Parsing Facebook Graph API response - java

I'm working on Facebook Scores API for an android app. I query for the user score by accessing the user graph:
https://graph.facebook.com/user_id/scores&access_token={user_access_token}
I get a response like:
{
"data": [
{
"user": {
"name": "Michał Szydłowski",
"id": "100001699654797"
},
"score": 1200,
"application": {
"name": "QuizzlePeople",
"namespace": "quizzlepeople",
"id": "176694722487191"
}
},
{
"user": {
"name": "Michał Szydłowski",
"id": "100001699654797"
},
"score": 1,
"application": {
"name": "Friend Smash!",
"namespace": "friendsmashsample",
"id": "480369938658210"
}
},
{
"user": {
"name": "Michał Szydłowski",
"id": "100001699654797"
},
"score": 0,
"application": {
"name": "Wordox",
"namespace": "wordox-the-game",
"id": "227993680602156"
}
},
{
"user": {
"name": "Michał Szydłowski",
"id": "100001699654797"
},
"score": 0,
"application": {
"name": "SongPop",
"namespace": "songpop",
"id": "323595464361460"
}
}
]
}
How do I extract useful data from this?
I'm trying to take something as a JSONObject, using:
HttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet("https://graph.facebook.com/me?fields=score&access_token=" + token);
HttpResponse resp = client.execute(get);
Log.i("info1", resp.toString());
// Parse the response
HttpEntity responseEntity = resp.getEntity();
String response = EntityUtils.toString(responseEntity);
Log.i("info1", response);
JSONObject result = new JSONObject(response);
JSONArray arr = result.getJSONArray("data");
Log.i("info2", arr.toString());
just to see if I can take anything, say, the array named 'data'. Yet the logcat does not show me anything. It shows the first 2 logs, but not the 3rd. Any ideas?

That looks like JSONObject. You can loop thru it and do whatever you wish with the data.
Have a look at http://json.org/ for documentation for a specific language (I presume you need java so click on the java link).
I appended the data to a table to give you an idea ( jquery / javascript ):

ZOMATO - INVALID API Key error in Eclipse but in POSTMAN response is a success

I am executing a GET request of the ZOMATO API the POSTMAN tool returns a successfull response, however when I try with Eclipse it returns the below message :
403 Error
Invalid API Key
The API key am using in POSTMAN and Eclipse are the same have double checked.
The eclipse code is as stated below:
public class exampleTest {
public static void main(String[] args) {
// TODO Auto-generated method stub
RestAssured.baseURI = "https://developers.zomato.com";
Response res = given().
param("user-key", <api_key>).
when().
get("/api/v2.1/categories").
then().assertThat().statusCode(400).and().contentType(ContentType.JSON).extract().response();
In POSTMAN tool am passing the key in the header rather the URL and response is a success as below:
{
"categories": [
{
"categories": {
"id": 1,
"name": "Delivery"
}
},
{
"categories": {
"id": 2,
"name": "Dine-out"
}
},
{
"categories": {
"id": 3,
"name": "Nightlife"
}
},
{
"categories": {
"id": 4,
"name": "Catching-up"
}
},
{
"categories": {
"id": 5,
"name": "Takeaway"
}
},
{
"categories": {
"id": 6,
"name": "Cafes"
}
},
{
"categories": {
"id": 7,
"name": "Daily Menus"
}
},
{
"categories": {
"id": 8,
"name": "Breakfast"
}
},
{
"categories": {
"id": 9,
"name": "Lunch"
}
},
{
"categories": {
"id": 10,
"name": "Dinner"
}
},
{
"categories": {
"id": 11,
"name": "Pubs & Bars"
}
},
{
"categories": {
"id": 13,
"name": "Pocket Friendly Delivery"
}
},
{
"categories": {
"id": 14,
"name": "Clubs & Lounges"
}
}
]
}
I had this error just try this it will work,
instead of using user-key just use apikey.
developers.zomato.com/api/v2.1/categories?apikey=your API key
Good luck.
You're passing the api key as a query param in RestAssured. It should be passed as a header param. Like this:
.header("user-key", <api_key>)
For me, it worked with by using headers instead of header function call.
RequestSpecification requestSpec=RestAssured.given().headers("Content-Type","application/json","user-key",<api-key>);

