从Nest客户端进行序列化查询弹性搜索2.3 [英] serialize query from Nest client elastic search 2.3

问题描述

由于将我的Nest客户端升级到2.2.1，我无法看到我提交给我的弹性搜索客户端（现在是2.3.0版本）的查询。
我曾经使用这一行：

Since upgrading my Nest client to 2.2.1 I'm unable see the query I'm submitting to my elastic search client (now version 2.3.0). I used to use this line:

string searchJson = Encoding.UTF8.GetString(client.Serializer.Serialize(myQueryHere));  

但是，此方法现在返回void而不是以前使用的JSON。
ConnectionStatus也不存在，所以我不能再看到我发送的json，有人知道一个方法吗？ CallDetails.RequestBodyInBytes可用，但返回null。

But this method now returns void instead of the JSON it used to. ConnectionStatus also doesn't exist so I can no longer see the json i'm sending, does anyone know of a way? CallDetails.RequestBodyInBytes is available but that returns null.

推荐答案

查看连接时NEST 2.x的文档。 CallDetails.RequestBodyInBytes 将 null 除非您设置 .DisableDirectStreaming（）传递给的构造函数ElasticClient

Take a look at the documentation for NEST 2.x on Connecting. CallDetails.RequestBodyInBytes will be null unless you set .DisableDirectStreaming() on ConnectionSettings that is passed to the constructor of ElasticClient

var connectionPool = new SingleNodeConnectionPool(new Uri("http://localhost:9200"));  
var settings = new ConnectionSettings(connectionPool) 
    .DisableDirectStreaming();

var client = new ElasticClient(settings);

现在，请求和响应字节的副本将在响应CallAttribute上显示

now a copy of the request and response bytes will be exposed on the response CallDetails

var response = client.Search<Document>();

var requestJson = Encoding.UTF8.GetString(response.CallDetails.RequestBodyInBytes);
var responseJson = Encoding.UTF8.GetString(response.CallDetails.ResponseBodyInBytes);

发展中可能有用的是注销所有请求和响应。
