使用带有 RestHighLevelClient 的 Basic-Auth-Proxy 后面的 ElasticSearch 端点

Question

我有一个 ElasticSearch 集群，它位于配置了基本身份验证的代理后面。如何使用凭据从 RestHighLevelClient 拨打电话？在 SpringBoot 中，您通常必须像这样配置 HttpClientContext：

@Bean
public HttpClientContext configuredContext() {
    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(DEFAULT_USER, DEFAULT_PASS));

    AuthCache authCache = new BasicAuthCache();
    authCache.put(httpHost, new BasicScheme());

    final HttpClientContext context = HttpClientContext.create();
    context.setCredentialsProvider(credsProvider);
    context.setAuthCache(authCache);
    return context;
}

但我在 ClientBuilder 或上下文中找不到任何合适的参数。有什么方法可以使这个设置起作用吗？

您可以创建 RestHighLevelClient 实例为

final CredentialsProvider credentialsProvider = new BasicCredentialsProvider();
    credentialsProvider.setCredentials(AuthScope.ANY,
            new UsernamePasswordCredentials("user", "password"));

    RestClientBuilder builder = RestClient.builder(new HttpHost("server", port))
            .setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                @Override
                public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                    return httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider);
                }
            });

    RestHighLevelClient client = new RestHighLevelClient(builder);
