I have a JSON response that looks like the following:
[
{
"id": 5,
"user_id": 1,
"message": "Hello",
"children": [
{
"id": 7,
"user_id": 2,
"message": "Hi",
"children": [
{
"id": 8,
"user_id": 3,
"message": "Hey",
"children": [
]
}
]
}
]
},
{
"id": 6,
"user_id": 4,
"message": "Ahoy",
"children": [
]
}
]
I already have the model created (Message.java). The children can be retrieved by calling getChildren(). The response is saved in a list List<Message> messages.
How can I loop through this JSON array to get the contents of each child until there is no child left? Is this possible without a recursive function?
I Assume you have List messages :
Here is how you can browse through all children with both recursion and iterative way :
List<Message> messages = //you already have that
System.out.println("Using Recusion : ");
for (Message message : messages) {
printMessage(message);
}
System.out.println("Using Iterative : ");
Stack<Message> stack = new Stack<>();
stack.addAll(messages);
while (!stack.empty()) {
Message item = stack.pop();
System.out.println(item.getId() + ":" + item.getUser_id() + ":" + item.getMessage());
for (Message chidren : item.getChildren()) {
stack.push(chidren);
}
}
and here is the printMessage method :
public static void printMessage(Message pmessage) {
System.out.println(pmessage.getId() + ":" + pmessage.getUser_id() + ":" + pmessage.getMessage());
for (Message message : pmessage.getChildren()) {
printMessage(message);
}
}
public void printJsonObject(JSONObject jsonObj) {
for (String keyStr : jsonObj.keySet()) {
Object keyvalue = jsonObj.get(keyStr);
//Print key and value
System.out.println("key: "+ keyStr + " value: " + keyvalue);
//for nested objects iteration if required
if (keyvalue instanceof JSONObject)
printJsonObject((JSONObject)keyvalue);
}
}

I have fetched some integer values from getAPI:
List<String> jsonResponse = response.jsonPath().getList("$");
for (int i = 0; i < jsonResponse.size(); i++) {
if (getJsonPath(response, "type[" + i + "]").equals("agent_sms_missed_call")) {
agentMissedCallId = getJsonPath(response, "id[" + i + "]");
break;
}
}
for (int i = 0; i < jsonResponse.size(); i++) {
if (getJsonPath(response, "type[" + i + "]").equals("caller_sms_missed_call")) {
callerMissedCallSmsId = getJsonPath(response, "id[" + i + "]");
break;
}
}
Now I want to send the value of agentMissedCallId and callerMissedCallSmsId in PUT API : How can i acheive that .
{
"sms_template": [
idFetched(agentMissedCallId), idFetched(callerMissedCallSmsId)
]
}
Response I am getting from a GET API :
[
{
"id": 29169,
"name": "Template 1",
"type": "agent_sms_missed_call"
},
{
"id": 29170,
"name": "Template 2",
"type": "caller_sms_missed_call"
}
]
Request body I want :
{
"sms_template": [
29169
],
"name": "Hello ",
"destination": "hangup||1",
"description": "number for department"
}
This below approach is not recommended, but it doesn't require any 3rd lib, so I think it works for you.
Map<String, Object> body = new LinkedHashMap<>();
body.put("sms_template", List.of(agentMissedCallId, callerMissedCallSmsId));
body.put("name", "Hello ");
body.put("destination", "hangup||1");
body.put("description", "number for department");
given().log().body().contentType(ContentType.JSON)
.body(body)
.post("https://postman-echo.com/post");
How to keep other fields in the Jolt transform JSON array, I am trying to use wildcard but fields are not added in the final output?
Here is the example input I am using
[
{
"foundduring": "D-DC",
"user_type": "type1",
"location": "location1"
},
{
"foundduring": "D-DG",
"user_type": "type2",
"location": "location2"
},
{
"foundduring": "D-DI",
"user_type": "type3",
"location": "location3"
}
]
I am using the following Jolt transformation and also trying wildcard:
[
{
"operation": "shift",
"spec": {
"*": {
"foundduring": {
"D-DC": {
"#CycleCount": "[&3].foundduring"
},
"D-DG": {
"#Pick": "[&3].foundduring"
},
"D-DI": {
"#Issue": "[&3].foundduring"
}
},
"#": "&"
}
}
}
]
Following is my expected output where shift operation happened and then need to keep all other fields as it it
[
{
"foundduring" : "CycleCount",
"user_type" : "type1",
"location" : "location1"
},
{
"foundduring" : "Pick",
"user_type" : "type2",
"location" : "location2"
},
{
"foundduring" : "Issue",
"user_type" : "type3",
"location" : "location3"
}
]
Actual Output coming:
[
{
"foundduring": "CycleCount"
},
{
"foundduring": "Pick"
},
{
"foundduring": "Issue"
}
]
Consider using "*" wildcard as else case instead of "#" such as
[
{
"operation": "shift",
"spec": {
"*": {
"foundduring": {
"D-DC": {
"#CycleCount": "[&3].&2"
},
"D-DG": {
"#Pick": "[&3].&2"
},
"D-DI": {
"#Issue": "[&3].&2"
}
},
"*": "[&1].&"
}
}
}
]
Btw, no need to get the key name "foundduring", just use &2 substitution to go 2 level up from the current branch and grab that value.

