索引时出现 Bad Request 错误

Question

我已经下载并配置了 ElasticSearch。当我尝试使用 elasticsearch 客户端（即 Nest）为实例编制索引时，我得到 "The remote server returned an error: (400) Bad Request" error.What 问题可能是什么？

static void Main(string[] args)
        {
                const string folderLocation = @"\c:\elmah-exceptions\";
                var ElasticSearchServerURI = "http://localhost:9200";
                var defaultIndex = "Prod";
                var uri = new Uri(ElasticSearchServerURI);
                var connectionSettings = new ConnectionSettings(uri, defaultIndex).EnableTrace(true).ExposeRawResponse(true);
                var elasticClient = new ElasticClient(connectionSettings);

                var files = GetFiles(folderLocation);
                foreach (var file in files)
                {
                    var error = ParseFile(file);
                    if (error != null)
                    {
                        elasticClient.Index(error);//I get an error on this line
                    }
                }         
        }

public class Error
    {
        public string errorType { get; set; }
        public string message { get; set; }
        public string source { get; set; }
        public string errorArea { get; set; }

        public string queryString { get; set; }
        public string siteId { get; set; }
        public string model { get; set; }
        public string eolUserName { get; set; }
        public string name { get; set; }

        public string httpClientSrcIP { get; set; }
        public string errorTime { get; set; }
        public string sessionId { get; set; }
        public string httpSoapAction { get; set; }
        public string pathTranslated { get; set; }
        public string httpReferer { get; set; }

        public string sessionStartQueryString { get; set; }

        public string file { get; set; }
        public string host { get; set; }
    }

解决方法是默认索引应为小写。

static void Main(string[] args)
        {
                const string folderLocation = @"\c:\elmah-exceptions\";
                var ElasticSearchServerURI = "http://localhost:9200";
                var defaultIndex = "prod";
                var uri = new Uri(ElasticSearchServerURI);
                var connectionSettings = new ConnectionSettings(uri, defaultIndex).EnableTrace(true).ExposeRawResponse(true);
                var elasticClient = new ElasticClient(connectionSettings);

                var files = GetFiles(folderLocation);
                foreach (var file in files)
                {
                    var error = ParseFile(file);
                    if (error != null)
                    {
                        elasticClient.Index(error);//I get an error on this line
                    }
                }         
        }

public class Error
    {
        public string errorType { get; set; }
        public string message { get; set; }
        public string source { get; set; }
        public string errorArea { get; set; }

        public string queryString { get; set; }
        public string siteId { get; set; }
        public string model { get; set; }
        public string eolUserName { get; set; }
        public string name { get; set; }

        public string httpClientSrcIP { get; set; }
        public string errorTime { get; set; }
        public string sessionId { get; set; }
        public string httpSoapAction { get; set; }
        public string pathTranslated { get; set; }
        public string httpReferer { get; set; }

        public string sessionStartQueryString { get; set; }

        public string file { get; set; }
        public string host { get; set; }
    }
