How to remove escaping slashes from a json inside another json? - json

I have the following json, that is being populated by:
new Gson().toJson(batch.getProducts());
But when im adding it to my main JSONObject, the fact that it's a value of a json is doing all the json (even the keys) be escaped.
{"name":"Ufud","store":2,"products":"[{\"name\":\"Test2\",\"stock\":2,\"value\":19.9},{\"name\":\"Test2\",\"stock\":2,\"value\":19.9},{\"name\":\"Teste2\",\"stock\":2,\"value\":19.9}]"}
Is there any method to prevent this?


If you're going to manipulate your json in future you may consider converting it not into a string, but into a JsonElement which can be quite easily added to already existing JsonObject
JsonObject mainObject = getMainObject(); //method which creates your main object. You can change it to variable reference
JsonElement productsElement = new Gson().toJsonTree(batch.getProducts()); //converting your object into JsonElement
mainObject.add("products", productsElement); //insering products element into object.
String json = new Gson().toJson(mainObject); //converting object with products element into a json string

How to convert Object to Jooq JSON

I have a String (jsonData) being mapped to json via Jackson Object mapper as below to JaxB.
var completeJson = objectMapper.readValue(jsonData, Data.class);
myDto.setFirstName(completeJson.getFirstName())
myDto.setLastName(completeJson.getLastName()))
.....
.....etc..etc
I'm able to map to the above strings just fine. However, I'm having problems mapping
to a jooq JSON object. I guess I will now have to convert jsonData to jooq JSON.
How would I do this?
JSON newJson = objectMapper.(best method to use);
myDto.setJsonSource(newJson)
Or maybe I have to create some sort of wrapper?
DTO configured by jooq
public myDto setJsonSource(JSON jsonSource) {
this.jsonSource = jsonSource;
return this;
}

The org.jooq.JSON type is just a wrapper around a string, so why not just use:
JSON json = JSON.json(objectMapper.writeValueAsString(object));

want to bind string using comma separated using for loop

string json="[{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/bdc2cd8e1da3451c84e332d1aa74f605\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"IT mobile computing,Comm Skills\",\"Name\":\"JAVA\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"bdc2cd8e1da3451c84e332d1aa74f605\",\"CreatedON\":\"2015_09_08-11:19:50\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\" },{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/3aae020c256f4dc1ab705af67bede2c7\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"IT mobile computing,Comm Skills\",\"Name\":\"Spring\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"3aae020c256f4dc1ab705af67bede2c7\",\"CreatedON\":\"2015_09_04-16:58:05\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\"},{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/c139b33a22a94a25bf624b94450aee3e\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"Social Skills\",\"Name\":\"SQL\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"c139b33a22a94a25bf624b94450aee3e\",\"CreatedON\":\"2015_09_04-16:54:44\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\"}]";
This is my JSON string and I want to only "Name" field with comma separated into another variable.
For example, example:
string res={"JAVA","SPRING","SQL"}

What language are you trying to do this in? My first guess is javascript but i wasnt sure.
If its JavaScript, then you can get starten by turning the json string into a JavaScript object like this:
var jsonElements = JSON.parse (json);
From there its just looping and collecting the name property from each object.
Now we'll do this from C# instead
Ok, since you are doing the parsing from C# you would want this code instead:
string json = "[{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/bdc2cd8e1da3451c84e332d1aa74f605\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"IT mobile computing,Comm Skills\",\"Name\":\"JAVA\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"bdc2cd8e1da3451c84e332d1aa74f605\",\"CreatedON\":\"2015_09_08-11:19:50\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\" },{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/3aae020c256f4dc1ab705af67bede2c7\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"IT mobile computing,Comm Skills\",\"Name\":\"Spring\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"3aae020c256f4dc1ab705af67bede2c7\",\"CreatedON\":\"2015_09_04-16:58:05\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\"},{\"ParentId\":\"a9764da3147845c184bd272cef6a5937\",\"Path\":\"/LMS/Cabinet/c139b33a22a94a25bf624b94450aee3e\",\"CreatedBY\":\"admin\",\"IsActive\":\"Y\",\"CabinetName\":\"LMS\",\"FolderTag\":\"Social Skills\",\"Name\":\"SQL\",\"UpdatedBY\":\"\",\"Type\":\"Folder\",\"IsDelete\":\"N\",\"UpdatedON\":\"\",\"Id\":\"c139b33a22a94a25bf624b94450aee3e\",\"CreatedON\":\"2015_09_04-16:54:44\",\"TemplateId\":\"dd42c8a71a954c1d948ef35492ee1242\"}]";
dynamic jsonObj = (JArray)JsonConvert.DeserializeObject(json);
List<string> names = new List<string>();
foreach (JObject item in jsonObj)
{
names.Add(item["Name"].ToString());
}
Deserialize the string and cast it to a JArray. Then foreach element in the array, we look at the Name property of the element. I tested this code in visual studio and it appears to work.

