Je travaille avec SwiftType Elastic Search + C # et rencontre un problème de désérialisation de la réponse car SwiftType renvoie tous les champs en tant qu'objets avec une propriété raw
( https: // swiftype .com/documentation/app-search/api/search ) par exemple:
{
"meta": {
"warnings": [],
"page": {
"current": 1,
"total_pages": 1,
"total_results": 2,
"size": 10
},
"request_id": "6887a53f701a59574a0f3a7012e01aa8"
},
"results": [
{

},
"accounts_balance_ach": {

},
"accounts_balance_pending": {

},

"raw": "[email protected]"
},
"accounts_count": {
"raw": 6.0
},

},

}
},
{

},
"accounts_balance_ach": {

},
"accounts_balance_pending": {

},

}
]
}
J'ai besoin de mapper chaque clé à sa valeur, par exemple results [0] .email = "[email protected]";
J'ai vu un option prometteuse avec des convertisseurs personnalisés mais je veux m'assurer qu'il n'y a pas de manière plus dynamique de le faire avant d'adopter l'approche verbeuse.
Je suggère d'utiliser la classe JsonPathConverter
trouvée dans Puis-je spécifier un chemin dans un attribut pour mapper une propriété de ma classe à une propriété enfant dans mon JSON? . Cela vous permettra de déclarer une classe Result
fortement typée, puis de mapper facilement chacune des propriétés à la valeur de la valeur enfant raw
respective dans le JSON sans avoir à déclarer une tonne de maladroit classes à propriété unique.
Déclarez votre modèle comme indiqué ci-dessous. Notez que la classe Result
a besoin d'un [JsonConverter]
attribut dessus pour le lier au JsonPathConverter
(sinon les chemins de propriété ne fonctionneront pas et vous obtiendrez des valeurs par défaut dans vos propriétés).
public class RootObject
{
public List<Result> results { get; set; }
}
[JsonConverter(typeof(JsonPathConverter))]
public class Result
{
[JsonProperty("phone.raw")]
public string Phone { get; set; }
[JsonProperty("accounts_balance_ach.raw")]
public decimal AccountsBalanceAch { get; set; }
[JsonProperty("accounts_balance_pending.raw")]
public decimal AccountsBalancePending { get; set; }
[JsonProperty("email.raw")]
public string Email { get; set; }
[JsonProperty("accounts_count.raw")]
public decimal AccountsCount { get; set; }
[JsonProperty("id.raw")]
public string Id { get; set; }
[JsonProperty("display_name.raw")]
public string DisplayName { get; set; }
[JsonProperty("type.raw")]
public string Type { get; set; }
[JsonProperty("advisor_email.raw")]
public string AdvisorEmail { get; set; }
[JsonProperty("created_at.raw")]
public string CreatedAt { get; set; }
[JsonProperty("source.raw")]
public string Source { get; set; }
[JsonProperty("accounts_balance.raw")]
public decimal AccountsBalance { get; set; }
[JsonProperty("accounts_donations.raw")]
public decimal AccountsDonations { get; set; }
[JsonProperty("advisor_name.raw")]
public string AdvisorName { get; set; }
[JsonProperty("_meta.score")]
public decimal MetaScore { get; set; }
}
Ensuite, vous pouvez simplement désérialiser comme d'habitude:
var root = JsonConvert.DeserializeObject<RootObject>(json);
Voici une démonstration de travail: https://dotnetfiddle.net/wYxwIF
La manière la plus dynamique pour vous serait d'utiliser La classe Newtonsoft JObejct .
Il analysera votre chaîne JSON dans un objet JSON que vous pourrez utiliser, c'est-à-dire si vous n'avez pas de modèle correspondant et que vous devez créer un objet JSON dynamique.
Par exemple :
string json = "{
"meta": {
"warnings": [],
"page": {
"current": 1,
"total_pages": 1,
"total_results": 2,
"size": 10
},

},

}"
JObject result = JObject.Parse(json);
result
est maintenant un objet JSON et vous pouvez accéder à ses propriétés.
Vous pouvez utiliser ce qui suit link pour convertir json en classe C #. Vous pouvez ensuite utiliser Newtonsoft Json pour analyser:
var jsonMessage = "{ \"meta\": { \"warnings\": [], \"page\": { \"current\": 1, \"total_pages\": 1, \"total_results\": 2, \"size\": 10 }, \"request_id\": \"6887a53f701a59574a0f3a7012e01aa8\" }, \"results\": [{ \"phone\": { \"raw\": 3148304280.0 }, \"accounts_balance_ach\": { \"raw\": 27068128.71 }, \"accounts_balance_pending\": { \"raw\": \"46809195.64\" }, \"email\": { \"raw\": \"[email protected]\" }, \"accounts_count\": { \"raw\": 6.0 }, \"id\": { \"raw\": \"c98808a2-d7d6-4444-834d-2fe4f6858f6b\" }, \"display_name\": { \"raw\": \"The Johnstons\" }, \"type\": { \"raw\": \"Couple\" }, \"advisor_email\": { \"raw\": \"[email protected]\" }, \"created_at\": { \"raw\": \"2018-10-02T10:42:07+00:00\" }, \"source\": { \"raw\": \"event\" }, \"accounts_balance\": { \"raw\": 43629003.47 }, \"accounts_donations\": { \"raw\": 38012278.75 }, \"advisor_name\": { \"raw\": \"Cloyd Jakubowski\" }, \"_meta\": { \"score\": 0.42934617 } }, { \"phone\": { \"raw\": 2272918612.0 }, \"accounts_balance_ach\": { \"raw\": 35721452.35 }, \"accounts_balance_pending\": { \"raw\": \"35117465.2\" }, \"email\": { \"raw\": \"[email protected]\" }, \"accounts_count\": { \"raw\": 1.0 }, \"id\": { \"raw\": \"687af11f-0f73-4112-879c-1108303cb07a\" }, \"display_name\": { \"raw\": \"Kennith Johnston\" }, \"type\": { \"raw\": \"Individual\" }, \"advisor_email\": { \"raw\": \"[email protected]\" }, \"created_at\": { \"raw\": \"2018-10-02T16:16:02+00:00\" }, \"source\": { \"raw\": \"website\" }, \"accounts_balance\": { \"raw\": 23063874.19 }, \"accounts_donations\": { \"raw\": 33025175.79 }, \"advisor_name\": { \"raw\": \"Ernie Mertz\" }, \"_meta\": { \"score\": 0.39096162 } } ]}";
