WARNING: Deprecated in 7.15.0.
The Java REST Client is deprecated in favor of the Java API Client.
Grant API key API
editGrant API key API
editCreates an API key on behalf of another user.
Grant API key request
editThis API is similar to Create API Key API, however it creates the API key for a user that is different than the user that runs the API.
A GrantApiKeyRequest
contains authentication credentials for the user on whose behalf
the API key will be created, a grant type (which indicates whether the
credentials are an access token or a user ID and password), and API key details.
The API key details include a name for the API key, an optional list of role
descriptors to define permissions, and an optional expiration for the
generated API key. If expiration is not provided, by default the API keys do not
expire.
CreateApiKeyRequest createApiKeyRequest = new CreateApiKeyRequest(name, roles, expiration, refreshPolicy, metadata); GrantApiKeyRequest.Grant grant = GrantApiKeyRequest.Grant.passwordGrant(username, password); GrantApiKeyRequest grantApiKeyRequest = new GrantApiKeyRequest(grant, createApiKeyRequest);
Synchronous execution
editWhen executing a GrantApiKeyRequest
in the following manner, the client waits
for the CreateApiKeyResponse
to be returned before continuing with code execution:
CreateApiKeyResponse apiKeyResponse = client.security().grantApiKey(grantApiKeyRequest, RequestOptions.DEFAULT);
Synchronous calls may throw an IOException
in case of either failing to
parse the REST response in the high-level REST client, the request times out
or similar cases where there is no response coming back from the server.
In cases where the server returns a 4xx
or 5xx
error code, the high-level
client tries to parse the response body error details instead and then throws
a generic ElasticsearchException
and adds the original ResponseException
as a
suppressed exception to it.
Asynchronous execution
editExecuting a GrantApiKeyRequest
can also be done in an asynchronous fashion so that
the client can return directly. Users need to specify how the response or
potential failures will be handled by passing the request and a listener to the
asynchronous grant-api-key method:
The asynchronous method does not block and returns immediately. Once it is
completed the ActionListener
is called back using the onResponse
method
if the execution successfully completed or using the onFailure
method if
it failed. Failure scenarios and expected exceptions are the same as in the
synchronous execution case.
A typical listener for grant-api-key
looks like:
Grant API key response
editThe returned CreateApiKeyResponse
contains an ID, API key, name for the API key, and
optional expiration.
