So im trying to create and json with 4 of the same objects in it but cant seem to get it to work using ArduinoJson 6, version 5 looks easier to use with .createObject but curious why they removed it in 6 cause there must still be a way to do it. Is there a way to do it or do i have to downgrade to version 5?
What i want it to look like:
{
"Spot":[
{
"LocationId":"673d855c-9f66-4e49-8b2c-737e829d880c",
"SpotId":"1",
"Occupied":"Empty"
},
{
"LocationId":"673d855c-9f66-4e49-8b2c-737e829d880c",
"SpotId":"2",
"Occupied":"Empty"
},
{
"LocationId":"673d855c-9f66-4e49-8b2c-737e829d880c",
"SpotId":"3",
"Occupied":"Empty"
},
{
"LocationId":"673d855c-9f66-4e49-8b2c-737e829d880c",
"SpotId":"4",
"Occupied":"Empty"
}
]
}
My Code:
char json_string[256];
StaticJsonDocument<256> carparkResponse;
JsonObject spot1 = carparkResponse.createNestedObject("Spot");
spot1["LocationId"] = LOCATION_ID;
spot1["SpotId"] = "1";
spot1["Occupied"] = occupied1.isOccupied();
JsonObject spot2 = spot1.createNestedObject();
spot2["LocationId"] = LOCATION_ID;
spot2["SpotId"] = "2";
spot2["Occupied"] = occupied2.isOccupied();
JsonObject spot3 = spot2.createNestedObject();
spot3["LocationId"] = LOCATION_ID;
spot3["SpotId"] = "3";
spot3["Occupied"] = occupied3.isOccupied();
JsonObject spot4 = spot3.createNestedObject();
spot4["LocationId"] = LOCATION_ID;
spot4["SpotId"] = "4";
spot4["Occupied"] = occupied4.isOccupied();
serializeJson(carparkResponse, json_string);
Serial.println(json_string);
So I found the Json builder that fixed my issue in case anyone else has to make any json's https://arduinojson.org/v6/assistant/#/step1

