在JEST弹性搜索其余Java API中使用SSL证书合并的问题

Question

我在使用Jest API连接到elasticsearch（ELK）时遇到问题。我正在为ELK寻找基于休息的java API，它支持SCROLL＆amp; SCAN并且还支持基于证书的身份验证。

我发现Jest和Flummi是可用的。

由于Jest很受欢迎且有更多支持，我正试图使用​​它。

我的ELK数据库需要一个身份验证证书，我已在个人证书中安装。

我的问题是如何使用Jest Client对证书进行Http请求？我找到了一些代码，但它可以帮助我。我的代码如下。

            // clear a single scroll id
            ClearScroll clearScroll = new ClearScroll.Builder().addScrollId(scrollId).build();
            result = client.execute(clearScroll);          
        }  
}

请问这个问题。

private SSLContext createSSLContext() {
        try {
            SSLContextBuilder sslBuilder = SSLContexts.custom().loadTrustMaterial(null, (x509Certificates, s) -> true);
            final SSLContext sslContext = sslBuilder.build();
            return sslContext;
        } catch (Exception e) {
            LOGGER.error("cannot create SSLContext", e);
        }
        return null;
}
