Gibt es eine Möglichkeit, Elasticsearch Nest-Suchanfrage zu deserialisieren?

Question

Beim Erstellen meiner Elasticsearch-Abfrage mithilfe von Nest möchte ich die JSON-Version dessen anzeigen können, was an Elasticsearch gesendet wird. Ist das möglich? eine Art Deserializer, nehme ich an.

hier ist die Info für meine Follow-up-Frage:

Answer 1

Yup. Sie können die Serializer verwenden, die von ElasticClient wie folgt ausgesetzt:

var query = Nest.Query<SomeObject>... 
var json = Client.Serializer.SerializeToString(query); 

Sie Newtonsoft was das betrifft direkt oder über JSON-Bibliothek Abfrage-Objekt verwenden, können auch serialisiert. Wenn Sie jedoch den Serializer in ElasticClient verwenden (der Newtonsoft im Wesentlichen umschließt), erhalten Sie genau den JSON, den NEST generiert.

Checkout, wie die Komponententests in NEST für weitere Details durchgeführt werden, speziell this.

Answer 2

Fügen Sie diese auf Ihre WebApiConfig.cs:

public static void Register(HttpConfiguration config) 
{ 
    ... 
    // ignore circular reference globally 
    config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore; 
    ... 
} 

Dann sollten Sie in der Lage sein, so etwas zu tun:

// Return raw 
var esObj = await _client.SearchAsync<object>(searchRequest); 

// more specific deserialization using Newtonsoft.Json example 
foreach (var hit in esObj.Hits) 
{ 
    var myObj = JsonConvert.DeserializeObject<MyObject>(hit.xxx); 
    ... 
} 

Answer 3

Wenn die obige Antwort nicht funktioniert, oder Sie wollen ein Einfacher, ich habe einen anderen Weg hier auf, was ist wahrscheinlich ein Duplikat, (aber anders formuliert) Frage: https://stackoverflow.com/a/31247636/261405

Answer 4

Für Nest 5.3.0:

 var memoryStream = new System.IO.MemoryStream(); 
     client.Serializer.Serialize(query, memoryStream); 
     var jsonQuery = System.Text.Encoding.UTF8.GetString(memoryStream.ToArray()); 

Answer 5

I verwendet SearchDescriptor wie dies für eine komplexe Abfrage:

SearchDescriptor<T> sd = new SearchDescriptor<T>() 
.From(0).Size(100) 
    .Query(q => q 
     .Bool(t => t 
      .Must(u => u 
       .Bool(v => v 
        .Should(
         ... 
        ) 
       ) 
      ) 
     ) 
    ); 

und bekam die entserialisierten JSON wie folgt aus:

{ 
    "from": 0, 
    "size": 100, 
    "query": { 
    "bool": { 
     "must": [ 
     { 
      "bool": { 
      "should": [ 
       ... 
      ] 
      } 
     } 
     ] 
    } 
    } 
} 

Es war ärgerlich, sollte NEST Bibliothek etwas haben, das spuckt JSON aus Anfrage heraus. Dies funktionierte jedoch für mich:

using (MemoryStream mStream = new MemoryStream()) { 
    client.Serializer.Serialize(sd, mStream); 
    Console.WriteLine(Encoding.ASCII.GetString(mStream.ToArray())); 
} 

NEST Bibliothek Version: 2.0.0.0. Neuere Version möglicherweise eine einfachere Methode, um dies zu erhalten (hoffentlich).
