unable to parse a valid JSON String - java

I am trying to parse a JSON String and map it to a hashmap, I have a valid JSONString from server but when I traverse through it, all I can get it is the first result.
JSONArray peoples = null;
ArrayList<HashMap<String, String>> personList = new ArrayList<HashMap<String,String>>();
JSONObject jsonObj = new JSONObject(value);
Log.d("Jello",jsonObj.toString());
peoples = jsonObj.getJSONArray("product");//check here
Log.d("Jello",peoples.toString());
for(int i=0;i<peoples.length();i++){
JSONObject c = peoples.getJSONObject(i);
String service_group = c.getString("sgroup");
String service = c.getString("service");
String value = c.getString("value");
String updated_at = c.getString("updated_at");
HashMap<String,String> persons = new HashMap<String,String>();
persons.put("service_group",service_group);
persons.put("service",service);
persons.put("value",value);
persons.put("updated_at",updated_at);
personList.add(persons);
}
My JSON String is :
{"product":[{"sgroup":"Dummy_BIG_ONE","service":"Dummy_UNDER_BIG_ONE","code":"128","value":"0","updated_at":"2015-12-04 21:21:00"}]}{"product":[{"sgroup":"Hello Monkey","service":"Do u work","code":"123","value":"0","updated_at":"2015-12-04 21:27:51"}]}{"product":[{"sgroup":"Checking from Android Device","service":"Monkey","code":"12345","value":"0","updated_at":"2015-12-04 22:55:39"}]}{"product":[{"sgroup":"Checking from Android Device","service":"Monkey","code":"12345","value":"0","updated_at":"2015-12-04 22:55:40"}]}{"product":[{"sgroup":"Checking from Android Device","service":"Monkey","code":"12345","value":"0","updated_at":"2015-12-04 22:55:42"}]}{"product":[{"sgroup":"Hello World","service":"Donkey","code":"24411","value":"0","updated_at":"2015-12-04 22:57:05"}]}{"product":[{"sgroup":"lkfnhjdiofho","service":"dfjdifj","code":"1101","value":"0","updated_at":"2015-12-05 01:15:49"}]}{"product":[{"sgroup":"Baal","service":"Saal","code":"1234","value":"21","updated_at":"2015-12-05 01:34:59"}]}{"product":[{"sgroup":"Inis","service":"Mona","code":"1234","value":"1001","updated_at":"2015-12-05 01:39:51"}]}{"product":[{"sgroup":"Medical Treatment Loan","service":"Number of referral slip","code":"128","value":"0","updated_at":"2015-12-05 01:50:42"}]}{"product":[{"sgroup":"Medical Treatment Loan","service":"Number of referral slip","code":"128","value":"0","updated_at":"2015-12-05 01:55:12"}]}{"product":[{"sgroup":"Medical Treatment Loan","service":"Number of referral slip","code":"128","value":"1000","updated_at":"2015-12-05 01:56:10"}]}
or HERE
here is how I am sending the JSON
while($row = mysql_fetch_assoc($output))
{
$product = array();
$product["sgroup"] = $row["service_group"];
$product["service"] = $row["service"];
$product["code"] = $row["code"];
$product["value"] = $row["amount"];
$product["updated_at"] = $row["updated_at"];
// user node
$response["product"] = array();
array_push($response["product"], $product);
// echoing JSON response
echo json_encode($response);
}
I want to add all the data's from the JSON in my ArrayList so that I can use it later.
Thank you for your help.

