Question

我使用elasticsearch 7和nest 6.7。

我有任何类型的索引，例如坐标。

以任何方式在映射geo_type时我都有问题。

 client.CreateIndex("staging2", c => c.Mappings(m => m.Map<VenueIndex>(mm => mm.AutoMap())));

这是我的嵌套代码，这是poko类的som部分：

     public object Promotion { get; set; }
    public object Checkin { get; set; }
    public Featured Featured { get; set; }
    public int BinaryType { get; set; }
    public List<WorkingHour> WorkingHours { get; set; }
    [GeoPoint(Name = "location", IgnoreMalformed = true)]
    public Geoloc _geoloc { get; set; }
    public string Neighbourhood { get; set; }
    public List<int> MealTimes { get; set; }
    public string objectID { get; set; }

    public class Geoloc
{

    [Number(NumberType.Double, Name = "lat")]
    public double lat { get; set; }
    [Number(NumberType.Double, Name = "lon")]
    public double lon { get; set; }
}

通过这种方式，GeoLoc类型为浮点型

当我发布帖子时，其他方式仍然存在此问题。

我的json对象是这样的：

{
  "isClubMember": false,
 "rating": 0.0,
 "binaryType": 2,
 "location": {
 "lat":"32.11",
 "lon":"-34.22"
 },
   "neighbourhood": "شهرک والفجر,امیر آباد",
   "mealTimes": [],
   "objectID": "188dc91e-8088-4099-9eb8-00aa73653192"}

我的错误在哪里？

使用NEST创建映射的代码

    public class TestClass
    {
        public object Promotion { get; set; }
        public object Checkin { get; set; }
        [GeoPoint(Name = "location", IgnoreMalformed = true)]
        public Geoloc _geoloc { get; set; }
        public string Neighbourhood { get; set; }
        public List<int> MealTimes { get; set; }
        public string objectID { get; set; }
    }
    public class Geoloc
    {
        [Number(NumberType.Double, Name = "lat")]
        public double lat { get; set; }
        [Number(NumberType.Double, Name = "lon")]
        public double lon { get; set; }
    }

输出映射：

var url = "http://localhost:9200";
            var settings = new ConnectionSettings(new Uri(url));
            EsClient = new ElasticClient(settings);

            if (!EsClient.IndexExists("gcheck").Exists)
            {
                var resp = EsClient.CreateIndex("gcheck", c => c
                 .Map<TestClass>(mp => mp
                 .Properties(
                     ps => ps
                 ).AutoMap()
                ));
            }

我如何将lat和lng映射到elasticsearch中的geo_point类型
