=== HTTP/REST clients and security
|
|
|
|
The {es} {security-features} work with standard HTTP
|
|
https://en.wikipedia.org/wiki/Basic_access_authentication[basic authentication]
|
|
headers to authenticate users. Since Elasticsearch is stateless, this header must
|
|
be sent with every request:
|
|
|
|
[source,shell]
|
|
--------------------------------------------------
|
|
Authorization: Basic <TOKEN> <1>
|
|
--------------------------------------------------
|
|
<1> The `<TOKEN>` is computed as `base64(USERNAME:PASSWORD)`
|
|
|
|

==== Client examples
|
|
|
|
This example uses `curl` without basic auth to create an index:
|
|
|
|
[source,shell]
|
|
-------------------------------------------------------------------------------
|
|
curl -XPUT 'localhost:9200/idx'
|
|
-------------------------------------------------------------------------------
|
|
|
|
[source,js]
|
|
-------------------------------------------------------------------------------
|
|
{
|
|
"error": "AuthenticationException[Missing authentication token]",
|
|
"status": 401
|
|
}
|
|
-------------------------------------------------------------------------------
|
|
|
|
Since no user is associated with the request above, an authentication error is
|
|
returned. Now we'll use `curl` with basic auth to create an index as the
|
|
`rdeniro` user:
|
|
|
|
[source,shell]
|
|
---------------------------------------------------------
|
|
curl --user rdeniro:taxidriver -XPUT 'localhost:9200/idx'
|
|
---------------------------------------------------------
|
|
|
|
[source,js]
|
|
---------------------------------------------------------
|
|
{
|
|
"acknowledged": true
|
|
}
|
|
---------------------------------------------------------
