Analizza JSON in C #
Domanda
Sto cercando di analizzare alcuni dati JSON dall'API di ricerca AJAX di Google. Ho questo URL e vorrei piace scomporlo in modo che i risultati vengano visualizzati. Al momento ho scritto questo codice, ma sono piuttosto perso riguardo a cosa fare dopo, anche se ci sono un certo numero di esempi là fuori con stringhe JSON semplificate.
Essendo nuovo in C # e .NET in generale, ho avuto difficoltà a ottenere un vero output di testo per la mia pagina ASP.NET, quindi mi è stato consigliato di provare JSON.NET. Qualcuno potrebbe indirizzarmi nella giusta direzione semplicemente scrivendo un po 'di codice che prenderà JSON dall'API di Google AJAX Search e lo stamperà sullo schermo?
MODIFICA: TUTTO FISSO! Tutti i risultati funzionano bene. Grazie ancora Dreas Grech!

Json.NET funziona utilizzando lo stesso JSON e le classi dell'esempio precedente.
GoogleSearchResults g1 = JsonConvert.DeserializeObject<GoogleSearchResults>(json);

Soluzione
[Aggiornamento]
Ho appena capito perché non stavi ricevendo risultati ... hai una linea mancante nel tuo metodo Deserialize
. Ti stavi dimenticando di assegnare i risultati al tuo obj
:
public static T Deserialize<T>(string json)
{
using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));
return (T)serializer.ReadObject(ms);
}
}
Inoltre, solo per riferimento, ecco il metodo Serialize
:
public static string Serialize<T>(T obj)
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
using (MemoryStream ms = new MemoryStream())
{
serializer.WriteObject(ms, obj);
return Encoding.Default.GetString(ms.ToArray());
}
}
Modifica
Se vuoi usare Json.NET qui ci sono i metodi Serialize / Deserialize equivalenti al codice sopra ..
Deserialize:
JsonConvert.DeserializeObject<T>(string json);
Serialize:
JsonConvert.SerializeObject(object o);
Questo fa già parte di Json.NET, quindi puoi semplicemente chiamarli sulla classe JsonConvert.
Link: Serializzazione e deserializzazione JSON con Json.NET
Ora, il motivo per cui stai ricevendo StackOverflow è a causa delle tue Proprietà
.
Prendi ad esempio questo:
[DataMember]
public string unescapedUrl
{
get { return unescapedUrl; } // <= this line is causing a Stack Overflow
set { this.unescapedUrl = value; }
}
Si noti che nel getter
, si sta restituendo la proprietà effettiva (ovvero il getter della proprietà si chiama ripetutamente), e quindi si sta creando una ricorsione infinita.
Le proprietà (in 2.0) devono essere definite in questo modo:
string _unescapedUrl; // <= private field
[DataMember]
public string unescapedUrl
{
get { return _unescapedUrl; }
set { _unescapedUrl = value; }
}
Si dispone di un campo privato e quindi si restituisce il valore di quel campo nel getter e si imposta il valore di quel campo nel setter.
A proposito, se stai usando il Framework 3.5, puoi semplicemente farlo ed evitare i campi di supporto e lasciare che il compilatore si occupi di quello:
public string unescapedUrl { get; set;}
Altri suggerimenti
La tua classe di dati non corrisponde all'oggetto JSON. Usa questo invece:
[DataContract]
public class GoogleSearchResults
{
[DataMember]
public ResponseData responseData { get; set; }
}
[DataContract]
public class ResponseData
{
[DataMember]
public IEnumerable<Results> results { get; set; }
}
[DataContract]
public class Results
{
[DataMember]
public string unescapedUrl { get; set; }
[DataMember]
public string url { get; set; }
[DataMember]
public string visibleUrl { get; set; }
[DataMember]
public string cacheUrl { get; set; }
[DataMember]
public string title { get; set; }
[DataMember]
public string titleNoFormatting { get; set; }
[DataMember]
public string content { get; set; }
}
Inoltre, non è necessario creare un'istanza della classe per ottenere il suo tipo per la deserializzazione:
public static T Deserialise<T>(string json)
{
using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
var serialiser = new DataContractJsonSerializer(typeof(T));
return (T)serialiser.ReadObject(ms);
}
}
Ho trovato questo approccio che analizza JSON in un oggetto dinamico , estende un DynamicObject
e JavascriptConverter
per trasformare la stringa in un oggetto.
DynamicJsonObject
public class DynamicJsonObject : DynamicObject
{
private IDictionary<string, object> Dictionary { get; set; }
public DynamicJsonObject(IDictionary<string, object> dictionary)
{
this.Dictionary = dictionary;
}
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
result = this.Dictionary[binder.Name];
if (result is IDictionary<string, object>)
{
result = new DynamicJsonObject(result as IDictionary<string, object>);
}
else if (result is ArrayList && (result as ArrayList) is IDictionary<string, object>)
{
result = new List<DynamicJsonObject>((result as ArrayList).ToArray().Select(x => new DynamicJsonObject(x as IDictionary<string, object>)));
}
else if (result is ArrayList)
{
result = new List<object>((result as ArrayList).ToArray());
}
return this.Dictionary.ContainsKey(binder.Name);
}
}
Convertitore
public class DynamicJsonConverter : JavaScriptConverter
{
public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer)
{
if (dictionary == null)
throw new ArgumentNullException("dictionary");
if (type == typeof(object))
{
return new DynamicJsonObject(dictionary);
}
return null;
}
public override IDictionary<string, object> Serialize(object obj, JavaScriptSerializer serializer)
{
throw new NotImplementedException();
}
public override IEnumerable<Type> SupportedTypes
{
get { return new ReadOnlyCollection<Type>(new List<Type>(new Type[] { typeof(object) })); }
}
}
Utilizzo ( sample json ):
JavaScriptSerializer jss = new JavaScriptSerializer();
jss.RegisterConverters(new JavaScriptConverter[] { new DynamicJsonConverter() });
dynamic glossaryEntry = jss.Deserialize(json, typeof(object)) as dynamic;
Console.WriteLine("glossaryEntry.glossary.title: " + glossaryEntry.glossary.title);
Console.WriteLine("glossaryEntry.glossary.GlossDiv.title: " + glossaryEntry.glossary.GlossDiv.title);
Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.ID: " + glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.ID);
Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.para: " + glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.para);
foreach (var also in glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.GlossSeeAlso)
{
Console.WriteLine("glossaryEntry.glossary.GlossDiv.GlossList.GlossEntry.GlossDef.GlossSeeAlso: " + also);
}
Questo metodo deve restituire true, altrimenti genererà un errore. Per esempio. puoi generare un errore se non esiste una chiave.
Restituendo true
e svuotando risultato
restituirà un valore vuoto anziché generare un errore.
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
if (!this.Dictionary.ContainsKey(binder.Name))
{
result = "";
}
else
{
result = this.Dictionary[binder.Name];
}
if (result is IDictionary<string, object>)
{
result = new DynamicJsonObject(result as IDictionary<string, object>);
}
else if (result is ArrayList && (result as ArrayList) is IDictionary<string, object>)
{
result = new List<DynamicJsonObject>((result as ArrayList).ToArray().Select(x => new DynamicJsonObject(x as IDictionary<string, object>)));
}
else if (result is ArrayList)
{
result = new List<object>((result as ArrayList).ToArray());
}
return true; // this.Dictionary.ContainsKey(binder.Name);
}
Penso solo che l'intero esempio sarebbe utile. Questo è l'esempio per questo problema.

