I'm having trouble passing a complex json object in angularjs with $http.post. I'm keep getting a 400 bad request error sent back from the server saying the request was syntactically incorrect. I believe it has something to do with the array since it passes fine when i don't include it.
json i'm passing.
{
customer: {
firstName: "John",
lastName: "Doe",
street: "1234 South Dr",
city: "Detroit",
state: "MI",
zip: "12345",
phone: "123-321-1234",
email: "EMAIL#GMAIL.COM"
},
order: {
orderDate: "06-16-2015",
registerNum: "1",
transactionNum: "7820",
deliveryStatusID: 1,
notes: "Hold order until July",
items: [
{skuID: "1234568",
skuDescription: "Order item 1",
qty: "4",
itemStatusID: 1,
itemStatusDescription: "Backorder"
},
{skuID: "7387491",
skuDescription: "Order item 2",
qty: "1",
itemStatusID: 1,
itemStatusDescription: "Flagged"
}
]
}
}
angular service function
this.addOrder = function(new_order) {
return $http.post(base + "/add", new_order);
};
Spring MVC controller method
#RequestMapping(value="/add", method=RequestMethod.POST)
public void addOrder(#RequestBody CustomerOrder customerOrder) {
System.out.println("----CUSTOMER-INFO----");
System.out.println(customerOrder.getCustomer().getFirstName());
System.out.println(customerOrder.getCustomer().getLastName());
System.out.println("");
System.out.println("----ORDER-INFO----");
System.out.println(customerOrder.getOrder().getOrderID());
System.out.println(customerOrder.getOrder().getOrderDate());
}
The problem only seems to occur when I pass the items array in the json. I've passed the same json object without the items array and it works fine. The format of the json is being sent in the same format that gets returned whenever I GET an order with my angularjs service method so I'm really not sure as to where I'm going wrong with this.
If I need to provide more code please let me know. I appreciate any effort in helping me out.
Thank you.

Well after struggling to find my error in this problem, I finally found a solution. I thought I'd share how I debugged and fix this problem in case someone else is in a similar situation as I was.
After trying every possible way of sending my data in angular to the server and continually getting the same HTTP 400 error, I decided to send the json as a string and accept the json as a string in my spring mvc controller like this.
angular service method:
this.addOrder = function(new_order) {
return $http.post(base + "/add", angular.toJson(new_order));
};
spring controller
#RequestMapping(value="/add", method=RequestMethod.POST, consumes="application/json")
public void addOrder(#RequestBody String json) {
}
From here I simply took the json passed in and used the Jackson ObjectMapper to convert the json string to my POJO like this.
mapping json string to pojo
#RequestMapping(value="/add", method=RequestMethod.POST, consumes="application/json")
public void addOrder(#RequestBody String json) {
ObjectMapper mapper = new ObjectMapper();
try {
CustomerOrder order = mapper.readValue(json, CustomerOrder.class);
System.out.println(order.getCustomer().getFirstName() + " " + order.getCustomer().getLastName());
} catch (JsonGenerationException e) {
e.printStackTrace();
} catch (JsonMappingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
After doing this and running my code, I would get an UnrecognizedPropertyException on a field in my Items class when trying to bind the items json to the List in my Order class. It was just a simple mispelling on the json side and I completely missed it. After correcting this, jackson mapped everything correctly and I no longer get this HTTP 400 Error The request was syntactically incorrect.
Another thing to note is that if you pass your object as a string in angular using the JSON.stringify you may encounter this same exception on hashKey field in the JSON object. The hashKeys are used by angular to monitor changes. I believe you can use a jackson annotation to ignore unknown fields or you can simply use angular.toJson instead which will remove all the hasKey/values for you which is what I did.
Just formatted the Json in a better way. Try this if it helps. Also, post the java classes if possible:
{
"customer": {
"firstName": "John",
"lastName": "Doe",
"street": "1234 South Dr",
"city": "Detroit",
"state": "MI",
"zip": "12345",
"phone": "123-321-1234",
"email": "EMAIL#GMAIL.COM"
},
"order": {
"orderDate": "06-16-2015",

