",
"model": "S8"
}
],
"name": "Home",
"area": "5000sqft",
}
Please find main xml and backendService xml attached. It contains what I
tried.
main xml : addChild.xml
backendService xml : modifyAgrRes.xml
