Convert a string from web service to JSON array

I want to convert this web service string to JSONArray , but it seems to have a problem , although I've validated it.
[
{
"hireDate": null,
"homePhoneNumber": null,
"gender": null,
"city": null,
"mobileNumber": null,
"idNumber": 123,
"religion": null,
"leftOver": 1,
"annualVacations": 5,
"dob": null,
"name": null,
"rank": 0,
"id": 1,
"workingHours": [],
"email": "ayman.daraghmah#exalt.ps",
"managers": [],
"alternativeMobileNumber": null,
"activated": true,
"username": "ayman.daraghmah#exalt.ps"
},
{
"hireDate": null,
"homePhoneNumber": null,
"gender": null,
"city": null,
"mobileNumber": null,
"idNumber": 123,
"religion": null,
"leftOver": 1,
"annualVacations": 5,
"dob": null,
"name": null,
"rank": 0,
"id": 11,
"workingHours": [],
"email": "aymandaraghmah#gmail.com",
"managers": [],
"alternativeMobileNumber": null,
"activated": true,
"username": "aymandaraghmah#gmail.com"
}
]
My Code:
JSONArray js = new JSONArray(payload);
what should the format of payload be to create the JSONArray ?

Looking at the code it looks like it should work. Following sample worked for me (The JSON is taken as a string for testing).
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class Main {
public static void main(String[] args) throws JSONException {
String test = "[{\"hireDate\": null,\"homePhoneNumber\": null,\"gender\": null,\"city\": null,\"mobileNumber\": null,\"idNumber\": 123,\"religion\": null,\"leftOver\": 1,\"annualVacations\": 5,\"dob\": null,\"name\": null,\"rank\": 0,\"id\": 1,\"workingHours\": [],\"email\": \"ayman.daraghmah#exalt.ps\",\"managers\": [],\"alternativeMobileNumber\": null,\"activated\": true,\"username\": \"ayman.daraghmah#exalt.ps\"},{\"hireDate\": null,\"homePhoneNumber\": null,\"gender\": null,\"city\": null,\"mobileNumber\": null,\"idNumber\": 123,\"religion\": null,\"leftOver\": 1,\"annualVacations\": 5,\"dob\": null,\"name\": null,\"rank\": 0,\"id\": 11,\"workingHours\": [],\"email\": \"aymandaraghmah#gmail.com\",\"managers\": [],\"alternativeMobileNumber\": null,\"activated\": true,\"username\": \"aymandaraghmah#gmail.com\"}]";
JSONArray jsonArray = new JSONArray(test);
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject explrObject = jsonArray.getJSONObject(i);
System.out.println(explrObject.getString("username"));
}
}
}

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();
}

unable to parse a valid JSON String

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 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);
}

There is no element called summary, you may try

}
if that doesn't work, please post your stacktrace, (logcat)

You don't have any tag named "originID". but you are trying to get String from it.
Similarly,you don't have tag "summary" also but you are trying to get JSONObject from it.
