In my application, we have a method that accepts JSON and path which tell us which object we need to get from that JSON. Buth both JSON and path are dynamic, I can't predict that every time we get a request we are getting the same JSON and path.
Example:
{
"company": {
"employees": {
"employee": {
"department": {
"departmentId": 1,
"departmentName": "Developer"
},
"employeeDetails": {
"id": 1,
"name": "abc"
}
}
}
}
}
and the path is company.employees.employee.department. And the requirement is when I get this path I only need that nested JSON object with employee details. Expected output:{
"company": {
"employees": {
"employee": {
"department": {
"departmentId": 1,
"departmentName": "Developer"
}
}
}
}
}
I am confused about your requirement. There is ambiguity in your question. I am thinking that you want to access employeeDetails from the JSON. Here is the solution for that:
var data = {
"company": {
"employees": {
"employee": {
"department": {
"departmentId": 1,
"departmentName": "Developer"
},
"employeeDetails": {
"id": 1,
"name": "abc"
}
}
}
}
}
var employee = data.company.employees.employee // this will store the nested json which is having employeeDetails
console.log(employee)// nested JSON with employeeDetails
console.log(employee.employeeDetails)// this will give you the employeeDetails
The method may look like:
const getData = (json, path) => {
let current = json;
const keys = path.split('.');
for (let key of keys) {
if (!current) {
break;
}
current = current[key];
}
return current;
};
getData(yourJSON, 'key1.key2.key3');
I have data that looks like this:
{
"status": "success",
"data": {
"irrelevant": {
"serialNumber": "XYZ",
"version": "4.6"
},
"data": {
"lib": {
"files": [
"data1",
"data2",
"data3",
"data4"
],
"another file": [
"file.jar",
"lib.jar"
],
"dirs": []
},
"jvm": {
"maxHeap": 10,
"maxPermSize": "12"
},
"serverId": "134",
"version": "2.3"
}
}
}
Here is the function I'm using to prettify the JSON data:
public static String stringify(Object o, int space) {
ObjectMapper mapper = new ObjectMapper();
try {
return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(o);
} catch (Exception e) {
return null;
}
}
I am using the Jackson JSON Processor to format JSON data into a String.
For some reason the JSON format is not in the format that I need. When passing the data to that function, the format I'm getting is this:
{
"status": "success",
"data": {
"irrelevant": {
"serialNumber": "XYZ",
"version": "4.6"
},
"another data": {
"lib": {
"files": [ "data1", "data2", "data3", "data4" ],
"another file": [ "file.jar", "lib.jar" ],
"dirs": []
},
"jvm": {
"maxHeap": 10,
"maxPermSize": "12"
},
"serverId": "134",
"version": "2.3"
}
}
}
As you can see under the "another data" object, the arrays are displayed as one whole line instead of a new line for each item in the array. I'm not sure how to modify my stringify function for it to format the JSON data correctly.
You should check how DefaultPrettyPrinter looks like. Really interesting in this class is the _arrayIndenter property. The default value for this property is FixedSpaceIndenter class. You should change it with Lf2SpacesIndenter class.
Your method should looks like this:
public static String stringify(Object o) {
try {
ObjectMapper mapper = new ObjectMapper();
DefaultPrettyPrinter printer = new DefaultPrettyPrinter();
printer.indentArraysWith(new Lf2SpacesIndenter());
return mapper.writer(printer).writeValueAsString(o);
} catch (Exception e) {
return null;
}
}
I don't have enough reputation to add the comment, but referring to the above answer Lf2SpacesIndenter is removed from the newer Jackson's API (2.7 and up), so instead use:
printer.indentArraysWith(DefaultIndenter.SYSTEM_LINEFEED_INSTANCE);

hello I'm trying t get the distance from a JSON object
{
"destination_addresses": [
"Rabat, Morocco"
],
"origin_addresses": [
"Marrakesh, Morocco"
],
"rows": [
{
"elements": [
{
"distance": {
"text": "324 km",
"value": 323624
},
"duration": {
"text": "3 hours 24 mins",
"value": 12233
},
"status": "OK"
}
]
}
],
"status": "OK"
}
I succeeded to get the elements object but I can't get the distance
org.json.JSONException: No value for distance
at org.json.JSONObject.get(JSONObject.java:389)
at com.application.zarbagaskazay.colivoiturage.testMApsActivity$1.onResponse(testMApsActivity.java:66)
at com.application.zarbagaskazay.colivoiturage.testMApsActivity$1.onResponse(testMApsActivity.java:56)
at com.android.volley.toolbox.JsonRequest.deliverResponse(JsonRequest.java:65)
here is the code
public void onResponse(JSONObject response) {
try {
JSONArray rows = response.getJSONArray("rows");
JSONObject elements=rows.getJSONObject(0);
// JSONObject cc= elements.getJSONObject("distance");
System.out.println(elements.get("distance"));
button.setText(elements.get("distance").toString());
} catch (JSONException e) {
e.printStackTrace();
}
In my suggestion:
You can replace
System.out.println(elements.get("distance"));
with
System.out.println(elements.getJSONArray("elements").getJSONObject(0).getJSONObj
ect("distance"));
Above sop will print/extract "distance" json value.
