## In the **source code** of `Elasticsearch`, how it get the body of `_bulk request`?

Such as the following request:

```
curl -i -XPOST 'http://localhost:9200/_bulk/?pretty' -d '
{ "delete" : {"_index" : "test", "_type" : "employee", "_id" : "3" } }
{ "create" : {"_index" : "test", "_type" : "employee", "_id" : "3"} }
{ "first_name" : "Reka", "last_name" : "Downey", "age" : 22, "about" : "I like new things!", "interests" : ["sport", "read"] }
{ "index" : {"_index" : "test", "_type" : "employee"} }
{ "first_name" : "Lily", "last_name" : "Smith", "age" : 23, "about" : "I like swimming!", "interests" : ["swim"] }
{ "update" : {"_index" : "test", "_type" : "employee", "_id" : "3"} }
{ "docs" : {"age" : 24} }'

```

now the **question** is how `Elasticsearch` get the data in this request, which content is

> { "delete" : {"\_index" : "test", "\_type" : "employee", "\_id" : "3" } }  
> { "create" : {"\_index" : "test", "\_type" : "employee", "\_id" : "3"} }  
> { "first\_name" : "Reka", "last\_name" : "Downey", "age" : 22, "about" : "I like new things!", "interests" : ["sport", "read"] }  
> { "index" : {"\_index" : "test", "\_type" : "employee"} }  
> { "first\_name" : "Lily", "last\_name" : "Smith", "age" : 23, "about" : "I like swimming!", "interests" : ["swim"] }  
> { "update" : {"\_index" : "test", "\_type" : "employee", "\_id" : "3"} }  
> { "docs" : {"age" : 24} }

**the version of Elasticsearch is 2.3.1.**

we know that in the `org.elasticsearch.http.netty.HttpRequestHandler#messageReceived` method, we got the `HttpRequest` object; so now I want to know how to get the content through the `HttpRequest` object?

Request your kind help!  
Thanks!  
Reka!

If you want to implement a new rest endpoint you'd register a new rest action. In a plugin you'd extend `BaseRestHandler` and make an `onModule(RestModule)` method and on your plugin and call `addRestAction`. You can get the body of the post with `request.content()`. For now the usual way to parse it is with `XContentFactory.xContent(request.content()).createParser(request.content())`.
