C# MongoDB GeoJsonPoint JSON 对象

Question

我遇到了如何使用 mongodb.driver

在我的 ASP.NET Core 3 应用程序中构造我的地理位置对象的问题

我的对象

public class Person
{
    [BsonId]
    public ObjectId Id { get; set; }

    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public string Address { get; set; }
    public string State { get; set; }
    public string ZipCode { get; set; }
    public string PhoneNumber { get; set; }
    public GeoJsonPoint<GeoJson2DGeographicCoordinates> Location { get; set; }
}

我只是在做一个直线插入并传递对象。如果我遗漏了它插入的位置。

这是我试图通过简单的 post.

传递给 api 的 JSON 对象

{
"firstName": "Paul",
"lastName": "Staley",
"email": "someemail@nowhere.com",
"address": "12345 E 1st Ave",
"state": "AA",
"zipCode": "11111",
"phoneNumber": "555-555-5555",
"location":  {

    "coordinates": [
        0.123321,
        0.3453455
    ]
}

}

我得到的错误。

System.NotSupportedException：不支持没有无参数构造函数的引用类型的反序列化。输入 'MongoDB.Driver.GeoJsonObjectModel.GeoJsonPoint`1[MongoDB.Driver.GeoJsonObjectModel.GeoJson2DGeographicCoordinates]'

人物对象

 public class Person
 {
    [BsonId]
    public ObjectId Id { get; set; }

    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public string Address { get; set; }
    public string State { get; set; }
    public string ZipCode { get; set; }
    public string PhoneNumber { get; set; }
    public double Latitude { get; set; }
    public double Longitude { get; set; }
    public GeoJsonPoint<GeoJson2DGeographicCoordinates> Location
    { get; private set; }
    public void SetLocation(double lon, double lat) => SetPosition(lon, lat);


    private void SetPosition(double lon, double lat)
    {
        Latitude = lat;
        Longitude = lon;
        Location = new GeoJsonPoint<GeoJson2DGeographicCoordinates>(
            new GeoJson2DGeographicCoordinates(lon, lat));
    }
}

控制器

 [HttpPost]
    public IActionResult CreatePerson(Person person)
    {
        person.SetLocation(person.Longitude, person.Latitude);
        _personRepository.CreatePerson(person);

        return Ok();
    }