i make a post to an api with rest assured. and than i try to make sure expected data from responsed data ,
but i got some errors like this -> "java.lang.IllegalArgumentException: The parameter "data" was used but not defined. Define parameters using the JsonPath.params(...) function"
my code:
String payload_data = "{" +
"\"Time\":1638057600, " +
"\"exampleType\":example, " +
"\"Id\":[2]}";
RestAssured.defaultParser = Parser.JSON;
given().
contentType(ContentType.JSON).
body(payload_data).
when().
post(api_url).
then().
statusCode(200).
body("data.examples.2.exampleData", equalTo("33"));
}
my json data
{
"success": true,
"data": {
"examples": {
"2": {
"ex_data": 0,
"exampleData": 33,
"data_ex": 0,
}
}
}
First, I tested path "data.examples.2.exampleData" with your json, it works fine. No problem.
You made some mistakes here.
Your payload is invalid json.
{
"Time": 1638057600,
"exampleType": example, //it must be number or String with double quote
"Id": [
2
]
}
You are comparing 2 things with different data types.
"data.examples.2.exampleData" --> int 33
equalTo("33") --> String "33"
Fix: body("data.examples.2.exampleData", equalTo(33));
I am getting the following response from some service call . I am trying to parse the JSON . I am actually new to JAVA and not sure about how to parse JSON objects returned from HTTP call . I am getting the following error :

Well first of all, your json is not valid because of this}:
["list" : /* something here but anyway, not the concern here */ ]
when it should have been
{"list" : /* something here but anyway not the concern here */}
I think your problem is with the understanding of how a JSON file works and what is a json object and a json array. Please correct your JSON input so that we can provide you with insights on how to retrieve the value you need.
Additionally, I would recommend you looking into Jackson lib for parsing JSON objects to JAVA POJOs directly really easily. The link is a great tutorial to get you started here. Furthermore, jackson is already included with Spring so that you literally have nothing to install.
Edit
I misread the JSON input : I saw a : after "list" instead of a ,.
So your JSON is a proper JSON but its a quite uncommon JSON as it is loosely typed and therefore cannot be that easily parsed with standard Jackson library for example. In fact, in the main array, a string is put together with a Json Object which is a very bad practice but that's not your fault as I suppose you are not responsible for the output of this HTTP call.
So how can you actually get your value ? Well let's describe the JSON, you've got here : a JSON array containing a String and another sub JSON array. You want to take some values from the very first JSON object inside the nested json array.
This one :
{
"#type": "com.saba.services.calendar.CalendarElementDetail",
"eventType": "ILTCLASS",
"elementName": "Microservice Application Architecture",
"elementId": "class000000000013497",
"eventId": "timel000000000103609",
"ownerID": "emplo000000000096641",
"locationId": "locat000000000003165",
"locationName": "IND-Bangalore-Karnataka",
"additionalData": {
"#type": "map",
"locationTimeZone": "tzone000000000000042",
"eventID": "class000000000013497",
"locationName": "IND-Bangalore-Karnataka",
"locationId": "locat000000000003165",
"transcriptID": "ofapr000000002962367",
"registrationID": "regdw000000001766254",
"eventName": "Microservice Application Architecture",
"moduleID": "regmd000000002147176",
"courseID": "cours000000000031995"
},
"startDate": {
"#type": "com.saba.customtypes.DateWithLocale",
"date": 1538613000000,
"locale": "03-OCT-2018",
"timeInLocale": "8:30 PM",
"dateInUserTimeZone": "03-OCT-2018",
"timeInUserTimeZone": "5:30 PM",
"dateInCustomTimeZone": null,
"timeInCustomTimeZone": null,
"customTimeZoneDate": 0,
"timeInStandardFormat": "8:30 PM",
"dateInStandardFormat": "10/03/2018"
}
}
The first task here is to gather this object. Let's suppose the nested json array is always in the second position after the string and that the JSON object you want is always at the first position of the nested array which might not be the case depending on your input JSON but this was not precised in your question.
JSONArray mainArray = new JSONArray(resp);
// The nested array is at the second position : 1
JSONArray nestedArray = mainArray.getJSONArray(1);
// the interesting main JSONObject is on the first position
// of the nested array : 0
JSONObject interestingJSONObject = nestedArray.getJSONObject(0);
So now we want "courseId" from "additionnalData" Json Object :
String courseId = interestingJSONObject.getJSONObject("additionalData").getString("courseId");
And there you go!
I faced following problem:
I wanna get list of changes from gerrit repository using this api function https://gerrit-review.googlesource.com/Documentation/rest-api-changes.html#list-changes
When I sent GET request in browser I got response
[
{
"id": "business~develop~I65d58a2345346cb35a0ecbb63d6ed896c7",