RestSharp: get JSON string after deserialization?

using RestSharp is there a way to get the raw json string after it has been deserialized into an object? I need that for debugging purposes.
I'd like to see both the deserialized object and the originally received json string of that object. It's part of a much bigger json string, an item in an array and I only need that specific item json code that's got deserialized into the object.

To help you out this should work, this is a direct example of some of my work, so your's might be a bit different.
private void restClient()
{
string url = "http://apiurl.co.uk/json";
var restClient = new RestClient(url);
var request = new RestRequest(Method.GET);
request.AddParameter("apikey", "xxxxxxxxxx");
restClient.ExecuteAsync<Entry>(request, response =>
{
lstboxtop.Items.Add(response.Content);
});
}
The line lstboxtop is a listbox and using the response.content will literally print the whole api onto your app, if you call it first that would be what you are looking for

difference between json string and parsed json string

what is the difference between json string and parsed json string?
for eg in javascript suppose i have a string in the json format say [{},{}]
parsing this string will also produce the same thing.
So why do we need to parse?

It's just serialization/deserialization.
In Javscript code you normally work with the object, as that lets you easily get its properties, etc, while a JSON string doesn't do you much good.
var jsonobj = { "arr": [ 5, 2 ], "str": "foo" };
console.log(jsonobj.arr[1] + jsonobj.str);
// 2foo
var jsonstr = JSON.stringify(jsonobj);
// cannot do much with this
To send it to the server via an Ajax call, though, you need to serialize (stringify) it first. Likewise, you need to deserialize (parse) from a string into an object when receiving JSON back from the server.

Great question. The difference is transfer format.
JSON is only the 'Notation' of a JavaScript Object, it is not actually the JavaScript 'object-literal' itself. So as the data is received in JSON, it is just a string to be interpreted, evaluated, parsed, in order to become an actual JavaScript 'Object-Literal.
There is one physical difference between the two, and that is quotation marks. It makes sense, that JSON needs to be a string to be transferred. Here is how:
//A JavaScript Object-Literal
var anObj = { member: 'value'}
//A JSON representation of that object
var aJSON = { "member":"value" }
Hope that helps. All the best! Nash

I think a parsed json string should be the string data into the actual javascript objects and data arrays (or whichever language the json string contains)

The JSON object contains methods for parsing JSON and converting values to JSON.
It can't be called or constructed, and aside from its two method properties it has no interesting functionality of its own.
JSONParser parser = new JSONParser();
Object object = parser.parse(Message.toString());
JSONObject arObj = (JSONObject) object;

deserializing json with arrays

im using jackson to deserialize some Json. I am reading through a large json document and pulling out blocks and telling jackson to take that block and deserialize it to an object that I created (Actually several objects as there are nested arrays) in java to match the json.
The code im using to deserialize is
fooObject newFoo = mapper.readValue(newNode,fooObject.class);
The problem is there is a value in the block that is sometimes a hash such as
addWidgetStrategy={"get":2,"spend":6,"textLabel":"bikes"}
and sometimes an array
addWidgetStrategy=[{"get":1.5,"spend":3,"textLabel":"thursday"},{"get":3,"spend":5,"textLabel":"tuesday"}]
So in fooObject I need to deal with addWidgetStrategy which has its own object. If in fooObject I put
public addWidgetStrategy addWidgetStrategy;
The above works until it tried to deserialize an array
If I put
public List<addWidgetStrategy> addWidgetStrategy;
it works just for arrays and blows up when its just a single hash
How can I parse that same Json element addWidgetStrategy regardless if its an array or a single hash?

For arrays it should be:
fooObject[] newFoo = mapper.readValue(newNode,fooObject[].class);
You can read it like this:
JsonNode jsonNode = mapper.readTree(json);
if (jsonNode.isArray()) {
fooObject[] newFoo = mapper.readValue(jsonNode,fooObject[].class);
...
} else {
fooObject newFoo = mapper.readValue(jsonNode,fooObject.class);
....
}
