Elasticsearch rest客户端http over https问题

rest ssl https

Elasticsearch rest客户端http over https问题,rest,elasticsearch,ssl,https,resthighlevelclient,Rest,elasticsearch,Ssl,Https,Resthighlevelclient,我正在尝试以下API @Autowire private final RestHighLevelClient restHighLevelClient; var restClient = restHighLevelClient.getLowLevelClient(); Response response = null; try { var request = new Request("GET", "/_cat/indices?v&f

我正在尝试以下API

@Autowire private final RestHighLevelClient restHighLevelClient;
var restClient = restHighLevelClient.getLowLevelClient();
    Response response = null;
    try {
      var request = new Request("GET", "/_cat/indices?v&format=json");
      response = restClient.performRequest(request);
    } catch (IOException e) {
      log.warn(e.toString(), e);
    }

    var entity = response.getEntity();
    if (entity != null) {
      log.info("content:" + IOUtils.toString(entity.getContent(), StandardCharsets.UTF_8));
    }

elasticsearch服务器在https上运行，这是创建客户端的bean

@Bean(destroyMethod = "close")
  public RestHighLevelClient client() {
    var connUri = URI.create(esClusterUrl);
    String[] auth = connUri.getUserInfo().split(":");

    var credentialsProvider = new BasicCredentialsProvider();
    credentialsProvider.setCredentials(
        AuthScope.ANY, new UsernamePasswordCredentials(auth[0], auth[1]));

    var builder =
        RestClient.builder(new HttpHost(connUri.getHost(), connUri.getPort()))
            .setHttpClientConfigCallback(
                httpClientBuilder ->
                    httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));
    return new RestHighLevelClient(builder);

我得到的错误响应是

2021-04-11 21:13:07.822  WARN 40680 --- [           main] com.document.feed.util.ESMaintenance     : org.elasticsearch.client.ResponseException: method [GET], host [http://yew-739425389.eu-west-1.bonsaisearch.net:443], URI [/_cat/indices?v&format=json], status line [HTTP/1.1 400 Bad Request]

普通HTTP请求已发送到HTTPS端口

这是非常自我解释的，这意味着我应该在进行http rest调用时对服务器进行https调用。解决方案是什么？

通过在构建客户端时切换到https方案来解决

var builder =
        RestClient.builder(new HttpHost(connUri.getHost(), connUri.getPort(), "https"))
            .setHttpClientConfigCallback(
                httpClientBuilder ->
                    httpClientBuilder.setDefaultCredentialsProvider(credentialsProvider));
    return new RestHighLevelClient(builder);