First, there are online tools available to determine if your JSON is valid.
Here is a general example of a better way to format your JSON data:
<?php
$bigArray = array();
for ($x = 0; $x <= 10; $x++) {
$product = array();
$product["sgroup"] = $x;
$product["service"] = $x;
$product["code"] = $x;
$product["value"] = $x;
$product["updated_at"] = $x;
array_push($bigArray, $product);
}
// echoing JSON response
echo json_encode($bigArray);
?>
Which gives this valid JSON response that is simple and easy to parse:
[
{
"sgroup":0,
"service":0,
"code":0,
"value":0,
"updated_at":0
},
{
"sgroup":1,
"service":1,
"code":1,
"value":1,
"updated_at":1
},
{
"sgroup":2,
"service":2,
"code":2,
"value":2,
"updated_at":2
},
{
"sgroup":3,
"service":3,
"code":3,
"value":3,
"updated_at":3
},
{
"sgroup":4,
"service":4,
"code":4,
"value":4,
"updated_at":4
},
{
"sgroup":5,
"service":5,
"code":5,
"value":5,
"updated_at":5
},
{
"sgroup":6,
"service":6,
"code":6,
"value":6,
"updated_at":6
},
{
"sgroup":7,
"service":7,
"code":7,
"value":7,
"updated_at":7
},
{
"sgroup":8,
"service":8,
"code":8,
"value":8,
"updated_at":8
},
{
"sgroup":9,
"service":9,
"code":9,
"value":9,
"updated_at":9
},
{
"sgroup":10,
"service":10,
"code":10,
"value":10,
"updated_at":10
}
]
As for the parsing, using a HashMap is not the best way. Create a list of Person POJO objects.
First define the Person class:
class Person {
public String group;
public String service;
public String value;
public String updated;
public Person(String g, String s, String v, String u) {
group = g;
service = s;
value = v;
updated = u;
}
}
Then, parsing is fairly simple:
List<Person> personList = new ArrayList<>();
JSONArray jsonArr;
try {
jsonArr = new JSONArray(response);
for(int i=0;i<jsonArr.length();i++){
JSONObject c = jsonArr.getJSONObject(i);
String service_group = c.getString("sgroup");
String service = c.getString("service");
String value = c.getString("value");
String updated_at = c.getString("updated_at");
Person p = new Person(service_group, service, value, updated_at);
personList.add(p);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

You should put your products into json array:
[
{
"product": {
"sgroup": "lkfnhjdiofho",
"service": "dfjdifj",
"code": "1101",
"value": "0",
"updated_at": "2015-12-05 01:15:49"
}
},
{
"product": {
"sgroup": "Baal",
"service": "Saal",
"code": "1234",
"value": "21",
"updated_at": "2015-12-05 01:34:59"
}
},
{
"product": {
"sgroup": "Inis",
"service": "Mona",
"code": "1234",
"value": "1001",
"updated_at": "2015-12-05 01:39:51"
}
},
{
"product": {
"sgroup": "Medical Treatment Loan",
"service": "Number of referral slip",
"code": "128",
"value": "0",
"updated_at": "2015-12-05 01:50:42"
}
},
{
"product": {
"sgroup": "Medical Treatment Loan",
"service": "Number of referral slip",
"code": "128",
"value": "0",
"updated_at": "2015-12-05 01:55:12"
}
},
{
"product": {
"sgroup": "Medical Treatment Loan",
"service": "Number of referral slip",
"code": "128",
"value": "1000",
"updated_at": "2015-12-05 01:56:10"
}
}
]
And you have to change your parser little bit:
JSONArray jsonArray = new JSONArray(string);
for(int i=0;i<jsonArray.length();i++){
JSONObject c = jsonArray.getJSONObject(i).getJSONObject("product");
String service_group = c.getString("sgroup");
String service = c.getString("service");
String value = c.getString("value");
String updated_at = c.getString("updated_at");
HashMap<String,String> persons = new HashMap<String,String>();
persons.put("service_group",service_group);
persons.put("service",service);
persons.put("value",value);
persons.put("updated_at",updated_at);
personList.add(persons);
}
You don't need put your object into "product" attribute, but directly into array :
[
{
"sgroup": "lkfnhjdiofho",
"service": "dfjdifj",
"code": "1101",
"value": "0",
"updated_at": "2015-12-05 01:15:49"
},
{
"sgroup": "Baal",
"service": "Saal",
"code": "1234",
"value": "21",
"updated_at": "2015-12-05 01:34:59"
},

