Iterate last values present in a JSON response using java - java

I need to iterate and get the last values like name, url and color from below JSON response. Using java/gson api. Please help me on this.
{
"Title": {
"desc": [
{
"name": "PRE_DB",
"url": "http://jenkins.example.com/job/my_first_job/",
"color": "blue_anime"
},
{
"name": "SDD_Seller_Dashboard",
"url": "http://jenkins.example.com/job/my_second_job/",
"color": "blue_anime"
}
]
}
}
example output :
name : SDD_Seller_Dashboard
color :blue_anime


JSONObject data = new JSONObject(your_JSON_Repsonse);
JSONArray data_desc=data.getJSONArray(desc);
for(int i=0;i<=data_desc.length();i++)
{
name=data_desc.getString("name");
url=data_desc.getString("url");
color=data_desc.getString("color");

How to remove an attribute from RequestSpecification/FilterableRequestSpecification body?

Dears,
I am working on creating a simple method which will take String argument which will be a path or other kind "pointer" to attribute/s in JSON and this method will remove those attribute/s.
My problem is I can find values of those attribute/s using JsonPath, but I can't find methods in rest assured (or other libraries) which could remove/delete attributes by given path.
JSON is already added earlier so i need to pull him from RequestSpecification or FilterableRequestSpecification object ex.
RequestSpecification rs = *objFromContext*;
FilterableRequestSpecification frs= (FilterableRequestSpecification) rs;
frs.getBody();
I've tried to work with JSONObject class and remove() but it doesn't work on complex JSONs.
given example JSON
{
"created": "string",
"updated": "string",
"items": [
{
"code": "TEST",
"nested": {
"code": "test",
"name": "name",
"other": [
{
"code": "TEST",
"name": "myName",
"quantity": 1
}
]
},
"itemsProperties": [
{
"code": "value1",
"name": "name",
"value": 123
}
]
},
{
"code": "TEST",
"nested": {
"code": "test",
"name": "name",
"other": [
{
"code": "TEST",
"name": "myName",
"quantity": 1
}
]
},
"itemsProperties": [
{
"code": "value2",
"name": "name",
"value": 123
}
]
}
],
"timer": {
"startDate": "2015-01-01",
"endDate": "2021-01-02"
},
"id": "myId"
}
using JsonPath jp = JsonPath.from(httpRequest.getBody().toString());
and then jp.get(items.itemsproperties.code) i can find value1 and value2.
I stuck in this point: How to remove those attributes from sended body?
I know i can convert body into JSONObject and then go field after field conversion between getJSONArray and GetJSONOBject and remove those fields, but i would like to make this metod much more universal.
Is this possible?

If you want to manipulate json in Rest-Assured JsonPath, then the answer is No. You can't do that. JsonPath help you to extract value from json, that's it, no more.
You have to use different libraries to remove key-value pair.
For example: using JsonPath Jayway
DocumentContext parse = JsonPath.parse(body);
parse.delete("$..itemsProperties..code");
System.out.println(parse.jsonString());

How to assign to a new array an array of objects?

I can't figure out how I would do the ff.
I have the ff. Payload
{
"code": null,
"message": null,
"recCtrlOut": {
},
"acctSumm": [
{
"acctBasic": {
"acctType": "SV",
"acctId": "123",
},
"acctBasic": {
"acctType": "SV",
"acctId": "321",
}
}
]
}
And I just want to get the acctId params and assign it to a new plain array of accountIds. How do I do it in Spring/Java?. Thanks

Try using json path. Library can be found here. E.g. say you had json like this:
{
"code": null,
"message": null,
"recCtrlOut": {
},
"acctSumm": [
{
"acctBasic": {
"acctType": "SV",
"acctId": "123"
}
},
{
"acctBasic": {
"acctType": "SV",
"acctId": "321"
}
}
]
}
Actual code would be something like:
List<String> ids = JsonPath.read(json, "$.acctSumm[*].acctBasic.acctId");
The above list will now hold:
["123","321"]
If you wanna learn json path syntax, you could try using this online tool. Here is also a guide to help you get started with json path.

Get values out of JSON (Map<String, Object>) with JSONObject

Is it possible to get all the values (linkID,text,options) out of JSON example below (as a String result let's say) using JSONObject, JSONArray, getString() (org.json) library in Java? If yes, can someone please give an example.
"items": [
{
"linkID": "my/link1",
"text": "Some text 1.",
"options": [
"yes",
"no",
"maybe",
"always"
]
},
{
"linkID": "my/link2",
"text": "Some text 2.",
"options": [
"yes",
"no",
"maybe",
"always"
]
}
]
UPDATE:
I found a solution for example above. If there is a better one please tell.
JSONArray items = json.getJSONArray("items");
for (int i = 0; i < items.length(); ++i) {
JSONObject rec = items.getJSONObject(i);
String linkID = rec.getString("linkID");
System.out.println(linkID);
String text = rec.getString("text");
System.out.println(text);
JSONArray options = rec.getJSONArray("options");
System.out.println(options);
}
And can I get inner code that has value 61377 in example below if I have 2 keys with the same names code in JSON payload?
"code": {
"code": "61377",
"result": "ok"
"info": "Some text"
},

Yes, You can get the value of the inner field code by doing this,
jsonObject.optJSONObject("code").optString("code")
Where jsonObject is,
"code": {
"code": "61377",
"result": "ok"
"info": "Some text"
},

mongodb query to find value in json

I started working with MongoDB. I prepared some basic training JSON:
{
"header": {
"Hotel": {
"data": [
{
"name": "Hilton",
"Id": "1231213421"
}
]
},
"standard": "5",
"priceStage": "4"
},
"data": {
"http": {
"strean": {}
}
}
}
and I wrote a query like this:
db.hotel.find( "data": { Id: "1231213421"})
Why query does not return anything?

You're trying to match on an element within an array and you don't need to match on the entire array. So,something like the following will work:
db.hotel.find({"header.Hotel.data": {"$elemMatch": {"Id": "1231213421"}}} );

The sum of several items in a json

I have a JSON source with more empty_slots elements (in the example exist below only one, but in the reality exist more stations with empty_slots). How can I sum the values from empty_slots and return as double? Thanks!
JAVA
public static double getValueFromJSONString(String jString) throws JSONException
{
JSONObject json = new JSONObject(jString);
return json.getJSONObject("empty_bikes").getDouble(jString);
}
JSON
{"network": {
"company": [
"Gewista Werbegesellschaft m.b.H"
],
"id": "citybike-wien",
"location": {
"city": "Wien",
},
"stations": [
{
"empty_slots": 3,
"extra": {
"slots": "26",
},
"free_bikes": 23
}]}

Checkout JsonPath. Below code is not tested but should work with RestAssured dependency - https://github.com/rest-assured/rest-assured
JsonPath jsonPath = new JsonPath(jsonString);
List<Integer> companyEntityIds = jsonPath.getList("network.stations.empty_slots");
Once you have the array you can just use a stream or whatever to add these up.
