serialize query from Nest client elastic search 2.3

Question

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));

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.

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);

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);

Whilst developing it may be useful to log out all requests and responses.

Excellent, thanks very much. (I tried to upvote but I need a score of 15) – zappa Apr 12 '16 at 07:29
No problem. Feel free to upvote and accept the answer :) – Russ Cam Apr 12 '16 at 07:30
Unfortunately this relies on my calling the Search method in order to see what's in my request, in my original query I could see what I was ABOUT to send without actually sending it, is there a way to do this? – zappa Apr 20 '16 at 09:57

Yes, pass your request to `client.Serializer.SerializeToString(request);` for json string or `client.Serializer.SerializeToBytes(request)` for a byte array – Russ Cam Apr 20 '16 at 10:00

Note that the `SerializeToString` and `SerializeToBytes` are extension methods and you need a `using Elasticsearch.Net;` – gwenzek Jun 16 '16 at 10:12

Serialize method now requires stream, on which it will write raw json query - Working properly For Nest 5.3.0 :

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