So I am incredibly new to Java and am needing help parsing a JSON response. I already have the method in which I am using to do so, but need help figuring out what exactly I am doing wrong.
I am using an API to retrieve recipes from a site. I am trying to get a list of recipes ("hits" in this case I assume?) that I can then show to the user.
Obviously I need the recipe name ("label" in this case) and other information. Can anyone help me?
Here is the response api response I am getting:

This is currently the method I am using to parse the JSON object:
public void onResponse(Call call, Response response) throws IOException {
if (response.isSuccessful()) {
final String myResponse = response.body().string();
getActivity().runOnUiThread(new Runnable() {
private Object Date;
#Override
public void run() {
String jsonData = myResponse;
query_result.setText(myResponse);
Log.d("response5", myResponse);
//JSONObject jsonData1 = new JSONObject(myResponse);
JSONObject Jobject = null;
try {
Jobject = new JSONObject(jsonData);
Log.d("jobject", Jobject.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JSONArray Jarray = null;
try {
Jarray = Jobject.getJSONArray("hits");
} catch (JSONException e) {
e.printStackTrace();
}
for (int i = 0; i < Jarray.length(); i++) {
JSONObject object;
try {
object = Jarray.getJSONObject(i);
try {
JSONArray Recipe = object.getJSONArray("recipe");
}catch (JSONException e){
e.printStackTrace();
}
for (int j = 0; j < Jarray.length(); j++){
JSONObject object2 = null;
try {
object2 = Jarray.getJSONObject(j);
String Name = object2.getString("label");
String Photo = object2.getString("image");
Log.d("rec_query", " " + Photo);
}catch (JSONException e){
e.printStackTrace();
Log.d("response6:", e.toString());
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
});
}
}
});
return null;
}
}
NOTE THE {} {} are just different recipes...it wouldnt fit the whole response
At the moment, when I try to print my variables in the Log, I am getting a message that says the variable is empty (the variable that i used to store the different recipes/"hits".
Your response seems incomplete, it's not in the correct JSON format，Provide the right format and I'll try to help you
String s = "{\n" +
" \"a1\":\"1\",\n" +
" \"b2\":[\n" +
" {\n" +
" \"b21\":\"vb21\"\n" +
" },\n" +
" {\n" +
" \"b22\":\"vb22\"\n" +
" }\n" +
" ]\n" +
"}";
JSONObject object = JSON.parseObject(s);
String vb21 = object.getJSONArray("b2").getJSONObject(0).getString("b21");
like this,and neep to import com.alibaba.fastjson
But i dont`t know if you can use fastjson
Im trying to restructure duplicate json values in my JSON Structure and rearrange them using the simplest possible method.
I got to the point where I managed to get it stored in a map each time it loops over the JSONObject but from here how do I proceed to store the mapping to achieve my desired outcome? Thank you so much in advance.

I have a big problem with XMLSerializer... I use JSON lib (net.sf.json) and this is my code:

" <oldDocument>\n" +
" <oldAppId>true</oldAppId>\n" +
" <name>App</name>\n" +

"</state>";
String result = null;
XMLSerializer xmlSerializer = new XMLSerializer();
xmlSerializer.setForceTopLevelObject(true);
result = XMLSerializer.class.toGenericString();
System.out.println(result);
}
My current output is:
"state": {

}
],
"oldDocument": {
"oldAppId": "true",

But I would like have this msg:
{
"state": {
"appId": "newID",
"newDocuments": {
"nameValues": [
{
"name": "test1",
"value": "123456"

"value": "987654"
}
]
},
"oldDocument": {
"oldAppId": "true",
"name": "App",
"source": "NA"
}
}}
Unfortunately now I missing tag nameValues. Could someone help me with this?
