How to extract document id from response - ElasticSearch Java Low Level Rest Client

I'm indexing document without id into ElasticSearch using the following code:

Response response = restClient.performRequest(
            HttpPost.METHOD_NAME,
            "/posts/doc/",
            Collections.emptyMap(),
            entity);

I want to extract the document id that was generated by ElasticSearch from the response. Is there any way to do that?

response.getEntity().getContent() is InputStream object.

So, you could you BufferedReader also.

Try this:

BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
StringBuilder out = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
    out.append(line);
}
System.out.println(out.toString());

You need to read the response object for that response.getEntity().getContent().

If you are using Jackson, you can then deserialize the stream as a Map mapper.readValue(response.getEntity().getContent(), new TypeReference<Map<String, Object>>(){});

Then from the map, read the _id field.

Hope this helps.