how to escape part of json loaded as object

I'm not fluent in API testing hence my question. I have a body to POST (mock) that will consist of:
{
"request":
{
"urlPath": "path/to/",
"method": "POST",
"bodyPatterns":[{
"equalToJson" : "{\n\"query\": [\n{\n\"name\": \"name1\",\n\"value\": \"123\"\n },\n{\n\"name\": \"name2\",\n\"value\": \"345\"\n},\n{\n\"name\": \"name3\",\n\"value\": \"someName\"\n}\n],\n\"anotherItem\": [],\n\"side\": 77,\n\"pageSize\": 44\n}", "jsonCompareMode": "LENIENT"
}]
},
"response":
{
"status": 200,
"headers":
{
"Content-Type" : "application/json"
},
"body": "{"items\": [\n{\n\"item\": 1,\n
\"item2\": 2,\n
etc
"\n}\n]\n}"
}
}
I want to use some pojo classes to separately create Request and Response:
public Request initRequest() {
BodyPattern bodyPat = new BodyPattern();
Query query = new Query();
Query query2 = new Query();
Query query3 = new Query();
EqualToJson equalToJ = new EqualToJson();
query.setName("name1");
query.setValue("123");
query2.setName("name2");
query2.setValue("345");
query3.setName("name2");
query3.setValue("someName");
List<Query> queryList = new ArrayList<>();
queryList.add(query);
queryList.add(query2);
queryList.add(query3);
equalToJ.setQuery(queryList);
List<Filter> filtersList = new ArrayList<>();
equalToJ.setFilter(filtersList);
equalToJ.setSide(77);
equalToJ.setPageSize(44);
List<EqualToJson> eqList = new ArrayList<>();
eqList.add(equalToJ);
req.setUrlPath(URL + "/Test001");
req.setMethod("POST");
bodyPat.setEqualToJson(eqList);
bodyPat.setJsonCompareMode("LENIENT");
List<BodyPattern> bodyPatList = new ArrayList<>();
bodyPatList.add(bodyPat);
req.setBodyPatterns(bodyPatList);
return req;
}
To see it in more user-friendly view, here you go:
{
"request": {
"urlPath": "/path/to",
"method": "POST",
"bodyPatterns": [
{
"equalToJson": {
"query": [
{
"name": "name1",
"value": "123"
},
{
"name": "name2",
"value": "345"
},
{
"name": "name3",
"value": "someName"
}
],
"filter": [
],
"side": 77,
"pageSize": 44
},
"jsonCompareMode": "LENIENT"
}
]
},
"response": {
"status": 200,
"headers": {
"Content-Type": "application/json"
},
"body": {
"side": 77,
"pageSize": 44,
"items": [
{
"name1": "123",
"name2": "345",
"name3": "someName"
etc...
}
]
}
}
}
Similarly, I do with Response.
My question is, how can I make to have just a part of this json (BodyPatters) as escaped signs? Mock is created this way that it only accepts escaped characters in this part of json.
I can of course hardcode this payload, but I want to have control over those fields' values and steer them, as parameters.
I really have no idea how to handle this.
You can use objectmapper of jackson to convert Object to String. For example:
void name2() throws JsonProcessingException {
ObjectMapper mapper = new ObjectMapper();
Query query = new Query("name1", "123");
EqualToJson equalToJson = new EqualToJson();
equalToJson.setQuery(Arrays.asList(query));
BodyPattern bodyPattern = new BodyPattern();
bodyPattern.setEqualToJson(mapper.writeValueAsString(equalToJson));
String bodyPatternText = mapper.writerWithDefaultPrettyPrinter()
.writeValueAsString(bodyPattern);
System.out.println(bodyPatternText);
}
#Data
#AllArgsConstructor
static class Query{
private String name;
private String value;
}
#Data
static class EqualToJson {
private List<Query> query;
}
#Data
static class BodyPattern {
private String equalToJson;
}
This is a result:
{
"equalToJson" : "{\"query\":[{\"name\":\"name1\",\"value\":\"123\"}]}"
}

