问题描述

现在，Elastic Search正在添加空值，如图所示，我希望看到在Elastic Search内部添加完整的json对象作为文档，这样我就可以对其进行搜索

代码

    public async Task<CreateResponse> CreateDocumentAndIndex<T>(T document, string index, Type objectType) where T : class
            {
                _client = CreateElasticClient();
      var serializedObject = JsonConvert.SerializeObject(document, Formatting.None,
                       new JsonSerializerSettings()
                       {
                           ReferenceLoopHandling = ReferenceLoopHandling.Ignore
                       });
          var elasticValues = new ElasticSeachValues
                {
                    values = JObject.Parse(serializedObject)
                };
    
                Console.WriteLine(elasticValues.values);
    
                var getIndexResponse = await _client.IndexAsync(elasticValues, idx => idx.Index(index.ToLower()));
                }
    }

      public class ElasticSeachValues 
        {
            public JObject values { get; set; }
        }

我尝试在Elastic Search中将其添加为带索引的文档。IndexAsync方法返回201，当我在Kibana中查看它时，它显示空结果，如下所示：如何添加完整的对象/类？

   private ElasticClient CreateElasticClient()
        {
            var settings = new ConnectionSettings(new Uri("http://localhost:9200/"));

            var client = new ElasticClient(settings);          
            return client;
        }

此客户端只是来自Nest Library的弹性搜索客户端https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/nest.html

推荐答案

您还需要引用NEST.JsonNetSerializer Nuget包，并在如下所示的连接设置中添加JsonNetSerializer：

     var pool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));
    
                var connectionSettings =
          new ConnectionSettings(pool, sourceSerializer: JsonNetSerializer.Default);
    
                var client = new ElasticClient(connectionSettings);          
                return client;
