有没有一种方法可以反序列化Elasticsearch Nest搜索查询？

elasticsearchnest

在使用Nest构建Elasticsearch查询时，我希望能够查看发送到Elasticsearch的JSON版本。这可能吗？我想是某种反序列化器。

这是我后续问题的信息：

是的，您可以像这样使用ElasticClient公开的序列化器：

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

你也可以直接使用Newtonsoft或任何JSON库来序列化查询对象。然而，使用ElasticClient中的序列化器（本质上是包装Newtonsoft）将为您提供NEST将生成的确切JSON。
要了解更多详细信息，请查看NEST中的单元测试，特别是this。
我尝试了类似的东西，以查看为什么我的索引没有按照我预期的那样被创建。它看起来还不错，直到我到达响应对象，它只是一堆垃圾字符串。有什么想法吗？请参见我上面的编辑。 - bigerock
那一串垃圾实际上是您的JSON请求，经过Base64编码。 - Greg Marzouka
好的 - 有没有一种方法可以查看它的解码？我真的很紧张。今天早些时候它都正常工作。我不知道我做了什么 - 我真的没想到我做了什么 - 但现在它根本不关注我的映射，而是自己进行简单的动态映射。我一直在注释掉所有内容以查看可能是什么，但没有运气。救命啊！ :) - bigerock
好的 - 我弄清楚了，我需要删除整个索引，而不仅仅是类型，并重新开始。关于解码的另一个问题仍然有效。 - bigerock

顺便说一下，这段代码对我来说无法工作。出现错误...检测到类型为“Nest.SearchResponse”的属性“response”存在自引用循环。 - bigerock
我已经为您修复了这个问题；使用新的SerializeToString方法替代Serialize。 - Patrick Szalapski

我使用SearchDescriptor进行复杂查询，代码如下：
SearchDescriptor<T> sd = new SearchDescriptor<T>()
.From(0).Size(100)
    .Query(q => q
        .Bool(t => t
            .Must(u => u
                .Bool(v => v
                    .Should(
                        ...
                    )
                )
            )
        )
    );

然后得到了反序列化后的JSON，如下所示：

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

这很烦人，NEST库应该有一些能够从请求中输出JSON的东西。然而，以下方法对我有效：

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

NEST库版本：2.0.0.0。 希望更新的版本可以有更简单的方法来获取此信息。

将以下代码添加到您的 WebApiConfig.cs 文件中：
public static void Register(HttpConfiguration config)
{
    ...
    // ignore circular reference globally
    config.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;
    ...
}

然后你应该能够像这样做：

// 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);
    ...
}

对于 Nest 5.3.0：

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