Get access to a key in Java HttpClient response

New to API's in Java. I'm trying to get a response from an API and print some of it.
My response in the code below prints the whole dictionary, but I want to print just part of it. In the current way, I have no idea how I can get access to the dictionary, as my response is a String and I couldn't find a relevant BodyHandlers method.
How can I do that? Thanks a lot.
This is my code:
HttpRequest urlAnalysisRequest = HttpRequest.newBuilder()
.uri(URI.create("https://www.virustotal.com/api/v3/analyses/....(I put the id here)"))
.header("Accept", "application/json")
.header("x-apikey", "....(I put api key here)")
.method("GET", HttpRequest.BodyPublishers.noBody())
.build();
HttpResponse<String> urlAnalysisResponse;
try {
urlAnalysisResponse = HttpClient.newHttpClient().send(urlAnalysisRequest, HttpResponse.BodyHandlers.ofString());
System.out.println(urlAnalysisResponse.body());
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
This is my response. I'm trying to get "stats":
{
"meta": {
"url_info": {
"url": "http://www.facebook.com/",
"id": "114fb86b9b4e868f8bac2249eb5c444b545f0240c3dadd23312a0bc1622b5488"
}
},
"data": {
"attributes": {
"date": 1641238171,
"status": "completed",
"stats": {
"harmless": 84,
"malicious": 0,
"suspicious": 0,
"undetected": 9,
"timeout": 0
},
..........

The response is written in a format known as JSON. You need a library to parse this. There are a few options; I strongly suggest you go with Jackson.
You can choose to refer to it with string paths, or, you can make a java class that 'matches' this output, e.g:
class VirusTotalResponse {
VTMeta meta;
VTData data;
}
class VTMeta {
VTUrlInfo urlInfo;
}
class VTUrlInfo {
String url;
String id;
}
and so on. With all those classes in place, turn them all into proper classes (use your IDE's various options, or use Project Lombok) and then just ask Jackson to turn that response into an instance of VirusTotalResponse and you'll have a nice shiny java object, you can then just:
int harmless = response.getData().getAttributes().getStats().getHarmless();

You can use ObjectMapper which is library for handling JSON data easily. You can use not only Class for mapping, but also Map.

Spring Cloud Gateway for composite API calls?

I am starting to build a Microservice API Gateway, and I am considering Spring Cloud to help me with the routing. But some calls to the Gateway API will need multiple requests to different services.
Lets say I have 2 services: Order Details Service and Delivery Service. I want to have a Gateway endpoint GET /orders/{orderId} that makes a call to Order Details service and then Delivery Service and combine the two to return full Order details with delivery. Is this possible with the routing of Spring cloud or should I make these by hand using something like RestTemplate to make the calls?

There is an enhancement proposal posted on GitHub to have routes support multiple URIs. So far, there aren't any plans to implement this yet, at least, not according to one of the contributors.