My C# MVC5 Razor page returns a Newtonsoft json link object to my controller (the "1" before \nEdit |" indicates that the checkbox is checked:
"{\"0\": [\"6146\",\"Kimball\",\"Jimmy\",\"General Funny Guy\",\"277\",\"Unite\",\"Jun 2019\",\"\",\"\",\"1\",\"\nEdit |\nDetails\n\n \n\"],\"1\": [\"6147\",\"Hawk\",\"Jack\",\"\",\"547\",\"Painters\",\"Jun 2019\",\"\",\"\",\"on\",\"\nEdit |\nDetails\n\n \n\"]}"
How do I parse this?
I am using a WebGrid to view and I want to allow the users to update only the lines they want (by checking the checkbox for that row), but it doesn't include an id for the 's in the dom. I figured out how to pull the values, but not the fieldname: "Last Name" , value: "Smith"... I only have the value and can't seem to parse it... one of my many failed attempts:
public ActoinResult AttMods(string gridData)
{
dynamic parsedArray = JsonConvert.DeserializeObject(gridData);
foreach (var item in parsedArray)
{
string[] itemvalue = item.Split(delimiterChars);
{
var id = itemvalue[0];
}
}
I finally sorted this one out..If there is a more dynamic answer, please share... I'll give it a few days before I accept my own (admittedly clugy) answer.
if(ModelState.IsValid)
{
try
{
Dictionary <string,string[]> log = Newtonsoft.Json.JsonConvert.DeserializeObject<Dictionary<string, string[]>>(gridData);
foreach (KeyValuePair<string,string[]> keyValue in log)
{
if (keyValue.Value[9] == "1")//Update this row based on the checkbox being checked
{
var AttendeeID = keyValue.Value[0];
int intAttendeeID = 0;
if (int.TryParse(AttendeeID, out intAttendeeID))//Make sure the AttendeeID is valid
{
var LName = keyValue.Value[1];
var FName = keyValue.Value[2];
var Title = keyValue.Value[3];
var kOrgID = keyValue.Value[4];
var Org = keyValue.Value[5];
var City = keyValue.Value[7];
var State = keyValue.Value[8];
var LegalApproval = keyValue.Value[9];
tblAttendee att = db.tblAttendees.Find(Convert.ToInt32(AttendeeID));
att.FName = FName;
att.LName = LName;
att.Title = Title;
att.kOrgID = Convert.ToInt32(kOrgID);
att.Organization = Org;
att.City = City;
att.State = State;
att.LegalApprovedAtt = Convert.ToBoolean(LegalApproval);
}
}
}
db.SaveChanges();
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}
}
You can avoid assigning the var's and just populate the att object with the KeyValue.Value[n] value, but you get the idea.
Using Node js and Sequelize ORM, i'm getting a data set. I need to add a new attribute to received data and send it to client side. This is what i tried.
Code Block 1
var varAddOns = { "id" : 5, "Name" : "Cheese"};
global.meal.findOne(
{
where: { id: 5 }
}).then(varMeal => {
var obj = {};
obj = varMeal;
obj.addons = varAddOns;
res.send(obj);
});
It returns a json like below. (Actually it does not contain "addons" data)
Code Block 2
{
"id": 12,
"mealName": "Burger",
"description": "Oily food",
}
but actually what i want is,
Code Block 3
{
"id": 12,
"mealName": "Burger",
"description": "Oily food",
"addons" : {
"id" : 5,
"Name" : "Cheese"
}
}
I tried something like below and it also wont work. (It returns same json as "Code Block 2'.)
Code Block 4
var newJson = {};
newJson = JSON.stringify(varMeal);
newJson['addons'] = varAddOns;
var retVal = JSON.parse(newJson);
res.send(retVal);
Can you help me to figure out, where the issue is?
EDIT
Code Block 5
var newJson = {};
newJson = varMeal;
newJson['addons'] = varAddOn;
var retVal = newJson;// JSON.parse(newJson);
res.send(retVal);
I tried 'Code block 5' as well. Same result comes out as 'Code block 2'. When I use JSON.parse(newJson), it was thrown an error. (Error is Unexpected token o in JSON at position 1)
You need to call .get on your model instance, and then attach extra properties to it:
var varAddOns = { "id" : 5, "Name" : "Cheese"};
global.meal.findOne(
{
where: { id: 5 }
}).then(varMeal => {
var obj = {};
obj = varMeal.get();
obj.addons = varAddOns;
res.send(obj);
});
A few things:
When you call findOne, Sequelize return a model instance, not a plain JS object with your data.
If you want to add extra properties to send to your user, you will first need to convert your model instance to a JS object with your data. You can do this by calling varMeal.get(). From there, you can add extra properties to it.
There is no need to prepend your variables with "var". It would be better to simply name your variable meal
you need the JSON to be an object when you are declaring newJson['addons'] as a nested object
Have you tried (in code block 4) not stringifying varMeal?
iv'e been trying for few days to get parameters from specific json structure with no success so far. I have a NSDictionary that get json data (i need the mToken and data from mHeader for example)
{
"$id" = 1;
mHeaders = (
{
"$id" = 4;
mPoints = 0;
mRealLeagueId = 57172a6e2276fe28bcf0d91c;
mTeamId = 57172a762276fe28bcf0e053;
mTeamLogo = avatar;
mTeamName = "Hungry Animals";
}
);
mToken = "5k8ziTBn0G5Gozs7qz68LCLBfLSgymOcLwRshMax1Q5pZi4bx6hbEOFgupoXrBNNGzsWosLs6KPsK6cG1kk/9o5778Y7JEKfo3CAPXS7qAg=";
mUser = {
"$id" = 2;
mAge = 42;
mCreateDate = "2016-04-20T07:06:30.507Z";
mEmail = "email0#gmail.com";
mFirstName = Alesandro;
mGender = 1;
mId = 57172a762276fe28bcf0e06d;
mLastLogin = "2016-04-21T07:20:40.402Z";
mLastName = Zohar;
mLogo = avatar;
mNick = "Big Boss 0";
mRegion = Global;
mTeams = (
{
"$id" = 3;
mRealLeagueId = 57172a6e2276fe28bcf0d91c;
mTeamId = 57172a762276fe28bcf0e053;
}
);
mTokens = 9644998;
};
}
So you have a dictionary after parsing the json. You need mToken which in root level of the json data, you can simply get the value by
jsonDict["mToken"]
Your mHeader is an array of dictionary so for getting the value, Do like this
for dict in jsonDict["mHeaders"] as! Array<NSDictionary> {
print(dict["mRealLeagueId"]) //prints 57172a6e2276fe28bcf0d91c
print(dict["mTeamId"]) //57172a762276fe28bcf0e053
}
Hope this helps
This is my response ... My dictnary name is "msg"
{
Result = {
Data = {
engine = {
service = {
data = (

checked = 1;
field = 1;

I try to to store the data like this
var arrayMain : NSMutableArray = msg.valueForKey("Result")?.valueForKey("Data") as NSMutableArray
My problem is i got "EXC_BAD_ACCESS" error While running ... Am also check allocation of array ... I try to store it in NSMutableDictionary its work perfectly ... How can i store this response in NSMutableArray ?
If you look carefully at the response data structure you'll see the problem.
This first operation: msg.valueForKey("Result") would return an dictionary with two key/values; a "Data" dictionary, and "Status" string.
Your second operation .valueForKey("Data") would return a dictionary with two key/values; an "Engine and "Tact" dictionary.
Because it's a dictionary, you can create a dictionary from it, which is what you said worked, or you're going to have to rethink how you want to store if if indeed you want it in an array, but you can't create an array directly from a dictionary - they are different data structures.
You cannot assign Dictionary object to Array, that's why it is giving the error.
But you can store that dictionary to array as:
var arrayMain : NSMutableArray = NSMutableArray()
arrayMain.addObject(msg.valueForKey("Result")?.valueForKey("Data"))
I am getting the following data in JSON format by the Facebook graph API. However it looks like it is in invalid JSON format. The JSON formatter says that the error is in line 1. What is this error ?