Add hashmap having possible serialized JSON values to a JSON string as a node

What is the cheapest way to take the jsonstring and hashmap below and produce the result in JAVA?
pseudocode data example:
String jsonstring = {
"people": {
"name": "name1",
},
"addresses": {
"address1": {
"number": "1234",
"city": "europa"
}
}
}
HashMap hashmap = {
["string.a.1"] = "stringa1",
["string.a.2"] = "stringa2",
["object.a.1"] = "{/"item1/":/"value1/"}" // serialized JSON object
}
String result = {
"people": {
"name": "name1",
},
"addresses": {
"address1": {
"number": "1234",
"city": "europa"
}
},
"buffer": {
"string.a.1": "stringa1",
"string.a.2": "stringa2",
"object.a.1": {
"item1": "value1"
}
}
}
Thanks in advance for any help.

Can someone help me pls?
First be sure you have retrieved JSON String,
Then You can easily access the properties inside them like
try {
JSONArray jsonArray = new JSONArray(json);
JSONObject obj = jsonArray.getJSONObject(0); //0 for just retrieving first object you can loop it
String myVehicleID = obj.getString("vehicleId"); //To retrieve vehicleId
//Similarly do it for others as well
} catch (JSONException e) {
e.printStackTrace();
}

Add a Key value to Json String generated from GSON.toJSON

String jsonResponse=Utils.getGsonInstance().toJson(Object);
jsonResponse returns :
[
{
"Key":"1",
"Code": "11",
},
{
"key":"2",
"code": "22",
}
]
End result I am looking for is to wrap this JSON-String in another Key E.g.
{
"MainObj":
[
{
"Key":"1",
"Code": "11",
},
{
"key":"2",
"code": "22",
}
]
}
Is there a way I can achieve this using GSON Api ?
I tried ::
JSONObject jsonObject = new JSONObject();
jsonObject.put("MainObj",jsonResponse);
Output I am getting is :
{"MainObj": "[{\"Key\":\"1",\"Code\":\"11\"}, {\"Key\":\"2",\"Code\":\"22\"}]"}
Continue with GSON like :
public class MainObj {
#SerializedName("MainObj")
public List<Key> Main;
public class Key {
#SerializedName("Key")
public String Key;
#SerializedName("code")
public String Code;
}
}
And change
JSONObject jsonObject = new JSONObject();
jsonObject.put("MainObj",jsonResponse);
by
String tmp = new Gson().toJson(new MainObj());

how to parse this in android with json

I want to parse this json in android. Can you help me how to parse, if i need to start from head to parse or from results for this I don't know. Can you help me
{
"head":
{
"link": [],
"vars": ["city", "country"]
},
"results":
{
"distinct": false,
"ordered": true,
"bindings":
[
{
"city":
{
"type": "uri",
"value": "http://dbpedia.org/resource/Ferizaj"
} ,
"country":
{
"type": "uri",
"value": "http://dbpedia.org/resource/Kosovo"
}
}
]
}
}
Okay, first of all the JSON string you've given is invalid. I've written my answer based on the correct version of the JSON string that you have provided
{
"head":
{
"link": [],
"vars": ["city", "country"]
},
"results":
{
"distinct": false,
"ordered": true,
"bindings":
[
{
"city":
{
"type": "uri",
"value": "http://dbpedia.org/resource/Ferizaj"
} ,
"country":
{
"type": "uri",
"value": "http://dbpedia.org/resource/Kosovo"
}
}
]
}
}
Now, to get the "values", you'll need to do this.
JSONObject jsonObject = new JSONObject(response);
JSONObject results = jsonObject.getJSONObject("results");
JSONArray bindings = results.getJSONArray("bindings");
for (int i = 0; i < bindings.length(); i++) {
JSONObject binding = bindings.getJSONObject(i);
JSONObject city = binding.getJSONObject("city");
// Get value in city
String cityValue = city.getString("value");
Log.d("CITY", cityValue);
JSONObject country = binding.getJSONObject("country");
// Get value in country
String countryValue = country.getString("value");
Log.d("COUNTRY", countryValue);
}