Dynamic response of Retrofit

My answer Json depends on whether it succeeds or not.
Unsuccessful example:
{
"success": false,
"errors": {
"email": "Could not find email address"
}
}
Successful example:
{
"success": true,
"user": {
"id": 6,
"fname": "XXXXXX",
"lname": "XXXXXX",
"email": "Username#mail.ca",
"roles": [
"Player"
"Coach"
"manager",
"Admin"
]
"date_registered": "2018-03-16T17: 49: 05.000Z"
}
"Token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzaWQiOiJiNjU1MDVkOGJiYzZhMTg1Y2E5MjU5NDlmNTU0OTc0MTgzM2Y2N2NiNjFjYThkMzNkMTUxY2U2MDhjMTBmNTllIiwiaWF0IjoxNTI3MjY3MzEwLCJleHAiOjE1Mjc4NzIxMTB9.p5pTlNjTsr-8N_8B3M5fW3T6PTTrcFo8D77N0WWgA3c"
}
Now, I want to have a POJO for both at the same time with retrofit.
Thank you
Edit : I just solved the problem by changing the form of JSON to :
{
"success": true,
"data": {
"user": {
"id": 6,
"fname": "XXXXXXX",
"lname": "XXXXXXXX",
"email": "Username#mail.ca",
"roles": [
"player",
"coach",
"manager",
"admin"
],
"activation_state": 0,
"date_registered": "2018-03-16T17:49:05.000Z"
},
"token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzaWQiOiI0MTFlZmI5Y2ExYzY1ZWFlYzQ4Yzg1ZjJkYTQwOThmODBjOTk1NWNjNjcyOTNlODI5NmI4N2RjZWY5OTMzYzljIiwiaWF0IjoxNTI4NDI0MDA1LCJleHAiOjE1Mjg0MjQ2MDl9.lTsQ867Lk78RV2ruaQFyxUNfm58bHpfzEsZnvKJQMXQ"
},
"errors": {}
}
Thank you for help
You could simply return a String Retrofit, and then parse it manually.
If not, then you have to create a POJO object that contains all variables from both objects.
And then at runtime you check if "success" is true/false, and then try to access the underlying varaibles.
Copy your json response and past http://pojo.sodhanalibrary.com/
Then submit
You will get multiple pojo class with respect to your response ,

How to parse a DiagnosticReport from a JSON and print the same JSON again?

I'm parsing a DiagnosticReport from a JSON file and It works fine, but when I try to print the same JSON file throught IParser encode function, the JSON is different to the original. I need to print the same JSON.
Original JSON (String json)
{
"resourceType": "DiagnosticReport",
"text": {
"status": "generated",
"div": "<div><p><b>Narrative A</b></p></div>"
},
"contained": [
{
"resourceType": "Patient",
"id": "1"
},
{
"resourceType": "Observation",
"id": "2",
"meta": {
"lastUpdated": "2017-03-22T22:00:28.089-05:00"
},
"text": {
"div": "<div><p><b>Narrative B</b></p></div>"
},
"comment": "a comment"
}
],
"status": "appended",
"code": {
"coding": [
{
"code": "Report01"
}
]
},
"subject": {
"reference": "#1"
},
"effectiveDateTime": "2017-03-22T22:00:28-05:00",
"issued": "2017-03-22T22:00:28.070-05:00",
"result": [
{
"reference": "#2"
}
]
}
First step is parse and the second step is encode and print
DiagnosticReport report = parser.parseResource(DiagnosticReport.class, json);
String encodeJSON = parser.encodeResourceToString(report);
System.out.println(encodeJSON);
And the result is different because the text tag in the Observation is not showed
{
"resourceType": "DiagnosticReport",
"text": {
"status": "generated",
"div": "<div xmlns=\"http://www.w3.org/1999/xhtml\"><p><b>Narrative A</b></p></div>"
},
"contained": [
{
"resourceType": "Patient",
"id": "1"
},
{
"resourceType": "Observation",
"id": "2",
"meta": {
"lastUpdated": "2017-03-22T22:00:28.089-05:00"
},
"comment": "a comment"
}
],
"status": "appended",
"code": {
"coding": [
{
"code": "Report01"
}
]
},
"subject": {
"reference": "#1"
},
"effectiveDateTime": "2017-03-22T22:00:28-05:00",
"issued": "2017-03-22T22:00:28.070-05:00",
"result": [
{
"reference": "#2"
}
]
}
I'm trying this because I have a DiagnosticReport generated by my software and I need print it completely in a JSON file.
Thanks for your help!!
It's not legal to have narrative in a contained resource, nor is it legal to have meta/lastUpdated. There are invariants that prohibit both. Ideally, the parsing software should have thrown an exception, but it's not overly surprising that the serializer has trouble serializing content that's not supposed to be there.
Look at dom-1 and dom-4 in dstu3 or dstu2

Retrieve value Json field

I know that we have a lot of document on that but in my case I can't apply it.. I have a JSON file like that :
{
"Status": {
"Code": 0,
"Message": "Search OK"
},
"Applications": {
"Application": [{
"Id": 123,
"Name": "Bob"
},
...
]
}
}
I want to retrieve the value of the field "Name".
My code :
String jsonData = readFile("test.json");
JSONObject jobj = new JSONObject(jsonData);
JSONObject jobj2 = (JSONObject) jobj.get("Applications");
JSONArray jarr = new JSONArray(jobj2.getJSONArray("Application").toString());
After that I don't know what to do.. How can I resolve my problem?
Thanks a lot.
For this json:
{
"Status": {
"Code": 0,
"Message": "Search OK"
},
"Applications": {
"Application": [{
"Id": 123,
"Name": "Bob"
}]
}
}
Your code can looks like:
jsonObject
.getJSONObject("Applications")
.getJSONArray("Application")
.getJSONObject(0)
.getString("Name")
