Basic authenticationedit
Configuring basic authentication can be done by providing an
HttpClientConfigCallback while building the RestClient through its builder.
The interface has one method that receives an instance of
org.apache.http.impl.nio.client.HttpAsyncClientBuilder
as an argument and has the same return type. The http client builder can be
modified and then returned. In the following example we set a default
credentials provider that requires basic authentication.
final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
credentialsProvider.setCredentials(AuthScope.ANY,
new UsernamePasswordCredentials("user", "password"));
RestClient restClient = RestClient.builder(new HttpHost("localhost", 9200))
.setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
@Override
public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
}
})
.build();