As posted in the Spring Cloud Gateway Github issue mentioned by g00glen00b, until the library develops a Filter for this, I resolved it using the ModifyResponseBodyGatewayFilterFactory in my own custom Filter.
Just in case it's useful for anyone else, I provide the base implementation here (it may need some rework, but it should be enough to make the point).
Simply put, I have a "base" service retrieving something like this:
[
{
"targetEntryId": "624a448cbc728123b47d08c4",
"sections": [
{
"title": "sadasa",
"description": "asda"
}
],
"id": "624a448c45459c4d757869f1"
},
{
"targetEntryId": "624a44e5bc728123b47d08c5",
"sections": [
{
"title": "asda",
"description": null
}
],
"id": "624a44e645459c4d757869f2"
}
]
And I want to enrich these entries with the actual targetEntry data (of course, identified by targetEntryId).
So, I created my Filter based on the ModifyResponseBody one:
/**
* <p>
* Filter to compose a response body with associated data from a second API.
* </p>
*
* #author rozagerardo
*/
#Component
public class ComposeFieldApiGatewayFilterFactory extends
AbstractGatewayFilterFactory<ComposeFieldApiGatewayFilterFactory.Config> {
public ComposeFieldApiGatewayFilterFactory() {
super(Config.class);
}
#Autowired
ModifyResponseBodyGatewayFilterFactory modifyResponseBodyFilter;
ParameterizedTypeReference<List<Map<String, Object>>> jsonType =
new ParameterizedTypeReference<List<Map<String, Object>>>() {
};
#Value("${server.port:9080}")
int aPort;
#Override
public GatewayFilter apply(final Config config) {
return modifyResponseBodyFilter.apply((c) -> {
c.setRewriteFunction(List.class, List.class, (filterExchange, input) -> {
List<Map<String, Object>> castedInput = (List<Map<String, Object>>) input;
// extract base field values (usually ids) and join them in a "," separated string
String baseFieldValues = castedInput.stream()
.map(bodyMap -> (String) bodyMap.get(config.getOriginBaseField()))
.collect(Collectors.joining(","));
// Request to a path managed by the Gateway
WebClient client = WebClient.create();
return client.get()
.uri(UriComponentsBuilder.fromUriString("http://localhost").port(aPort)
.path(config.getTargetGatewayPath())
.queryParam(config.getTargetQueryParam(), baseFieldValues).build().toUri())
.exchangeToMono(response -> response.bodyToMono(jsonType)
.map(targetEntries -> {
// create a Map using the base field values as keys fo easy access
Map<String, Map> targetEntriesMap = targetEntries.stream().collect(
Collectors.toMap(pr -> (String) pr.get("id"), pr -> pr));
// compose the origin body using the requested target entries
return castedInput.stream().map(originEntries -> {
originEntries.put(config.getComposeField(),
targetEntriesMap.get(originEntries.get(config.getOriginBaseField())));
return originEntries;
}).collect(Collectors.toList());
})
);
});
});
}
;
#Override
public List<String> shortcutFieldOrder() {
return Arrays.asList("originBaseField", "targetGatewayPath", "targetQueryParam",
"composeField");
}
/**
* <p>
* Config class to use for AbstractGatewayFilterFactory.
* </p>
*/
public static class Config {
private String originBaseField;
private String targetGatewayPath;
private String targetQueryParam;
private String composeField;
public Config() {
}
// Getters and Setters...
}
}
For completeness, this is the corresponding route setup using my Filter:
spring:
cloud:
gateway:
routes:
# TARGET ENTRIES ROUTES
- id: targetentries_route
uri: ${configs.api.tagetentries.baseURL}
predicates:
- Path=/api/target/entries
- Method=GET
filters:
- RewritePath=/api/target/entries(?<segment>.*), /target-entries-service$\{segment}
# ORIGIN ENTRIES
- id: originentries_route
uri: ${configs.api.originentries.baseURL}
predicates:
- Path=/api/origin/entries**
filters:
- RewritePath=/api/origin/entries(?<segment>.*), /origin-entries-service$\{segment}
- ComposeFieldApi=targetEntryId,/api/target/entries,ids,targetEntry
And with this, my resulting response looks as follows:
[
{
"targetEntryId": "624a448cbc728123b47d08c4",
"sections": [
{
"title": "sadasa",
"description": "asda"
}
],
"id": "624a448c45459c4d757869f1",
"targetEntry": {
"id": "624a448cbc728123b47d08c4",
"targetEntityField": "whatever"
}
},
{
"targetEntryId": "624a44e5bc728123b47d08c5",
"sections": [
{
"title": "asda",
"description": null
}
],
"id": "624a44e645459c4d757869f2",
"targetEntry": {
"id": "624a44e5bc728123b47d08c5",
"targetEntityField": "somethingelse"
}
}
]

