使用RestHighLevelClient在基本身份验证代理后面使用ElasticSearch端点

elasticsearch spring-boot spring java

Phil · 技术社区 · 7 年前

我有一个ElasticSearch集群,它位于配置了基本身份验证的代理之后。如何使用凭据从RestHighLevelClient拨打电话?在SpringBoot中,您通常必须如下配置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或上下文请求中找不到任何拟合参数。有什么方法可以让这个设置工作吗?

您可以创建 RestHighLevelClient

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);