{"text":"324 km","value":323624}
Hope it works at your end too!
JSONObject jsonObject = new JSONObject("YOUR RESPONSE STRING");
JSONArray jsonArray = jsonObject.getJsonArray("rows");
JSONArray jsonArray_elements =jsonArray.getJsonObject(0).getJsonArray("elements");
JSONObject jsonObject_distance =
jsonArray_elements.get(0).getJsonObject("distance");
String text = jsonObject_distance.getString("text");
String value = jsonObject_distance.getString("value");
I am converting JSONObject to String. I am using below code:
String decresponse=obj.getFileWithUtil("Files/v3user22.txt");
System.out.println("Decrypted string is "+decresponse);
JSONObject js = JSONObject(decresponse);
System.out.println("JSON Object is "+js.toString());
Here, i am getting the value of decresponse from a file since the json is very large. Value of decresponse is:

Why am I getting different values?
Why am I getting different values
Those values are not that different. They simply have key:value pairs in different order.
JSON structure holds key:value pairs where keys are unique. In most cases order of keys is not important so classes like org.json.JSONObject are storing them in internal HashMap which doesn't preserve insertion order (but allows quick access to values).
When toString() is invoked internally it builds String using that HashMap iterator, so order depends on amount of keys and their hashes, not insertion order.
If you want to preserve order consider using other libraries like gson. Your parsing could look like:
JsonParser jsonParser = new JsonParser();
JsonObject js = jsonParser.parse(decresponse).getAsJsonObject();
and js.toString() would result in
{"userid":123456,"status":"SUCCESS","name":{"firstName":"firstname", ... which seems to be what you ware after.
I am exploring gson and wanted to check if I can remove and add elements. I have the below json
{
"header": {
"timeStamp": "2016-02-09T15:22:36.107-08:00",
"uniqueid": "321ef660",
},
"body": {
"search": {
"searchId": 9206422282,
"DateFrom": "2016-04-15T00:00:00-07:00",
"DateTo": "2016-06-24T00:00:00-07:00"
}
},
"amount": [
{
"amount": 73.704285,
"currency": "USD"
},
"amountagain": {
"amount": 96.791435,
"currency": "USD"
},
"winners": null,
"pgoodId": null,
},
and now I want to add a new element under body like :
{
"header": {
"timeStamp": "2016-02-09T15:22:36.107-08:00",
"uniqueid": "321c5690-1d2e-4403-9c31-029cc47ef660",
},
"body": {
"search": {
"searchId": 9206422282,
"DateFrom": "2016-04-15T00:00:00-07:00",
"DateTo": "2016-06-24T00:00:00-07:00"
"AddANewFieldHere" : **"2016-04-18"**
}
}
when I do
JsonObject jsonObject = new JsonObject();
try {
JsonParser parser = new JsonParser();
JsonElement jsonElement = parser.parse(new FileReader("src/main/resources/search.json"));
jsonObject = jsonElement.getAsJsonObject();
} catch (FileNotFoundException e) {
} catch (IOException ioe){
}
// jsonObject.get("checkin");
jsonObject.addProperty("AddANewFieldHere","2016-04-18");
System.out.print(jsonObject);
}
It adds this property at the end of the document not as I expect under body.
jsonObject is the root node. You need to navigate to the node you want to modify.
JsonObject body = jsonObject.getAsJsonObject("body");
body.addProperty("AddANewFieldHere","2016-04-18");
From the example output, it looks like want it under the path body/search/searchId not body though:
JsonObject searchId = jsonObject
.getAsJsonObject("body")
.getAsJsonObject("search")
.getAsJsonObject("searchId");
searchId.addProperty("AddANewFieldHere","2016-04-18");