Ho provato a usare il codice sopra ma non ha funzionato. La struttura JSON restituita da Google è molto diversa e c'è una mancanza molto importante nella funzione di supporto: una chiamata a DataContractJsonSerializer.ReadObject ()
che in realtà deserializza i dati JSON nell'oggetto.
Ecco il codice che FUNZIONA nel 2011:
using System;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using System.IO;
using System.Text;
using System.Collections.Generic;
namespace <YOUR_NAMESPACE>
{
public class JSONHelper
{
public static T Deserialise<T>(string json)
{
T obj = Activator.CreateInstance<T>();
MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));
DataContractJsonSerializer serialiser = new DataContractJsonSerializer(obj.GetType());
obj = (T)serialiser.ReadObject(ms);
ms.Close();
return obj;
}
}
public class Result
{
public string GsearchResultClass { get; set; }
public string unescapedUrl { get; set; }
public string url { get; set; }
public string visibleUrl { get; set; }
public string cacheUrl { get; set; }
public string title { get; set; }
public string titleNoFormatting { get; set; }
public string content { get; set; }
}
public class Page
{
public string start { get; set; }
public int label { get; set; }
}
public class Cursor
{
public string resultCount { get; set; }
public Page[] pages { get; set; }
public string estimatedResultCount { get; set; }
public int currentPageIndex { get; set; }
public string moreResultsUrl { get; set; }
public string searchResultTime { get; set; }
}
public class ResponseData
{
public Result[] results { get; set; }
public Cursor cursor { get; set; }
}
public class GoogleSearchResults
{
public ResponseData responseData { get; set; }
public object responseDetails { get; set; }
public int responseStatus { get; set; }
}
}
Per ottenere il contenuto del primo risultato, fai:
GoogleSearchResults googleResults = new GoogleSearchResults();
googleResults = JSONHelper.Deserialise<GoogleSearchResults>(jsonData);
string contentOfFirstResult = googleResults.responseData.results[0].content;
Grazie a tutti per il vostro aiuto. Questa è la mia versione finale e funziona grazie al tuo aiuto combinato! Sto solo mostrando le modifiche che ho apportato, tutto il resto è tratto da il lavoro di Joe Chung
