Analyse de la réponse de l'api Json rest en C #

J'essaie de tirer une valeur d'une réponse json api de repos en utilisant C #.

J'ai le code suivant:

client.BaseUrl = "https://api.cloud.appcelerator.com";
request.Resource = "/v1/chats/create.json?key=" + cac.AppCode.ToString();
request.Method = Method.POST;
request.AddUrlSegment("appkey", "key");
var response = client.Execute(request);

Dans le message "réponse", j'ai obtenu un contenu json comme suit:

{
  "meta": {
    "code": 200,
    "status": "ok",
    "method_name": "createChatMessage"
  },
  "response": {
    "chats": [
      {
        "id": "521cfcd840926a0b3500449e",
        "created_at": "2013-08-27T19:24:08+0000",
        "updated_at": "2013-08-27T19:24:08+0000",
        "message": " join to the chat group, welcome …",
        "from": {
          "id": "520f41e125e74b0b2400130a",
          "first_name": "Administrator",
          "created_at": "2013-08-17T09:26:57+0000",
          "updated_at": "2013-08-27T19:23:10+0000",
          "external_accounts": [

          ],
          "email": "[email protected]",
          "confirmed_at": "2013-08-17T09:26:57+0000",
          "username": "admin",
          "admin": "true",
          "stats": {
            "photos": {
              "total_count": 0
            },
            "storage": {
              "used": 0
            }
          }
        },
        "chat_group": {
          "id": "521cfcd840926a0b3500449d",
          "created_at": "2013-08-27T19:24:08+0000",
          "updated_at": "2013-08-27T19:24:08+0000",
          "message": " join to the chat group, welcome …",
          "participate_users": [
            {
              "id": "520f41e125e74b0b2400130a",
              "first_name": "Administrator",
              "created_at": "2013-08-17T09:26:57+0000",
              "updated_at": "2013-08-27T19:23:10+0000",
              "external_accounts": [

              ],
              "email": "[email protected]",
              "confirmed_at": "2013-08-17T09:26:57+0000",
              "username": "admin",
              "admin": "true",
              "stats": {
                "photos": {
                  "total_count": 0
                },
                "storage": {
                  "used": 0
                }
              }
            }
          ]
        }
      }
    ]
  }
}

Comment extraire la valeur imbriquée suivante de "id": "521cfcd840926a0b3500449e" du message de résultat de réponse json renvoyé?

J'utilise C #.

1> Ajoutez ce namspace. using Newtonsoft.Json.Linq;

2> utilisez ce code source.

JObject joResponse = JObject.Parse(response);                   
JObject ojObject = (JObject)joResponse["response"];
JArray array= (JArray)ojObject ["chats"];
int id = Convert.ToInt32(array[0].toString());

  1. Créez des classes qui correspondent à vos données,
  2. puis utilisez JSON.NET pour convertir les données JSON en objets C # normaux.

Étape 1: un excellent outil - http://json2csharp.com/ - les résultats générés par celui-ci sont ci-dessous

Étape 2: JToken.Parse(...).ToObject<RootObject>().

public class Meta
{
    public int code { get; set; }
    public string status { get; set; }
    public string method_name { get; set; }

}

public class Storage
{
    public int used { get; set; }
}

public class Stats
{
    public Photos photos { get; set; }
    public Storage storage { get; set; }
}

public class From

Créez une classe C # qui correspond à votre Json et utilisez Newsoft JsonConvert Pour le désérialiser.

Par exemple:

public Class MyResponse
{
    public Meta Meta { get; set; }
    public Response Response { get; set; }
}