apply gson UPPER_CAMEL_CASE for specific sub-json

I have these messages arriving from SQS:
{
"eventID": "zzz",
"eventName": "MODIFY",
"eventVersion": "1.1",
"eventSource": "aws:dynamodb",
"awsRegion": "us-east-1",
"dynamodb": {
"ApproximateCreationDateTime": 1521976320,
"Keys": {
"key_1": {
"S": "yyy"
},
"key_2": {
"S": "xxx"
}
},
"SequenceNumber": "123",
"SizeBytes": 321,
"StreamViewType": "KEYS_ONLY"
},
"eventSourceARN": "arn:aws:dynamodb:us-east-1:eventSourceARN",
"itemType": "myItem"
}
I want to use gson library to convert this json string into a Record object (com.amazonaws.services.dynamodbv2.model.Record) which contains a StreamRecord object (com.amazonaws.services.dynamodbv2.model.StreamRecord) that represents the dynamodb sub json.
problem is that the inner fields of the dynamodb object are PascalCase while the other fields are normal camelCase.
This code:
Gson gson = new GsonBuilder()
//.setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
.create();
String json = <the json from the example above>
Record record = gson.fromJson(json, Record.class);
log.info("record="+record.toString());
StreamRecord dynamodb = record.getDynamodb();
log.info("dynamodb="+dynamodb.toString());
Map<String, AttributeValue> keys = dynamodb.getKeys();
log.info("keys="+keys.toString());
prints this log (UPPER_CAMEL_CASE commented out) :
record={EventID: zzz,EventName: MODIFY,EventVersion: 1.1,EventSource: aws:dynamodb,AwsRegion: us-east-1,Dynamodb: {},}
and then throws Null Pointer exception because the dynamoDb object is empty - because my json string is UPPER_CAMEL_CASE, while in the object its normal camelCase.
I want to apply FieldNamingPolicy.UPPER_CAMEL_CASE only for the dynamodb sub json.
perhaps somehow using FieldNamingStrategy ?
The json is given and I cannot change its schema.
I also can't change the fact that I get it as string.
see AWS API:
https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_streams_Record.html
https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_streams_StreamRecord.html

You seem to want the following naming strategy:
private static final Gson gson = new GsonBuilder()
.setFieldNamingStrategy(field -> {
if ( field.getDeclaringClass() == StreamRecord.class ) {
return FieldNamingPolicy.UPPER_CAMEL_CASE.translateName(field);
}
return FieldNamingPolicy.IDENTITY.translateName(field);
})
.create();
I usually never use naming strategies in favor of the #SerializedName annotation though, just to be more precise when declaring mappings.

Retrofit Put Request for Mlab

Hi I'm trying to send a PUT request using Retrofit that uses $addToSet to my Mlab Server. I can do this using Postman but I'm having trouble doing it using Retrofit.
The collection looks like:
[
{
"_id": {
"$oid": "5abe74bac2ef1603f4045686"
},
"email": "test#gmail.com",
"completedWalks": [
"South Leinster Way"
],
"favWalks": []
}
]
The post man request has the API key, Query, and then $addToSet is passed in the body as so.
And the response is:
I'm trying to do it like this in android.
Retrofit:
#PUT("databases/walks/collections/user")
Call<Update> addCompleted (#Query("apiKey") String apiKey,#Query("q") String Email, #Body Update Query);
My model:
public class Update {
#SerializedName("n")
private String n;
public String getN() {
return n;
}
public Update(String n) {
this.n = n;
}
}
Creating the update object:
String updateComplete = String.format("'$addToSet': {'completedWalks': '%s'}} ", TrailName);
final String query =String.format("{'email': '%s'}",email) ;
final Update queryComplete = new Update(updateComplete);
And the Request:
Call<Update> completeCall = apiService.addCompleted(mlabAPi, query, queryComplete);
completeCall.enqueue(new Callback<Update>() {
#Override
public void onResponse(Call<Update> call, Response<Update> response) {
Toast.makeText(getApplicationContext(),"Walk marked as Complete", Toast.LENGTH_SHORT).show();
}
#Override
public void onFailure(Call<Update> call, Throwable t) {
Log.e(TAG, t.getMessage());
}
});
But this only overwrites whats in the collection and I have:
[
{
"_id": {
"$oid": "5abe74bac2ef1603f4045686"
},
"n": "'$addToSet': {'completedWalks': 'Kerry Head Cycleway'}} "
}
]
Does anyone know where I'm going wrong, should I not be passing $addToSet as a model because it seems to be overwriting all, how do I pass it then?
Thank You.

#Body Update Query -- Retrofit will encode the object passed to this as JSON (assuming you are using the Gson converter, which it appears you are). That is where this "n": "'$addToSet': {'completedWalks': 'Kerry Head Cycleway'}} " is coming from. You need to structure you Java Object the same as your JSON object for gson to serialize it correctly.
I am not familiar with the mlab api, but from your postman, it looks like you want a request body something like this --
public class UpdateRequest {
#SerializedName("$addToSet")
Map<String, String> addToSet = new HashMap();
}
Update your interface to send this object as the body --
#PUT("databases/walks/collections/user")
Call<Update> addCompleted (#Query("apiKey") String apiKey,#Query("q") String Email, #Body UpdateRequest Query);
And create the request body --
UpdateRequest requestBody = new UpdateRequest();
requestBody.addToSet.put("completedWalks", Trailname);
and create the call --
Call<Update> completeCall = apiService.addCompleted(mlabAPi, query, requestBody);
For further debugging, you can see what is actually being sent in your logcat by adding HttpLoggingInterceptor to your retrofit instance.
See here for setup. Then you can compare what your app is sending vs postman and see where things might be going sideways.

