Iterate through two loops when building the JSON String - json

Question

I am invoking a restful service to get the available documents on the the server where I am getting the JSON as s response. I am building the JSON String with the JSONBuilder so when invoking the this link
http://localhost:8080/httpConnector/Rest/Documents?Accept=application/json
I am getting the JSON String below:
{
"results": [
{
"result": {
"name": "Test traisy",
"version": "sdvdsv",
"author": "sdvdsv"
}
},
{
"result": {
"name": "Jaspersoft Ultimate guide",
"version": "sdfdsv",
"author": "sdvdsv"
}
},
{
"result": {
"name": "Dohrn",
"version": "12.19.00",
"author": "sdfdsf"
}
}
]
}
Code
String accept = getValue("Accept");
accept = "application/xml";
if ("application/xml".equals(accept)){
builder=new groovy.xml.MarkupBuilder(writer);
}else{
builder=new groovy.json.JsonBuilder();
}
builder{
results foaList.collect{
[
//Here I want to loop through the otaList to do something like that "ota.getName(), foa.getFlexiObject().getByString(ota.getName())"
result: [
name: it.getFlexiObject().getByString("name"),
version: it.getFlexiObject().getByString("version"),
author: it.getFlexiObject().getByString("author")
]
]
}
}
Now I want to add the properties programatically. Therefore I have to loop through the otaList to do something like that
builder.'results'() {
for(FlexiObjectAttachment foa: foaList){
for(ObjectTypeAttribute ota : otaList){
param.put(ota.getName(), foa.getFlexiObject().getByString(ota.getName()));
}
result(param);
}
}
this version just works for the xml respose.

Answer 1

What you can try is to do the combination of foa and ota directly in your collect call.
That way your initially created dict would have the correct structure.
Something like the example below
def foaList = [1, 2, 3, 4]
def otaList = ['A', 'B', 'C']
foaList.collect { foa ->
result = [name: "Name$foa", version: "v$foa", author: "Author$foa"]
otaList.each { ota -> result[ota] = "$ota$foa" }
[ result: result ]
}
