Starting from the similar question,
Nested JSON Array in Java
I have a somewhat odd json as a response from a REST api(POST) call. I need to find out the id and name of the sub_items array in each items array element.
I tried like given below for which I am getting error like
org.json.JSONException: JSONObject["items.sub_items"] not found.
I also tried just 'sub_items' as the parameter also, but no. I am using GSON. No choice use others.
final JSONObject jsonObj = new JSONObject(JSON_STRING);
final JSONArray subItems = jsonObj.getJSONArray("items.sub_items");
final int n = subItems.length();
for (int i = 0; i < n; ++i) {
final JSONObject subI= subItems.getJSONObject(i);
System.out.println("id="+subI.getString("id"));
System.out.println("name="+subI.getString("name"));
}
The following is my json as a response from a REST api call.
{
"menu": {
"items": [{
"id": 1,
"code": "hot1_sub1_mnu",
"name": "Mutton",
"status": "1",
"sub_items": [{
"id": "01",
"name": "Mutton Pepper Fry",
"price": "100"
}, {
"id": "02",
"name": "Mutton Curry",
"price": "100"
}]
},
{
"id": "2",
"code": "hot1_sub2_mnu",
"name": "Sea Food",
"status": "1",
"sub_items": [{
"id": "01",
"name": "Fish Fry",
"price": "150"
}]
},
{
"id": "3",
"code": "hot1_sub3_mnu",
"name": "Noodles",
"status": "1",
"sub_items": [{
"id": "01",
"name": "Chicken Noodles",
"price": "70"
}, {
"id": "02",
"name": "Egg Noodles",
"price": "60"
}]
}
]
}}
As I said, my JSON is a response from an REST api call, and it is 7300 lines long, like shown below with the outline, as shown in code beautifier.
object {3}
infoTransferReqResp {1}
paramExtens : null
pageGroups {1}
pageGroups [1]
0 {4}
page_group_name : LFG - LG - Insured Summary
page_group_id : 8100
**pages [3]**
repeatingBlocks {1}
I needed to extract a string value 'questionText' from inside 'Pages' array. I used jsonPath() method with navigation path as given below which solved the problem.
JsonPath jsonPathEvaluator = response.jsonPath();
List<List<List<String>>> questions = jsonPathEvaluator.getList("pageGroups.pageGroups.pages.questions.questionText");
It gave me 3 ArrayLists one embedded in another corresponding to 3 arrays of 'pages'

How to get a new list from the list of objects?
I need a new list of objects to POST request
this list of objects i get from response:
{
"success": true,
"body": {
"users": [
{
"type": "unknown",
"data": [
{
"id": "8",
"firstName": "Jackson",
"lastName": "Baker",
"group": "false"
},
{
"id": "11",
"firstName": "Charlotte",
"lastName": "Garcia",