GSON Expected BEGIN_ARRAY but was BEGIN_OBJECT

I'm getting this error when I receive only one single item in a list. I'm using Jersey in the server side REST Web service, I only get the error when the List returned one single element and when it has 0 elements I get java.lang.NullPointerException But when it has more than one it works perfectly, and this is how I'm doing it :
#GET
#Path("getproject")
#Produces(MediaType.APPLICATION_JSON)
public List<Project> getPagedProjects(
#QueryParam("offset") int offset,
#QueryParam("limit") int limit,
#QueryParam("searchKey") String searchKey) throws Exception {
System.out.println("Returning Paged Project ");
return projectService.getPagedProjects(offset, limit, searchKey);
}
Why doesn't Jersey send a list that contains one single item? It is a bug in jersey?
Is there a way to make it always serialize as an array?
This is my JSON data when the web service returns 0 element:
null
And This is my JSON data when web service returns 1 element :

And in android side I deserialize the JSON response like this :
Gson gson = new Gson();
final ProjectContainer container = gson.fromJson(resultat, ProjectContainer.class);
final ListView lv = (ListView) findViewById(R.id.list);
adaptateur = new ProjectAdapter(ProjectActivity.this, R.layout.ligne_project, container);
lv.setAdapter(adaptateur);
This is my ProjectContainer class :
public class ProjectContainer {
#SerializedName("project")
List<Project> projects ;
public List<Project> getProjects() {
return projects;
}
public void setProjects(List<Project> projects) {
this.projects = projects;
}
}
I would greatly appreciate your help to solve this problem. Thanks in advance

Your issue results really weird for me... it seems that there must be some problem with Jersey's JSON serialization of single element arrays... if you Google "Jersey JSON single element arrays" you'll find the same issue, like here or here. I don't know too much about Jersey, so I can't help you with that...
That said, I can suggest a workaround using manually parsing in Gson, to adapt your parsing to the 2 different responses (object or array). You could do something like this:
//manually parsing until get the "project" element...
JsonParser parser = new JsonParser();
JsonObject rootObejct = parser.parse(yourJsonString).getAsJsonObject();
JsonElement projectElement = rootObejct.get("project");
Gson gson = new Gson();
List<Project> projectList = new ArrayList<>();
//Check if "project" element is an array or an object and parse accordingly...
if (projectElement.isJsonObject()) {
//The returned list has only 1 element
Project project = gson.fromJson(projectElement, Project.class);
projectList.add(project);
}
else if (projectElement.isJsonArray()) {
//The returned list has >1 elements
Type projectListType = new TypeToken<List<Project>>() {}.getType();
projectList = gson.fromJson(projectElement, projectListType);
}
//Now you have a List<Project> projectList with one or many Project elements,
//depending on the response...
Note that you don't need your class ProjectContainer.
Something like this should work for you, although obviously the best thing would be fix the serialization issue!

Basically, your web service is broken in terms of how it's replying. If there's only one object for project it's returning only an object instead of an array.
MikO's answer solves the problem but another approach is encapsulating that logic in a custom deserializer:
class MyDeserializer implements JsonDeserializer<ProjectContainer> {
#Override
public ProjectContainer deserialize(JsonElement je, Type type, JsonDeserializationContext jdc) throws JsonParseException {
JsonObject jo = je.getAsJsonObject().getAsJsonObject("project");
if (jo.isJsonArray()) {
return new Gson().fromJson(je, ProjectContainer.class);
} else {
Project p = jdc.deserialize(jo, Project.class);
List<Project> pList = new ArrayList<Project>(1);
pList.add(p);
ProjectContainer pc = new ProjectContainer();
pc.setProjects(pList);
return pc;
}
}
}
Then you can use:
Gson gson = new GsonBuilder()
.registerTypeAdapter(ProjectContainer.class, new MyDeserializer())
.build();
ProjectContainer pContainer = gson.fromJson(myJson, ProjectContainer.class);

I ended up using Jackson library instead of gson to parse the json response. It automatically converts object into ArrayList. It is pretty much similar to gson in terms of ease of use. Hope it helps!
