无法使用指定的节点进行身份验证 - ElasticSearch

Question

在azure中使用nest client 7.2.1连接elastic db内部负载均衡器。

 const string Url = "http://192.168.0.4:9200"; 
            var settings = new ConnectionSettings(new Uri(Url));
            ElasticSearchClient = new ElasticClient(settings);

            var indexes = GetAsxIndexes();

            var response = ElasticSearchClient.Ping().DebugInformation;

Answer 1

以下代码解决了我的问题

//Reading the configuration from appsettings.json
var elasticConfig = hostContext.Configuration.GetSection("ElasticSearch");

// 1. Register NEST ElasticClient
var settings = new ConnectionSettings(new Uri(elasticConfig["Uri"]))
                    .BasicAuthentication(elasticConfig["UserName"], elasticConfig["Password"])
                    .DefaultIndex(elasticConfig["DefaultIndex"]);

settings.PrettyJson();

var client = new ElasticClient(settings);

Answer 2

您正在尝试根据错误消息向已启用安全性的 Elasticsearch 集群发出请求

无法通过指定节点进行身份验证。尝试验证您的凭据或检查您的 Shield 配置。调用：状态码 401 来自：HEAD /

您需要在ConnectionSettings 中提供身份验证凭据以供客户端使用

var pool = new SingleNodeConnectionPool(new Uri("http://192.168.0.4:9200"));

var settings = new ConnectionSettings(pool)
    // configure the client with authentication credentials
    .BasicAuthentication("user", "password");


var client = new ElasticClient(settings);
