Resolved Parse Complex Json

Hello everyone,
i have been working with a coworker with json in dynamoDB. when i try to do a query, DynamoDB showme the next json

Code (CSharp):

1. [
2.    {
3.       "n_request":"",
4.       "posicion":"",
5.       "velocidad":"",
6.       "client_id":"r2",
7.       "status":"free",
8.       "PartitionKey":3.0
9.    },
10.    {
11.       "n_request":"",
12.       "posicion":"",
13.       "velocidad":"",
14.       "client_id":"r1",
15.       "status":"free",
16.       "PartitionKey":2.0
17.    },
18.    {
19.       "n_request":"",
20.       "posicion":"",
21.       "velocidad":"",
22.       "client_id":"c2",
23.       "status":"free",
24.       "PartitionKey":1.0
25.    },
26.    {
27.       "n_request":"",
28.       "posicion":"",
29.       "velocidad":"",
30.       "client_id":"c1",
31.       "status":"free",
32.       "PartitionKey":0.0
33.    }
34. ]

i do the deserialisation with one simple json and works. but when i try to deserialize this complex json i can't. here are objects and C# code.

Code (CSharp):

1. public class JsonObjects
2. {
3.     public DockiData[] allDockiData;
4. }
5.  
6. [Serializable]
7. public class DockiData
8. {
9.     public string n_request;
10.     public string posicion;
11.     public float velocidad;
12.     public string client_id;
13.     public string status;
14.     public string PartitionKey;
15.     public int posX, posY;
16.     char[] deleteLetters = { '[', ']', ',' };
17.  
18.     public void SplitPos()
19.     {
20.         string[] positions = posicion.Split(deleteLetters, 4, StringSplitOptions.None);
21.         posX = int.Parse(positions[1]);
22.         posY = int.Parse(positions[2]);
23.     }
24. }

and in here i deserialize the json

Code (CSharp):

1.     IEnumerator RequestJson()
2.     {
3.         UnityWebRequest carInformation = UnityWebRequest.Get(url);
4.  
5.  
6.         yield return carInformation.SendWebRequest();
7.  
8.         if (carInformation.isHttpError || carInformation.isNetworkError)
9.         {
10.             Debug.Log(carInformation.error);
11.  
12.         }
13.         else
14.         {
15.             string json = carInformation.downloadHandler.text;
16.             print(json);
17.             clients = JsonUtility.FromJson<JsonObjects>(json);
18.  
19.  
20.        
21.  
22.          
23.         }
24.  
25.  
26.  
27.     }

when i run the project apear the next issue:

ArgumentException: JSON must represent an object type.
UnityEngine.JsonUtility.FromJson (System.String json, System.Type type) (at <0618d0873e03447096799ae90b4ad4f1>:0)

thanks for your help and regards.

 

your json is a naked array, which JsonUtility doesn't support. You must wrap it in a json object, as such:

Code (JavaScript):

1. {
2.   "allDockiData": [
3.     // your json array here
4.   ]
5. }

 

thanks it works.