"_number": 589,
"owner": {
"_account_id": 1003473
}
}
]
But when I send GET request using RestEasy or other way to send request using Java code:
try {
final ResteasyClient client = new ResteasyClientBuilder().build();
final ResteasyWebTarget target = client
.target("https://gml-jbpm.gomel.iba.by/gerrit/changes/");
String response = target.request().get(String.class);
final JSONArray array = new JSONArray(response);
System.out.println("RestEasy response: " + array);
} catch (final Exception e) {
e.printStackTrace();
}
I get empty response:
[]
How to solve this problem? Why I get empty JSONArray?
I'm a new Java programmer coming from a background in Python. I have weather data that's being collected/returned as a JSON with nested keys in it, and I don't understand how pull the values out in this situation. I'm sure this question has been asked before, but I swear I've Googled a great deal and I can't seem to find an answer. Right now I'm using json-simple, but I tried switching to Jackson and still couldn't figure out how to do this. Since Jackson/Gson seem to be the most used libraries, I'd would love to see an example using one of those libraries. Below is a sample of the data, followed by the code I've written so far.
{
"response": {
"features": {
"history": 1
}
},
"history": {
"date": {
"pretty": "April 13, 2010",
"year": "2010",
"mon": "04",
"mday": "13",
"hour": "12",
"min": "00",
"tzname": "America/Los_Angeles"
},
...
}
}
Main function
public class Tester {
public static void main(String args[]) throws MalformedURLException, IOException, ParseException {
WundergroundAPI wu = new WundergroundAPI("*******60fedd095");
JSONObject json = wu.historical("San_Francisco", "CA", "20100413");
System.out.println(json.toString());
System.out.println();
//This only returns 1 level. Further .get() calls throw an exception
System.out.println(json.get("history"));
}
}
The function 'historical' calls another function that returns a JSONObject
public static JSONObject readJsonFromUrl(URL url) throws MalformedURLException, IOException, ParseException {
InputStream inputStream = url.openStream();
try {
JSONParser parser = new JSONParser();
BufferedReader buffReader = new BufferedReader(new InputStreamReader(inputStream, Charset.forName("UTF-8")));
String jsonText = readAll(buffReader);
JSONObject json = (JSONObject) parser.parse(jsonText);
return json;
} finally {
inputStream.close();
}
}
With Jackson's tree model (JsonNode), you have both "literal" accessor methods ('get'), which returns null for missing value, and "safe" accessors ('path'), which allow you to traverse "missing" nodes. So, for example:
JsonNode root = mapper.readTree(inputSource);
int h = root.path("response").path("history").getValueAsInt();
which would return the value at given path, or, if path is missing, 0 (default value)
But more conveniently, you can just use JSON pointer expression:
int h = root.at("/response/history").getValueAsInt();
There are other ways too, and often it is more convenient to actually model your structure as Plain Old Java Object (POJO).
Your content could fit something like:
public class Wrapper {
public Response response;
}
public class Response {
public Map<String,Integer> features; // or maybe Map<String,Object>
public List<HistoryItem> history;
}
public class HistoryItem {
public MyDate date; // or just Map<String,String>
// ... and so forth
}
and if so, you would traverse resulting objects just like any Java objects.
Use Jsonpath
Integer h = JsonPath.parse(json).read("$.response.repository.history", Integer.class);
Check out Jackson's ObjectMapper. You can create a class to model your JSON then use ObjectMapper's readValue method to 'deserialize' your JSON String into an instance of your model class. And vice-versa.
Try jpath API. It's xpath equivalent for JSON Data. You can read data by providing the jpath which will traverse the JSON data and return the requested value.
This Java class is the implementation as well as it has example codes on how to call the APIs.

I have a trouble to parse this piece of JSON
{
"00408C88A2E6": {

"name": "pippo"},
"00408C91188B": {

},
"00408C944BA0": {
"id": "00408C944BA0",
"name": "topolino"
}
I need to get all the key "id" and "name", I tried with an iterator but I was able to retrive just the first dicts (00408C88A2E6,00408C91188B...), could anyone give me any hint?
Thank you
Edit:
I'm using org.json and to parse this I tried in this way
JSONObject jsonChannels = getHttpJson(url_user_cam);
ArrayList<String> al = new ArrayList<String>();
Log.i(LOG_TAG, jsonChannels.toString());
try{
Iterator<String> iterator = jsonChannels.keys();
while (iterator.hasNext() ){
al.add(iterator.next());
}
}catch(Exception e){
Log.e(LOG_TAG, e.toString());
}
with this piece of code my intent is to get the first dict ("00408C88A2E6") after make it I need to access to "id" and "name" element, hwo can i do it?
As pointed in the comments, it looks like your JSON is incomplete. Maybe a pasting error ?
Do you do it manually or do you use a library ?
Have you tried using the "official" Java JSON package ?
