How to form post request body where resource contained multi reference resources from Java to FHIR api

I have to send request body as org.hl7.fhir.r4.model.CoverageEligibilityRequest which is contained Patient, Practitioner, Organization as below. This API will return Bundle response. I am using Java and Generic client from Hapi Fire library. There is provision to pass search parameter but the here I am having multilevel hierarchy of resource and input is big than usual. Can any one help me to handle this request in FHIR API.
Request Body as below,
{
"resourceType": "CoverageEligibilityRequest",
"contained": [
{
"resourceType": "Patient",
"id": "1",
"name": [
{
"family": "abcFamily",
"given": [
"abcGiven"
]
}
],
"birthDate": "1962-08-06"
},
{
"resourceType": "Practitioner",
"id": "2",
"identifier": [
{
"type": {
"coding": [
{
"code": "NPI"
}
]
},
"value": "123456789"
}
],
"name": [
{
"family": "pqrFamily",
"given": [
"pqrGiven"
]
}
]
},
{
"resourceType": "Organization",

}
],

}
],

Apache Velocity: remove key/value from json

I have a JSON
{
"Id": "xxx",
"Type": "Transaction.Create",
"Payload": {
"result": 2,
"description": "Pending",
"body": {
"redirect": {
"url": "xxx",
"fields": {
"MD": "8a829449620619e80162252adeb66a39"
}
},
"card": {
"expiryMonth": "1",
"expiryYear": "2033"
},
"order": {
"amount": 1
}
}
}
}
And I want to remove the card info of it like this:
{
"Id": "xxx",
"Type": "Transaction.Create",
"Payload": {
"result": 2,
"description": "Pending",
"body": {
"redirect": {
"url": "xxx",
"fields": {
"MD": "8a829449620619e80162252adeb66a39"
}
},
"order": {
"amount": 1
}
}
}
}
How can I do this with Apache velocity?
What works is:
#set($content = $util.urlEncode($input.json('$')))
#set($new = $content.replaceAll("2033","2055"))
Action=SendMessage&MessageBody={"body": "$new","Event-Signature": "$util.urlEncode($input.params('Event-Signature'))"}
This gives me
{
"Id": "xxx",
"Type": "Transaction.Create",
"Payload": {
"result": 2,
"description": "Pending",
"body": {
"redirect": {
"url": "xxx",
"fields": {
"MD": "8a829449620619e80162252adeb66a39"
}
},
"card": {
"expiryMonth": "1",
"expiryYear": "2050"
},
"order": {
"amount": 1
}
}
}
}
But now I want to remove the card part but it does not work:
#set($content = $util.urlEncode($input.json('$')))
#set($new = $content.delete("$.Payload.body.card"))
Action=SendMessage&MessageBody={"body": "$new","Event-Signature": "$util.urlEncode($input.params('Event-Signature'))"}
what am I doing wrong?
Main goal is transform a mapping template in API Gateway for a webhook. The webhook contains to many information and we want to remove some part of the JSON POST call.

Try using the below
#set($dummy=$content.Payload.remove("card"))

Groovy remove from map

The list below contains a collection of id's
List id_wanted = ['3894586', '2786438236', '895673985']
Given the list above, How do I remove elements from the JSON below that match with the id above List?
JSON:
{
"animals": [
{
"name": "lion",
"countries": [
{
"name": "kenya",
"facts": [
{
"features": [
"young male"
],
"age": "2y",
"id": "2837492"
}
]
},
{
"name": "tanzania",
"facts": [
{
"features": [
"cub"
],
"age": "0y",
"id": "3894586"
}
]
},
{
"name": "south africa",
"facts": [

],

},
{
"features": [
"young female"
],
"age": "4y",
"id": "2786438236"
}
]
}
]
},
{
"name": "giraffe",
"countries": [
{
"name": "zambia",
"facts": [
{
"features": [

}
]
},
{
"name": "kenya",
"facts": [
{
"features": [
"male"
],
"age": "17y",
"id": "85604586"
}
]
},
{
"name": "uganda",
"facts": [
{
"features": [
"young female"
],
"age": "4y",

},
{
"features": [
"none"
],
"age": "11y",
"id": "39860394758936764"
}
]
}
]
}
]
}
For example, the following block would be removed from the JSON above because id matches with the List id_wanted
{
"features": [
"young female"
],
"age": "4y",
"id": "2786438236"
}

Assuming your json is a String in a variable inputJson, it's probably easier to build a new Json document from the original with those values filtered out:
import groovy.json.*
def json = new JsonSlurper().parseText(inputJson)
List id_wanted = ['3894586', '2786438236', '895673985']
def result = new JsonBuilder([
animals: json.animals.collect {[
name: "$it.name",
countries: it.countries.collect { [
name: "$it.name",
facts: it.facts.findAll { !(it.id in id_wanted) }
]}
]}
]).toString()

You can parse your original json and modify the resulted data structure in-place using handy *. spread operator:
def json = slurper.parseText(original)
json.animals*.countries*.facts*.each { facts ->
facts.removeAll { fact -> fact.id in id_wanted }
}
def filtered = new JsonBuilder(json).toPrettyString()
println(filtered)
Output (with facts from id_wanted removed):
{
"animals": [
{
"name": "lion",
"countries": [
{
"name": "kenya",
"facts": [
{
"features": [
"young male"
],
"age": "2y",
"id": "2837492"
}
]
},
{
"name": "tanzania",
"facts": [
]
},
{
"name": "south africa",
"facts": [
{
"features": [
"adult lioness"
],
"age": "10y",
"id": "495684576"
}
]
}
]
},
{
"name": "giraffe",
"countries": [
{
"name": "zambia",
"facts": [
{
"features": [
"ex captivity"
],
"age": "20y",
"id": "343453509"
}
]
},
{
"name": "kenya",
"facts": [
{
"features": [

],

Am using gson-2.2.4.jar

I'm guessing you mean by not writing your own bean for GSON to deserialize to. GSON provides support by having certain JSON types that you can make use of:
Gson gson = new Gson();
final JsonArray jsonElements = gson.fromJson(JSON, JsonArray.class);

Assuming obj is a JSONObject obtained by parsing the posted String
"results" is the key to a JSONArray that you get from your object using
JSONArray results = obj.getJSONObject("d").getJSONArray("results")
JSONArray has get*(int index) for each type of data you can encounter.
In your case, "results" is an array of JSONObject. You can loop through it using :
for (int i = 0; i < results.length(); i++) {
JSONObject oneResult = results.getJSONObject(i);
}
Once you have the JSONObject, the MediaUrl is just one getString("MediaUrl") away ...