{
"id": "7",
"firstName": "Henry",
"lastName": "Thompson",
"group": "false"
},
{
"id": "24",
"firstName": "Elijah",
"lastName": "Miller",
"group": "false"
}
]
}
]
}
}
I need to form a new object from response:
{
"success": true,
"body": {
"users": [
{
"type": "unknown",
"data": [
{
"id": "8",
"group": "false"
},
{
"id": "11",
"group": "false"
},
{
"id": "7",
"group": "false"
},
{
"id": "24",
"group": "false"
}
]
}
]
}
}
This new list of object I need to post a request.
I have a JSON Schema, but i don't know how i can make this structure.
My problem is that I can't get the values from fields. I'm using the path "body.users.data.find {it.id} .id" but it finds the id array but I need a users list with values from two fields.
As the users node and data node are all list type, you need use two loop:
import groovy.json.JsonSlurper
// text is your json response text
def result = new JsonSlurper().parseText(text)
result.body.users.each{it.data.each{it.remove("firstName");it.remove("lastName")}}
// result is the what you wanted
println(result)
I am using jsonpath to filter.
Json(Dummy json just to explain) source String, which is basically a list of Operating systems and details of its programs etc. In this example, the OS whose id = 1403 is a windows 10 OS and has 2 features acchritecture and browser. There are more details to the browser feature as shown in json
[
{
"id": 1403,
"os": "window 10",
"features": [
{
"id": 1356,
"name": "architecture",
"value": [
{
"id": 1308,
"feature": [
{
"id": 1262,
"key": "name",
"value": "amd64"
}
]
}
],
"category": "cat1"
},
{
"id": 1357,
"name": "browser",
"value": [
{
"id": 1309,
"feature": [
{
"id": 1263,
"key": "name",
"value": "Firefox"
},
{
"id": 1265,
"key": "version",
"value": "187"
}
]
}
],
"category": "cat2"
}
]
},
{
"id": 2804,
"os": "window 7",
"features": [
{
"id": 2764,
"name": "architecture",
"value": [
{
"id": 2719,
"feature": [
{
"id": 2679,
"key": "name",
"value": "amd64"
}
]
}
],
"category": "cat1"
},
{
"id": 2765,
"name": "browser",
"value": [
{
"id": 2722,
"feature": [
{
"id": 2685,
"key": "name",
"value": "Chrome"
},
{
"id": 2684,
"key": "version",
"value": "87.0.4280.88"
}
]
}
],
"category": "cat2"
}
]
}
]
I want to be able to filter the json such that
features[*].name == 'browser' and features[*].value[*].feature[*].value == 'chrome'
What will be the JsonPath string that can help me achieve above query? The above query uses similar syntax used by JsonPath string but doesn't do the job. Its just to explain.
There is another example here gets Movie Title Given 'Starring' field
And would like to get the full OS json that fulfils this condition. In this case a array of OS which contains only one OS i.e. with id= 2804
[
{
"id": "2804",
...
}
]
I am stuck much before what aim to achieve. Here is my code to get all the OS that have "name=browser". I get the array but it only contains value[] items. I want it get the full json. It returns object with IDs- 1357, 2765.
List<Map<String, Object>> expensive = JsonPath.parse(jsonDataSourceString)
.read("$[*].features[*].[?(#.name == 'browser')]");
To get the outer array you need to use the filter like $[?(...)]
For your current use case, we need to use nested array filters. There is an open issue in JsonPath for filter on children level. (Refer here).
Luckily, there is a workaround suggested to use contains over here.
we can use the below expression to filter:
List<Object> expensive = JsonPath.parse(jsonDataSourceString)
.read("$[?(#.features[?(#.name == 'browser')].value[*].feature[*].value contains 'Chrome')]");
Prints the below output
{id=2804, os=window 7, features=[{"id":2764,"name":"architecture","value":[{"id":2719,"feature":[{"id":2679,"key":"name","value":"amd64"}]}],"category":"cat1"},{"id":2765,"name":"browser","value":[{"id":2722,"feature":[{"id":2685,"key":"name","value":"Chrome"},{"id":2684,"key":"version","value":"87.0.4280.88"}]}],"category":"cat2"}]}
I have a json response something like this:
"results": [
{
"id": "1",
"name": "YYY",
"shortName": "Y"
},
{
"id": "2",
"name": "XXX",
"shortName": "X"
},
{
"id": "3",
"name": "ZZZ",
"shortName": "Z"
}
]
I want to get id value when I send name value. For example if name = ZZZ return me id value in this case 3 using rest assured
Json path json-path-2.9.0 with rest-assured
import static com.jayway.restassured.path.json.JsonPath.from;
below JsonPath query
from(response).getList("results.findAll { it.name=='ZZZ' }.id").toString() //returns 3
from(response).getList("results.findAll { it.name=='XXX' }.id").toString() //returns 2

I want to load three attributes into my table ( id, actions_name and actions_link). So, in the first step (tFileInputJSON) - I tried to do a Loop Json query as below:
Here, am able to extract the rows as I needed. But, then I used a tExtractJSONField to extract individual fields under "actions" for each "id" using XPath expressions as below:
I tried several other ways to extract the fields but could not do this. Also, not able to find any correct post in stack overflow and talent forums very relevant to my question. Could somebody please help?
Arrange the job like ,
tFileInputJSON is like,
tExtractJSONFields is like,
Then you will get output as,
I have a json something like this below .I want to read it and add 2 more attribute ti it like country and state
[
{
"id": "123",
"testname": "test123",
"name": "John Doe",
"active": true,
"type": "test6"
}
{
"id": "456",
"testname": "test564",
"name": "Ship Therasus",
"active": true,
"type": "test7"
}
]
Resulting json
[
{
"id": "123",
"testname": "test123",
"name": "John Doe",
"active": true,
"type": "test6",
"country":"USA",
"state":"KA"
}
{
"id": "456",
"testname": "test564",
"name": "Ship Therasus",
"active": true,
"type": "test7",
"country":"UK",
"state":"MA"
}
]
I am doing something like this I tried JSONObject but no output.
JSONArray xmlJSONObj2 = new JSONArray(output);
System.out.println("Output from Server .... \n"+xmlJSONObj2.get(0));
you can use for loop to iterate over JSONArray, Once you have jsonObject use put for extra attribute like this
for(int i=0;i<jsonArray.length();i++){
JSONObject json = jsonArray.getJSONObject(i);
// do this for all remaining field
if(json.has("id")){
String id = json.get("id").toString();
}
// finally put extra attributes to that jsonobject
json.put("country", "USA");
json.put("state", "KA")
}
missed commas after "type":"test6"
{
"id": "123",
"testname": "test123",
"name": "John Doe",
"active": true,
"type": "test6" <------
"country":"USA",
"state":"KA"
}
