Elasticsearch RestHighLevelClient通过代理在公司防火墙后

Question

我正在尝试从我们的网络访问cloud Elasticsearch安装，这需要使用外部请求的代理。这是我用来传递Elasticsearch凭据和代理设置的代码片段：

CredentialsProvider CredentialsProvider=new BasicCredentialsProvider（）；CredentialsProvider.SetCredentials（AuthScope.Any,new UsernamePasswordCredentials（elasticUser,elasticPassword））；

线程“Main”ElasticSearchStatusException中出现异常[Elasticsearch异常[Type=Security_Exception,Reason=Action[Indexs:Data/Read/Search]需要身份验证]]

似乎由于某种原因没有通过Elasticsearch凭据。

Answer 1

应该是这样做的：

RestClientBuilder restClientBuilder = RestClient.builder(new HttpHost(hostName, port, "https"))
    .setHttpClientConfigCallback(clientBuilder -> {
      clientBuilder.setDefaultCredentialsProvider(credentialsProvider);
      clientBuilder.setProxy(new HttpHost(proxyURL, proxyPort, "http"));
      return clientBuilder;
     });
