Question

我正在使用低级别的rest API访问AWS中的Elastic Search（AWS服务）。 AWS提供HTTPS网址。以下代码位于名为com.example.configurations.EsConfig的SpringBoot配置类中。

@Bean
public RestClient restClient() throws Exception {
    RestClient restClient = RestClient.builder(new HttpHost(esHost, esPort))
            .setHttpClientConfigCallback(new RestClientBuilder.HttpClientConfigCallback() {
                @Override
                public HttpAsyncClientBuilder customizeHttpClient(HttpAsyncClientBuilder httpClientBuilder) {
                    HttpAsyncClientBuilder httpAsyncClientBuilder = null;
                    try {
                        httpAsyncClientBuilder = httpClientBuilder.setSSLContext(SSLContext.getDefault());
                    } catch (NoSuchAlgorithmException e) {
                        e.printStackTrace();
                    }
                    return httpAsyncClientBuilder;
                }
            })
            .setRequestConfigCallback(requestConfigBuilder -> requestConfigBuilder.setConnectTimeout(5000)
                    .setSocketTimeout(60000))
            .setMaxRetryTimeoutMillis(60000)
            .build();
    return restClient;
}

对于esHost，我只提供AWS Elasticsearch端点URL，例如localhost。

对于esPort，如果是HTTPS，则为443。

以下是错误消息：

我无法通过SSL连接获取RestClient。请告诉我通过SSL连接获取RestClient所需的内容。感谢

我解决了传递＆＃34; https＆＃34;同时创建HttpPost对象作为第三个参数。

RestClient restClient = RestClient.builder(new HttpHost(esHost, esPort, "https"))
            .setHttpClientConfigCallback(httpClientBuilder -> {
                HttpAsyncClientBuilder httpAsyncClientBuilder = httpClientBuilder.setSSLContext(sslcontext);
                return httpAsyncClientBuilder;
            })
            .build();

现在工作正常。

使用低级别Rest API进行SSL / HTTPS连接？
