editElasticsearch Token Service tokens
editIf you want the client to authenticate with an Elasticsearch access token, set the relevant HTTP request header.
If the client makes requests on behalf of a single user only, you can set the necessary Authorization header as a default header as shown
in the following example:
RestClientBuilder builder = RestClient.builder(
new HttpHost("localhost", 9200, "http"));
Header[] defaultHeaders =
new Header[]{new BasicHeader("Authorization",
"Bearer u6iuAxZ0RG1Kcm5jVFI4eU4tZU9aVFEwT2F3")};
builder.setDefaultHeaders(defaultHeaders);
Elasticsearch API keys
editIf you want the client to authenticate with an Elasticsearch API key, set the relevant HTTP request header.
If the client makes requests on behalf of a single user only, you can set the necessary Authorization header as a default header as shown
in the following example:
String apiKeyId = "uqlEyn8B_gQ_jlvwDIvM";
String apiKeySecret = "HxHWk2m4RN-V_qg9cDpuX";
String apiKeyAuth =
Base64.getEncoder().encodeToString(
(apiKeyId + ":" + apiKeySecret)
.getBytes(StandardCharsets.UTF_8));
RestClientBuilder builder = RestClient.builder(
new HttpHost("localhost", 9200, "http"));
Header[] defaultHeaders =
new Header[]{new BasicHeader("Authorization",
"ApiKey " + apiKeyAuth)};
builder.setDefaultHeaders(defaultHeaders);
