Java/RestClient Render/Dump/Log the BulkRequest issued

[ibexit]

We´re able to access the RequestBody sent by the client for searches - pretty easy.

But is there a way to have this for BulkRequests too? Or in other words: I need access to the _bulk payloads compiled/send by the java-rest-client and save them into files for reasons.

My Code:

     BulkRequest request = new BulkRequest();
        request.add(new IndexRequest("posts").id("1")
                .source(XContentType.JSON,"foo", "ba1"));
        request.add(new IndexRequest("posts").id("2")
                .source(XContentType.JSON,"foo", "bar2"));
        request.add(new IndexRequest("posts").id("3")
                .source(XContentType.JSON,"foo", "bar3"));

        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        OutputStreamStreamOutput osso = new OutputStreamStreamOutput(baos);

        request.writeTo(osso);
        String requestAsString = baos.toString("UTF-8");

The Output:

     ����   ����posts  _doc1 
{"foo":"ba1"} ��������     ��������     ����posts  _doc2 {"foo":"bar2"} ��������     ��������     ����posts  _doc3 {"foo":"bar3"} ��������     ��������   

Expected/Desired Output:

{ "index" : { "_index" : "posts", "_id" : "1" } }
{ "foo" : "bar1" }
{ "index" : { "_index" : "posts", "_id" : "2" } }
{ "foo" : "bar2" }
{ "index" : { "_index" : "posts", "_id" : "3" } }
{ "foo" : "bar3" }

Anyone eager to help? Thanks in advance!
